About Helix

Company

Helix Software builds compliance tooling for fintech companies — the unglamorous but critically important layer that keeps financial products from running into regulatory walls. Our customers are compliance teams at neobanks, lending platforms, and payment companies who need to move fast without creating legal liability.

We raised our Series A 14 months ago, we're at $6M ARR and growing, and we're at the part of the journey where the early architectural decisions start to matter a lot. That's why this hire matters.

The Role

We're looking for a senior full-stack engineer who wants to own their domain end-to-end. You're not a ticket-doer — you're a builder. You'll work across the stack (Next.js frontend, Go services, Postgres), make architectural decisions, and ship product features that real compliance professionals use every day.

This is a remote-first role. We have a small office in SF that some people use sometimes, but the team runs async-first with intentional sync time (one weekly all-hands, one team video sync, on-call rotation 1 week per quarter).

Responsibilities

• Ship product features end-to-end — from product spec to deployed code in production
• Own architecture decisions for your domain; you're expected to push back on bad ideas (including ours)
• Review PRs for 1–2 other engineers; give real feedback, not rubber stamps
• Participate in on-call rotation (1 week per quarter) — we have good runbooks and it's genuinely quiet
• Mentor 1–2 junior engineers; not a management track, just technical guidance
• Collaborate with product and design to shape what gets built, not just how

Requirements

What We Need

Required

5+ years of professional software engineering experience with a strong production track record

Required

Strong TypeScript — you can write it cleanly, type it properly, and you have opinions about when generics are worth it

Required

At least 2 years of production Go, or an honest willingness to pick it up fast (we'll know in the technical screen)

Required

Experience with PostgreSQL at scale — schema design, query optimization, migrations without downtime

Required

You've shipped B2B products that real companies use and pay for — you know what "production quality" actually means

Required

Nice to Have

Fintech or compliance domain experience — you know what a KYC flow or AML report actually is

Bonus

Experience working in SOC 2 Type II environments — data handling requirements, audit logs, security controls

Bonus

Open source contributions — anything shipped that other people use

Bonus

Experience with Redis for caching, pub/sub, or rate limiting
