We partner with some of the world’s largest and most complex enterprises (Fortune 500 and equivalent), and are currently growing our team from 30 to 60 employees.

The Role

We're looking for a Senior Fullstack Engineer who thrives on owning products end-to-end. You'll work across the entire stack, from shaping the user experience to designing the systems behind it. This is a high-ownership role: you'll contribute to product decisions, set technical direction, and build things that matter.

You'll be joining a small, high-calibre engineering team that values ownership and autonomy over bureaucracy. We care about writing clean code, building reliable systems, and shipping work we're proud of.

How We Work

• Everyone owns quality. We don't have a separate QA team: if you write it, you test it, and you ship it.
• We ship constantly. We rely on CI/CD, feature flags, and observability to get code to production multiple times a day. Fast feedback is how we learn and improve.
• End-to-end ownership. You'll touch everything from database schemas to React components to the AWS infrastructure that runs them. It's your work, but always with your team's support.
• We use AI to work smarter. Claude Code, Codex, and other tools help us handle the mundane so we can focus on the hard, interesting problems.
• Language isn't the point. We care more about engineering fundamentals than whether you know Python, TypeScript, or Rust.

What You'll Do

• Own features from conception through deployment: frontend, backend, and everything in between
• Design and build scalable APIs, data models, and backend services
• Build polished, performant user interfaces that feel great to use
• Collaborate closely with product and design to shape what we build, not just how
• Set technical standards and contribute to architectural decisions
• Participate in code reviews, help grow the team, and raise the bar on quality
• Identify and resolve performance, reliability, and security issues proactively

The Stack

• Languages: Kotlin, TypeScript, Python, Rust
• Frontend: React
• Data: Postgres, DynamoDB, Kafka
• Infra & Compute: ECS, EKS, Lambda
• IaC: AWS CDK

What We're Looking For

• 5+ years of professional software engineering experience, with strong fullstack ownership
• Proficiency across modern frontend and backend technologies (we use React and Node.js/TypeScript)
• A track record of shipping production-quality software in fast-moving, post-Series A environments
• Strong product instincts: you think about users, not just systems
• Comfort with ambiguity; you make decisive technical choices without a perfect spec
• Excellent communication skills; you can articulate trade-offs clearly to technical and non-technical teammates
• Experience with AWS and CI/CD pipelines

Bonus Points

• Experience working with AI/LLM-powered products
• Background in B2B SaaS or conversational/voice interfaces
• Experience in early-stage or high-growth startups

The Process

We respect your time. The process typically takes two weeks

• Screening Interview (30 mins)
• Take-home tech test (1-2 hours)
• Systems design session (1 hour)
• Final chat with the CEO
