The Role

We’re looking for Senior or Lead Software Engineers who want to:

• Ship product directly into the hands of the business user.

You’ll be part of a lean, senior, fast-moving tech team that values:

• Operating at pace.

What You'll Do

• Build and ship new features across our tech stack, with end-to-end ownership,

• Adopt and experiment with AI productivity tools, bringing your ideas on how they can improve our engineering and product velocity.

What We're Looking For

• Experience shipping SaaS B2B software in production,

• Solid expertise in TypeScript, ideally full-stack (Node + React),

• Familiarity with PostgreSQL and cloud platforms (we use AWS),

• A problem-solving mindset paired with accountability; you thrive with owning the outcomes,

• You’re fast, pragmatic, and comfortable with ambiguity.

Technologies

• Frontend: React and Next.js for modularity and speed; TypeScript and Jest for e2e testing,

• Backend: TypeScript and Node.js to build APIs quickly with full control over routing, middleware, and request handling,

• Infrastructure: AWS (infrastructure as code), enriched with Amazon Bedrock for AI enablement,

• Database: Amazon RDS with PostgreSQL,

• CI/CD pipeline: Github Actions drive safe and automated deployments with fast feedback,

• Developer AI tooling: Claude, ChatGPT (research, debugging, review), Github Copilot (coding acceleration, reduced context switching).

Why Join Us?

• Join an ambitious team that wants to win and pushes each other to reach the best individual and team goals,

• Work with a modern stack (TypeScript, Node, React, Postgres, AWS) and grow into architecture leadership,

• Use cutting-edge AI tools like ChatGPT, Claude, and Cursor as part of your workflow,
