Which team will you be joining?
The mer
chant experien
ce is only as good as the platform behind it.
In the A
ccount Experien
ce team we build and own the full platform that mer
chants use to intera
ct with Primer — from initial setup through to day-to-day operations, and in
creasingly through Primer AI
Companion as a first-
class interfa
ce.
This team
covers: Primer
Companion, Mer
chant A
ccount Setup, Monitors, Workflows, Auditing, and
cross-
cutting platform
con
cerns that keep the mer
chant experien
ce
cohesive and
consistent.
As a
class="bg-amber-100">Ba
ckend
Engineer L3 you will work within a small, high-
calibre team of
engineers who own their work end to end. You'll report into the
Engineering Manager for A
ccount Experien
ce and
contribute to systems that power the mer
chant platform at s
cale.
What will you be doing?
- Take full ownership of class="bg-amber-100">backend features from scoping through to production, keeping the team informed on progress, risks, and blockers without being chased.
- Design and deliver class="bg-amber-100">backend services that handle real payment volume, with a strong focus on reliability, performance, and correctness at scale.
- Contribute to architecture discussions, bring proposals to the engineering council, and advocate for clear service contracts and simple, maintainable system design.
- Monitor the production impact of your own work, identify issues early, and drive incidents to resolution when they arise.
- Write code that your peers consider high quality: production-ready, well-considered on error paths, and built with the next engineer in mind.
- Actively contribute to Primer's engineering standards, raise concerns when you see gaps, and help the team hold a consistent bar.
- Collaborate with engineers across the Account Experience team on scoping sessions, code reviews, and class="bg-amber-100">technical decisions that shape how the system evolves.
What We're Looking For
- Solid class="bg-amber-100">backend engineering experience, with the ability to take ambiguous requirements and deliver working, production-ready software with minimal direction.
- Strong grasp of distributed systems fundamentals: you understand why things fail in production and you build accordingly.
- Comfortable working with class="bg-amber-100">REST APIs and the patterns that make services reliable, observable, and easy to reason about.
- Experience owning work end to end — not just writing code but thinking about monitoring, rollout, and what happens after deployment.
- The confidence to contribute to architecture discussions, ask the right questions, and push back when a design decision doesn't make sense.
- Experience in a payments, fintech, or class="bg-amber-100">infrastructure context is a plus, though depth of engineering matters more than the specific industry.
You may not like it here
- Primer is remote-first. There is no office to fall back on when you want context, direction, or a sense of how things are going. You need to be good at operating without those signals.
- We do not over-engineer our processes. If something is unclear, you're expected to resolve that ambiguity yourself rather than wait for someone to remove it.
- The Orchestration codebase is not simple. You will inherit class="bg-amber-100">technical complexity and will be expected to deal with it thoughtfully, not just work around it.

What's the class="bg-amber-100">culture like at Primer?
We're building a
class="bg-amber-100">
culture where
class="bg-amber-100">people
can do their best work and be proud of the impa
ct they have. You'll be working with
class="bg-amber-100">people who are mission-driven, smart, and refle
ctive, and who are genuinely invested in building ex
ceptional produ
cts and delivering su
ccess for our mer
chants.
We work remotely, and have done sin
ce day one. We believe that building a su
ccessful, profitable
company goes beyond proximity. We invest in our relationships through great remote working pra
cti
ces and thoughtfully designed fa
ce-to-fa
ce time, in
cluding workations, our annual
company retreat, and a
ccess to
co-working spa
ces a
cross most major
cities.
The work is
challenging. S
caleups are a
challenge, and building
category-defining produ
cts is a
challenge. But there's a meaningful differen
ce between a
challenge and a struggle. At Primer, the right
challenge
comes with the right support: strong onboarding, a
collaborative environment, and a team that is genuinely invested in your su
ccess. It's never something you fa
ce alone.
