Frontend / UI Engineer
Owns the part the customer touches — and, at architect level, the structure that keeps a large interface maintainable.
Who to hire
The shape of person who does this job well — and whether you should be hiring it at all yet.
Pebl hires this specifically for invoicing and payments, and separately as a UI architect. Both are post-fit hires: the first says the money-handling screens are now critical, the second says the interface is big enough to need its own architecture. In a startup, a strong full-stack engineer covers this until the product's surface becomes the product.
Education
Rarely a degree question. Judge the work: an interface they built that is still in production and still being extended.
Experience
4+ years, 7+ for architecture. Specific evidence of accessibility, performance and state management — the three things that go wrong at scale and are nearly impossible to retrofit.
Vertical / domain experience
Matters in two cases: money on screen (invoicing, payments, trading), where correctness and auditability dominate, and heavily regulated accessibility requirements. Otherwise general frontend skill transfers well.
What it pays, roughly
$90,002 median, Canada — for Computer, software and Web designers and developers, the closest occupation Statistics Canada actually measures, measured from $69,992 to $117,499 over 276,895 people. That occupation is broader than this role, so read it as an anchor, not a salary band — and note that a startup usually pays below it in cash and above it in equity.
Credentials and certifications
What exists, who issues it, and whether it means anything for this seat. A credential is evidence of a floor, never of judgment — and in a few of these roles it is a legal requirement rather than a nice-to-have.
| Credential | Issued by | When it matters |
|---|---|---|
| WAS — Web Accessibility Specialist | International Association of Accessibility Professionals | The one credential in this area that means something concrete. |
What this role does at each stage
The same title means three different jobs depending on how much money is in the bank. Read the stage you are at, then read the next one — that is what you are hiring toward.
Nobody — the founder or the first engineer builds the interface with an off-the-shelf component library.
Covered by a full-stack engineer. A dedicated frontend hire this early is usually a sign the team is specialising too soon.
A real seat, and the point to settle the design-system question — one component library, owned, versioned and documented, rather than three.
Can one person hold this and something else?
The whole point of the many-hats problem: which of these jobs merge safely into one person, and which merges quietly cost you money or control.
Merges well with
- Design Systems Lead (Product & design)
- Software Engineer
Frontend engineer + designer is the single highest-leverage pairing in a small product team, and in one person it is a genuine superpower. Frontend + full-stack is the default at seed.
Keep separate from
A CTO who owns a delivery surface will be pulled into sprint work exactly when architectural decisions need making.
Reading a candidate
What good looks like in an hour, and what should stop the process.
Good signals
- Cares about the keyboard and the screen reader without being asked
- Has opinions about state management grounded in something that broke
- Can read a design and spot the case the designer missed
Red flags
- Framework loyalty over problem fit
- No testing of anything visual
- Treats accessibility as a later ticket
