[Hiring] Senior Fullstack Engineer @Natter

Role Description

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

Qualifications

• 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
