Founding Engineer (US)

Build the AI platform that's rewriting a $50B industry

Salary range - $180-220k USD + Equity + Benefits

We're building one of the first agentic systems for enterprise legal and compliance teams that actually automates their manual work. End-to-end. Delivering 80% faster compliance reviews and 4x productivity gains.

We recently closed a $12M USD Series A (Peak XV Partners, DST Global, Airtree) and are growing fast in the US; building the infrastructure that will completely re-define how enterprises think about compliance.

Think Canva for design. Atlassian for projects. Haast for compliance.

Compliance is a $50B global challenge. Enterprise legal and compliance teams spend a significant amount of time manually reviewing documents against policy, spotting regulatory risk, and signing off on content before go-to-market. It's painful and it's mission-critical.

We're building the infrastructure that makes this manageable at scale. You'll be working on systems that directly reduce risk and unlock productivity for some of the world's largest organisations.

As our first US based Engineer; you'll be the technical bridge between our product vision and our customers' reality.

You're a full-stack engineer who thrives at the intersection of innovation and execution, building our platform while staying connected to the teams actually using it.

You'll split your time between heads-down building (shipping code that matters) and being engaged with customers, understanding their pain points firsthand, iterating on features in real-time, and using that feedback to shape our product direction.

You'll own end-to-end technical decisions: designing systems, shipping to production, and iterating based on direct customer interaction.

This is high-autonomy work. You'll collaborate directly with our founding team, move at startup velocity, and have genuine influence over both our architecture and product roadmap.

• Design, architect, and ship full-stack features that directly solve our customers compliance challenges

• Own the technical relationship with key customers; implementing solutions, gathering requirements, and translating feedback into product improvements

• Build scalable services and APIs that power our LLM compliance platform while keeping the customer experience front and center

• Make high-impact technical decisions quickly, knowing that you'll be accountable to both our engineering standards and our customers

• Challenge assumptions on "why" and "how", you'll directly influence what we build and how we build it

• Shape our product roadmap and engineering practices as we scale from Series A to market leadership

• You've built full-stack systems at meaningful scale; you're equally comfortable architecting backend services and shipping frontend code that customers interact with daily

• You're deep on one or more of: Go, Node.js/TypeScript, or Python, and you're fluent enough across the stack to own features end-to-end

• You understand APIs, distributed systems, and the tradeoffs between speed and reliability in production environments

• You genuinely enjoy working with customers; you're not just shipping features, you want to understand the human problem you're solving

• You've shipped in fast-moving environments and understand what it takes to move quickly without breaking things

• You're curious about how LLMs work and excited about building practical applications on top of them, not just the theory

We're looking for people who've shipped things they're proud of and want to work on a problem that genuinely matters.
