Crosby Member of Technical Staff, Infrastructure at Crosby owns defined product surfaces end to end, working across data models, backend services, APIs, and user interfaces. The role involves building AI workflows, designing systems for complex legal workflows, rapid prototyping, and mentoring engineers.

Responsibilities

As a Product Engineer at Crosby, you'll own defined surfaces of the product end to end. You'll work across the stack — data models, backend services, APIs, and the interfaces our users work in every day — and go deep on the complex legal and AI workflows that sit underneath.
You'll partner closely with product, design, and our in-house legal team to shape what we build and how it works. Beyond shipping features, you'll set patterns, make foundational technical decisions, and help raise the bar for engineering as we scale. If you want to own real scope and ship fast, this is the role.
Build end to end: Design and ship features across the stack, from Python services and APIs to the React and TypeScript interfaces on top of them
Work on AI workflows: Build and improve the AI systems the product runs on
Design the systems: Model complex legal workflows into the data models, services, and APIs the rest of the team builds on
Prototype and iterate fast: Work closely with product and our in-house legal team to rapidly prototype and iterate on features
Grow the team: Mentor and help recruit world-class engineers

Qualification

ExperienceSystems thinkingProduct senseBuilder mindsetOwnershipCollaborativeCuriosity

Required

Experience: 5+ years building production software, with real backend depth and enough frontend fluency to ship a polished interface without waiting on a handoff. We work in Python and TypeScript but we care more about judgment than a specific stack
Systems thinking: You're comfortable designing schemas, APIs, and services that other engineers depend on, and you think about failure modes before they reach users
Product sense: You have strong instincts for what to build and a low tolerance for experiences that technically work but feel bad to use
Builder mindset: You're excited to create and scale systems from the ground up and make foundational technical decisions
Ownership: You take full responsibility for projects from ideation through execution and delivery
Collaborative: An effective communicator who works well with product, design, and domain experts
Curiosity: Passionate about learning and experimenting with new technologies to solve hard problems
