You'll move fast, make real decisions, and have direct impact on a product used by people who care deeply about learning and research. We don't have managers. We have engineers who own their work. TECH STACK The stack is heavily TypeScript. On the frontend: SvelteKit, Tailwind, DaisyUI, and Playwright, with DDD and CQRS patterns. On the backend: Node.js, Fastify, PostgreSQL, and queues. ML components are in Python. The stack is pragmatic, not dogmatic — tools may shift as the product evolves. WHAT WE LOOK FOR Elite communication You set accurate expectations and live up to them.

You own the call. High-bandwidth collaboration Constant communication means everyone has context without formal gates or status meetings. Direct feedback Code reviews are blunt, concise, and respectful. We say what we mean. Ruthless efficiency We aggressively adopt any tool — AI included — that increases speed and leverage. Limited frontend test coverage Supplemented by strong architecture and top talent, not bureaucratic QA processes. RECRUITMENT PROCESS Recruiter screening — a short intro call to align on basics. 1-on-1 with the engineering lead — a conversation about how you think and work. Technical challenge (~4 hours) — use AI, Google, or any resource you need. We care about the result, not the method. One-month paid contract — with the possibility to extend indefinitely. Honest, frequent feedback throughout so you always know where you stand. COMPENSATION & BENEFITS Salary $100,000 – $150,000 depending on experience. Equity and profit share Core team members receive both equity and profit share as part of the compensation package. Unlimited PTO Use your own judgement — we won't count days. Steep learning curve You'll grow faster here than almost anywhere else — by design, not accident. Real ownership No managers capping your authority. You own your work end-to-end, with the full trust of the team behind you.

🏢 Summary: Senior Software Engineer role focused on building high-quality UI/UX-driven products with a predominantly TypeScript stack, while also handling backend features when needed. The position offers high autonomy, ownership, and direct impact in a startup environment with modern frontend, backend, and ML technologies. Candidates receive equity, profit sharing, and the opportunity for rapid financial and professional growth. 🗂️ Requirements: Expert-level software engineering experience, Strong UI/UX implementation skills, Ability to build frontend applications with TypeScript and SvelteKit, Ability to implement backend CRUD features independently, Experience with NodeJS and relational databases, Understanding of DDD and CQRS principles, Experience working with PostgreSQL, Proficiency in building and consuming APIs, Ability to work autonomously and take ownership of technical decisions, Strong communication skills in collaborative engineering environments 📃 Skills: TypeScript, SvelteKit, Tailwind, DaisyUI, Playwright, NodeJS, Postgres, Fastify, Python, DDD, CQRS, SQL 🏢 Description: Pre-requisites You are familiar with About Curie About you Now that you know a bit about us, let’s talk about you. You’re an expert software engineer with outstanding attention to UI/UX. When you need to ship backend features, you don’t need someone else to step in. We don’t expect a backend ninja, but simple CRUD shouldn’t intimidate you. The definition of "expert" varies, so let’s narrow ours down: Elite communication: You set expectations accurately and you live up to them. No surprises. Deep resilience: Bugs, crises, or tough discussions - you have a massive buffer before stress impacts your output. You don't crack under pressure. No ego: We are here to win, not to manage insecurities. Product mastery: You understand the engineering principles behind the greatest software products ever made. If you’re an ex-founder, that’s a bonus. If not, we’ll make you one. Tech stack Heavily dominated with Typescript FE: SvelteKit, Tailwind, DaisyUI, a bit of Playwright; DDD & CQRS BE: NodeJS, Postgres, Fastify, and queues ML parts are mostly in Python The technologies we use aren’t set in stone. We may shift tools occasionally; we care far more about value than the technology behind it. Engineering culture Optional code reviews: We trust you. Merge when you're ready. If you want a second pair of eyes, just ask. Radical autonomy: We don’t second-guess your decisions. You own the call. High-bandwidth collaboration: We talk constantly, so everyone has context without needing formal gates to catch up. Direct feedback: When we do review code, comments are blunt, concise, and respectful. Ruthless efficiency: We aggressively adopt any tool (AI included) that increases leverage and speed. Limited test coverage on FE : We supplement that with good architecture and top talent. Recruitment process Complete our quick form Short ~30min 1on1 with Simon Technical Challenge (~4 hours) - Use AI, Google, or anything else you need. There are no rules - we care about the result, not the method. In-office meet & greet (1-2 hours) Following the initial phase, you’ll receive a one-month contract with a possibility to extend it indefinitely. We keep feedback honest and frequent, so you'll always know where you stand. Benefits 1. You’ll learn a lot Steep learning happens outside of your comfort zone. If you’re eager to learn, it means you’re hungry for uncertainty and discomfort. We only hire people like that. We promise to push you out of your comfort zone and give you access to extract as much knowledge as possible from the environment we’ve created. 2. You’ll get rich A startup environment often feels like eating glass. And if someone decides to eat glass with us, they deserve their slice of the pie. That’s why besides equity, we also have profit share that aims to supplement the base salary with bonus. We aim to get everyone up to 25k USD/mo ASAP, and then beyond. Perhaps this will happen Q1 of 2027, perhaps a bit later, but we don’t plan to hire many people, so this is really not unrealistic or hopeful. Unlike most other startups and scaleups, at Curie you do not have to wait for 10yrs for the equity to actually be worth something. We want to work with people who actually want to work hard, and that means getting everyone to be very financially independent as soon as possible. Earning your first $1M means enduring $1M worth of pain, but if you’re up for it, we’re here for you. We don’t hire people that aren’t obsessive, so the main question shifts from if to when. 3. You’ll own your slice of the pie You’ve probably heard stories from big companies about "extreme ownership" that turned out to be capped by a manager. We don’t have managers, you are the one responsible. You’ll have the entire team’s trust. The only limit is business reality; we want to earn money, not just be around. 4. Unlimited PTO We don’t count. People roughly average 20 days off + holidays, but if you need to stretch that beyond you can. Use your judgment. 5. You’ll have our back Our work philosophy is somewhere between a research lab, where 9-5 doesn’t work, but 996 doesn’t either and that of a sports team during championships. We know how important hard work and practice is between the tournaments, as well as how important rest is to avoid injuries. We consider our culture to be self-selecting, so if you’ll like meeting us during the interviews and the trial, chances are you’ll love it here. It should feel like a steal You’ll join a team of experienced venture builders to create the next massive success. In your first six months, you’ll learn more - while getting paid - than you have in the last few years combined. You will be trusted, respected, and heard. If it doesn’t feel like a steal for you, it’s probably not be what you’re looking for at the moment.
