We're Rist Labs — a cofounding studio building ethical, AI-powered B2C products that matter. We partner with sharp founders and top talent to launch ventures that move fast, scale globally, and make a real impact.

We’re looking for a Senior Full-Stack Engineer who moves fast, owns outcomes end-to-end, and drives product decisions. You’ll build and evolve the product and stack behind Kodree — a subscription platform helping people gain hands-on skills via web & mobile (iOS/Android), scaling across Tier-1 markets.

Your focus: shipping new features, growth experiments, and key integrations; improving architecture and product quality; and stepping into a leadership path as the product and team grow. You will work closely with both product and marketing, developing a deep understanding of business performance, analytics, and traffic acquisition.

Who we’re looking for:

• A Senior Engineer focused on shipping fast, owning results, and making an impact 🖇️ See how we build here
• With a full-stack experience (NodeJS, Typescript, NextJS, GraphQL, PostgreSQL)
• AWS (Lambda, SQS, DynamoDB, S3, CloudWatch, etc)
• With the ability to tackle new things and seek unconventional, optimized approaches
• You have a mentorship mindset (readiness to teach and share knowledge)
• You own problems end-to-end, not just doing tasks
• You want to develop and see how your solutions directly move business metrics
• You set and expect high standards from yourself and others
• You are comfortable with English: Intermediate+

An additional advantage will be:

• Experience in analytics (launching a/b tests, tracking funnels) and tooling (Amplitude, Airtable, Looker, etc)
• Experience in React Native (or willingness to learn mobile app development)
• Docker + Kubernetes

What you’ll do:

• Own Kodree’s product and tech stack
• Ship features across web and mobile app (React Native): product features, integrations, growth experiments
• We ship daily or several times a day - 🖇️more in the article, so you can instantly see the impact of your code
• Ensure your code quality, as we operate without a dedicated QA team
• Build and maintain integrations for marketing automation and analytics (Looker, Airtable, Meta / Google ads, Amplitude, Growthbook, Customer.io, etc.).
• Drive technical excellence and mentor a junior developer
• Collaborate directly with the CEO, product, design, and marketing teams

Tech stack

• Frontend: Next.js (TypeScript), GraphQL
• Mobile app: React Native (Typescript)
