The Job

Curie builds products at the intersection of elite engineering and user-centric design. They need someone who can own features end-to-end, from pixel-perfect frontend to working backend.

What you'll actually do:

• Ship frontend-heavy features in SvelteKit/Tailwind with obsessive attention to UI/UX quality

• Build backend features independently (NodeJS, Postgres, Fastify, queues) — you won't need someone to hold your hand

• Work in a high-autonomy environment: no code reviews unless you ask, no micromanagement, no gates

• Collaborate with senior team members in constant, direct communication

• Ship. Fast. With leverage.

The Stack

• FE: SvelteKit, Tailwind, DaisyUI, Playwright. Architecture patterns: DDD & CQRS

• BE: NodeJS, Postgres, Fastify, queues

• ML components: Python

• The tools aren't sacred. What matters is delivery, not the framework you used.

What You Need (Non-Negotiables)

• 5+ years fullstack experience shipping products that real users touch

• Expert-level TypeScript

• You've shipped 0→1 products at high-growth or early-stage startups

• End-to-end feature ownership (frontend + backend) is your default mode

• Deep resilience under pressure — bugs, crises, tight deadlines. You don't crack

• Elite communication: set expectations, deliver, no surprises

• Thrive in ambiguity. Self-manage. No manager needed

• No ego. Results > process

Nice to have: Ex-founder, Tailwind/DaisyUI/Playwright experience, CQRS/queues familiarity, Python for ML/AI, AI-first product development exposure

What You Don't Need

• Corporate hierarchy experience

• Large enterprise background

• Someone telling you what to do

• Structure, predictability, or work-life balance policies

Compensation

• Competitive base salary

• Equity as part of compensation

• Profit share for core team members

• Unlimited PTO — use your judgement, don't track days

The Process

1. Recruiter screening — fit and motivation check

2. 1-on-1 with Simon (senior team member) — culture and team alignment

3. Technical challenge (~4 hours, open book) — use AI, Google, whatever. We care about the result, not how you got there

4. Contract offer — one-month trial period, then extend to full-time

Apply If

• You thrive on ownership, not approval

• You're hungry to build, not manage

• You want real impact at a well-funded startup scaling fast

• You live in or can get to Warsaw

Don't apply if: You need managers, structure, predictability, or a traditional corporate environment. Those people won't last here.
