Job description

Senior Backend Engineer (Product Engineering)

Remote

• Eastern Hemisphere (timezone overlap required) #APJ #EMEA

FINN is a fintech company building simple and transparent products that improve financial well-being for underbanked employees. Our core offering gives people access to wages they have already earned, alongside tools to help them manage money better, build savings, access insurance, earn additional income, and use fairer financial services.

Founded in 2022, FINN is the largest player in the early wage access space in Southeast Asia and is expanding rapidly into new markets globally. We are looking for ambitious builders who take ownership, move fast, and want to shape products that create meaningful impact in people’s lives.

What you'll do

• Build and ship backend services that power our financial products — APIs, automation pipelines, and cloud infrastructure.
• Own features end-to-end: dig into the problem, design the approach, ship fast, and iterate based on real usage.
• Contribute to technical direction — advocate for better patterns, tooling, and developer experience.
• Partner with product and engineering to define solutions, not just execute specs.
• Write clean, reliable code at a high pace — quality and speed, not one or the other.
• Raise the bar for the team through code reviews, technical input, and leading by example.

How we work

We're a small team that values clear thinking over heavy process. Engineers get real context on the “why” and autonomy on the “how.” We ship frequently, learn from production, and make pragmatic tradeoffs. We plan enough to move confidently — but never so much that we slow down.

AI in our workflow

AI is becoming core to how we build. We use LLMs daily for coding, debugging, automated code reviews, design doc reviews, and we're building internal tooling to push this further in and out of the Engineering team. We expect engineers to use AI as a force multiplier in their daily work — and to contribute ideas on how we can do it better.

What we're looking for

• 5+ years shipping backend systems in production — APIs, services, cloud infrastructure.
• Strong fundamentals in at least one of our core languages (TypeScript, Python, PHP).
• Experience with cloud platforms (AWS and/or GCP), containerization, and CI/CD.
• Ability to operate independently: you take ownership of a problem and drive it forward.
• Pragmatic judgment on architecture vs. shipping and learning.
• Clear communicator who can articulate tradeoffs and advocate for their approach.

Our stack is TypeScript, Python, and PHP across AWS and GCP (Lambda, Cloud Functions, Firebase, Firestore). Strong engineers from other languages or cloud providers ramp quickly — we care more about fundamentals than specific stack experience.

This role probably isn't for you if

• You aren't comfortable with some level of ambiguity.
• You default to large rewrites when the problem needs solving in days.
• You optimize for architectural purity over learning from real users.
• You need a lot of structure or guidance to do your best work.

Why join

• Your work directly shapes the product experience for hundreds of thousands of users.
• Small, high-caliber team — minimal bureaucracy, fast feedback loops, clear business impact.
• High autonomy and real ownership from day one.
• A seat at the table in defining how backend engineering evolves here.
