A 1-Year Cliff and a Bad Strike Price Cost One Singapore Startup Its Lead Engineer — the 7-Step ESOP Playbook I Now Run With Founders

The engineer had joined a Singapore fintech as employee number four, built most of the platform, and been promised one and a half percent. Eleven months in, a competing offer arrived and he asked the founders for his grant letter to compare the two. That was when everyone discovered that the board had approved his grant four months after he started, that the vesting commencement date had been set to the approval date, and that his one-year cliff was therefore fifteen months away. The strike price on the letter was the last preference share price, which nobody could explain. He took the other job three weeks later, and the founders lost the person who understood their codebase over two dates and a number. I have since run the same seven-step review with a number of Singapore founders, and I have not seen that particular failure again. Here it is.

Why ESOPs Fail Engineers in Singapore Specifically

Three local facts make Singapore ESOPs easier to get wrong than founders expect. First, a private company here is capped at fifty shareholders, so early-stage plans are almost always structured as options rather than shares, and options are governed by paperwork — grant dates, exercise prices, expiry windows — that engineers rarely see until it matters. Second, Singapore taxes option gains as employment income at the point of exercise, not at sale, so the design of the strike price has direct cash consequences for the engineer. Third, a large share of Singapore’s senior engineers are on Employment Passes, and a specific IRAS rule applies to them when they leave Singapore employment that most founders have never heard of.

The authoritative reference on the tax side is IRAS’s e-Tax Guide, Tax Treatment of ESOP and Other Forms of ESOW Plans. It is not light reading, and nothing here replaces advice from your tax adviser and corporate secretary, but every founder issuing options should have read at least the sections on the timing of taxation and the deemed exercise rule before signing a grant letter.

Step 1: Size the Option Pool Before the First Engineering Offer

Decide the pool as a percentage of fully diluted shares — every issued share, every option granted or reserved, every convertible as if converted. Seed-stage Singapore companies commonly reserve somewhere around ten to fifteen percent, and investors will usually ask for the pool to be created or topped up before their money comes in, so that the dilution from the pool falls on the founders rather than on them. Know that going in.

Then model the dilution forward. A one percent grant today is not one percent at exit; it is one percent divided by whatever the next two rounds do to the share count. Build a simple spreadsheet with the current cap table, the pool, and two hypothetical rounds, and keep it current. The engineer you are about to hire will ask what their percentage becomes after the Series A, and “we haven’t modelled that” is an answer that tells them how seriously you take the grant.

Finally, reserve grants for the hires you are making now. The commonest sizing mistake is holding the pool back for a hypothetical VP of Engineering two years out while offering the people building the product today a fraction of a percent. If the product is being built now, the equity should be going to the people building it now.

Step 2: Choose the Instrument: Options, RSUs or Phantom Equity

For most Singapore startups hiring their first ten engineers the answer is options, and the reason is the shareholder cap: an option holder is not a shareholder until they exercise, which keeps the company private and the cap table clean through the years when it matters most. For remote engineers you employ through an EOR in another country, phantom equity is often the honest choice — see our note on Employment Pass, CPF and EOR routes for hiring developers in Singapore for how the employment structure interacts with what you can grant.

Step 3: Set Vesting That Starts on the Engineer’s First Day

The standard schedule is four years, a one-year cliff, then monthly: nothing vests in the first twelve months, a quarter vests at the twelve-month mark, and one forty-eighth vests each month after that. It is standard because it works — it protects the company from a hire that does not work out, and it gives the engineer a steadily increasing reason to stay.

The failure in the story above was not the schedule. It was the vesting commencement date. Grants have to be approved by the board and, depending on your constitution, sometimes by shareholders, and that approval can lag the start date by months while everyone is busy. If the commencement date is set to the approval date, every month of delay silently extends the cliff. The fix is one line in the plan rules and the grant letter: vesting commences on the employee’s start date regardless of the date of grant. Then hold the board to approving grants within thirty days of each start date, and put that on the agenda of every board meeting.

Step 4: Price the Strike So Exercising Is Rational

In Singapore, the gain on an ESOP is taxed as employment income when the option is exercised, on the difference between the open market value of the shares at that point and the exercise price. That single fact drives strike price design. A strike set too high — at the last preference share price, say, which carries liquidation preferences and other rights ordinary shares do not — leaves the engineer with options that may be worth little even at a good exit. A strike set to a nominal value with no justification leaves the engineer with a large taxable gain at exercise and the company with a governance question from its next investor.

The defensible middle is a fair market value of the ordinary shares, documented. Singapore does not impose a formal valuation regime for private-company option pricing the way some jurisdictions do, but investors, auditors and the engineer’s own adviser will ask how the number was reached. A short memo explaining the method — typically a discount to the last round’s preference price reflecting the rights ordinary shares lack, or a simple valuation from your corporate secretary or accountant — is enough. Attach it to the board resolution. Rerun it after each round.

