## Job Description

Ffern is a sustainable, mission-driven fragrance brand — and technology is at the heart of how we grow.

We're hiring a Senior Software Engineer to join one of our cross-functional product pods. You'll sit inside a small, focused team of engineer, designer, and growth lead, taking full ownership of revenue-driving customer journeys across acquisition, retention, and lifecycle. Expect fast, iterative work — A/B testing, continuous improvement, and staying close to what you ship.

We're a small, ambitious team building something genuinely different in the fragrance world. The work is high impact, the stack is modern, and there's real ownership on offer from day one.

The work....

- Take full ownership of at least one core customer journey — from architecture through to post-release monitoring.
- Work closely with design and growth to design and implement experiments across acquisition, retention, and lifecycle.
- Constantly improve your area of ownership, both technically and from a growth perspective.
- Support fellow engineers across pods.

Our stack....

We run a monorepo architecture managed by Turborepo. Our core technologies include Next.js, PostgreSQL (via Supabase), QStash, Redis, Sanity, Prisma, and Growthbook. We deploy daily and keep our CI/CD lean.

What we need....

- 4+ years as a full-stack engineer, ideally with D2C or e-commerce experience.

- You've shipped A/B tests to production.

- You're comfortable with uncertainty and you push hard to get things over the line.

Beyond the technical skills, senior engineers at Ffern are:

- Owners — they take a feature from brief to production without being chased.
- Rigorous testers — they QA their own work and their colleagues'.
- Observant — they add logging, monitor post-release, and use feature flags as standard.
- AI-curious — they actively use AI tools to work faster and smarter.
- Multipliers — they make the engineers around them better.

We're a small, ambitious team building something genuinely different in the fragrance world. The work is high impact, the stack is modern, and there's real ownership on offer from day one.