Then do the arithmetic the engineer will do. If the strike is S$0.50 and the shares are worth S$5.00 when they leave or the company exits, exercising 100,000 options costs S$50,000 in cash and creates a S$450,000 gain taxed as income. Can they fund that? If not, the plan needs either a cashless exercise mechanism, a longer exercise window (Step 6), or the QEEBR deferral in Step 5. A grant the holder cannot afford to exercise is a grant that does not retain them.

Step 5: Handle the Deemed Exercise Rule for Foreign Engineers Up Front

This is the step founders most often do not know exists. Under the deemed exercise rule described in the IRAS e-Tax Guide, when an employee who is not a Singapore citizen or permanent resident ceases employment in Singapore with unexercised options, the gains on those options are treated as income derived one month before the date of cessation (or the date of grant, if later), computed on the open market value of the shares at that point. In plain terms: an Employment Pass engineer who leaves your company and Singapore can be taxed on options they have not exercised and may never exercise.

There are two mitigations, and both are the employer’s to arrange. The tracking option lets an approved employer track the foreign employee after they leave and report the gain to IRAS when the options are actually exercised or the shares actually vest, instead of on departure. The QEEBR scheme allows eligible employees to defer the tax on qualifying gains for up to five years, with an interest charge, which addresses the liquidity problem of paying tax on shares that cannot yet be sold. Both have conditions; read the guide and talk to your adviser.

What you must do regardless is tell the engineer in the offer letter. A senior engineer on an Employment Pass who learns about the deemed exercise rule from a tax clearance form in their last month will, rightly, feel misled. One paragraph in the offer — the rule exists, here is what it means, here is what the company will do about it — is the difference between a grant that feels like a benefit and one that feels like a trap. It also belongs in your developer compensation package template.

Step 6: Write Leaver Terms and an Exercise Window a Good Engineer Would Accept

Three clauses decide whether vested options are ever worth anything to an engineer who leaves.

• Good leaver / bad leaver. Define bad leaver narrowly — gross misconduct, breach of restrictive covenants, that kind of thing — and make everyone else a good leaver who keeps their vested options. Plans that make resignation a bad-leaver event are read by engineers as “you only keep this if we decide you can,” and priced accordingly.
• Post-termination exercise window. Ninety days is the historical default and the reason most vested options are forfeited: it demands cash for the strike and the tax exactly when the engineer is between jobs. A window of one to several years for good leavers is now common among founder-friendly Singapore plans and costs the company almost nothing, because the options are already vested and already in the fully diluted count.
• Acceleration on change of control. Use double-trigger: unvested options accelerate only if the company is acquired and the engineer is terminated without cause within a set period after. Single-trigger acceleration is what acquirers negotiate away, and engineers who have been through one exit know it.

These clauses cost founders nothing at grant and everything at the moment they are tested. Get them into the plan rules before the first grant, because retrofitting friendlier leaver terms later requires amending every existing grant and explaining why the old ones were worse. Our guide to handling counter-offers when hiring developers in Singapore covers the moment when these terms get compared side by side against a competitor’s.

Step 7: Issue a Grant Letter the Engineer Can Check

A grant letter is a retention document only if the engineer can verify it. Ours contains, on one page: the number of options; what that is as a percentage of fully diluted shares today; the strike price and the fair market value it was derived from; the vesting schedule with actual dates, including the cliff date; the post-termination exercise window; and three scenarios showing what the grant is worth net of strike at three exit valuations. Then an annual statement, every year, updated for dilution.

The three-scenario table is the part that founders resist and engineers value most. It forces the conversation about dilution and strike into the open at grant, where it is a design discussion, instead of at resignation, where it is an accusation. It also makes the grant comparable: a candidate weighing your offer against another startup’s can put the two tables side by side, and if yours is the only one that exists, you have already won part of the argument. That comparison is, in the end, what an ESOP is for — see our broader notes on retaining senior developers in Singapore for the rest of the retention picture.

If You Also Hire in Dubai

The instruments are similar but the tax picture is different — the UAE has no personal income tax on employment income, which changes the exercise arithmetic entirely, while the golden visa has become a retention lever in its own right. Our Dubai colleagues cover that in their guide to retaining AI engineers in Dubai with equity and the golden visa; the wider employer library is on the HireDeveloper.ae resources page. If your engineering team spans both hubs, the grant letters should differ in Steps 4 and 5 and be identical everywhere else.

Within Singapore, the practical next move is to pull the grant letters of your current engineers and check three things: the vesting commencement date against the start date, whether the strike price has a memo behind it, and whether any Employment Pass holder has been told about the deemed exercise rule. Fix whatever you find before you make the next offer. Our TypeScript and React benches are where most Singapore startups make that next offer, and we will tell you in advance which candidates will read the letter closely.
