About the role

About the Role

What You’ll Do

  • Take concepts from zero to a working product and real-world validation
  • Own full-stack development: frontend, backend, APIs, and data layers
  • Shape product direction alongside venture leads and PMs, not just execute against specs
  • Design and build rapid validation loops to test assumptions and de-risk ideas early
  • Architect and implement core systems, models, and integrations from scratch
  • Use AI as a force multiplier across development and product capabilities
  • Make deliberate tradeoffs between speed and durability based on venture stage
  • Operate effectively with incomplete, evolving, or imperfect inputs to get to working solutions quickly
  • Work directly with stakeholders to validate workflows and refine solutions
  • Identify and mitigate technical and product risks early
  • Contribute across multiple ventures, applying patterns and learnings to accelerate future builds
  • Maintain a high bar for technical quality while moving with urgency

How You’ll Operate

  • You move fluidly across the stack and don’t rely on narrowly defined ownership boundaries
  • You turn unclear ideas into concrete implementations without waiting for full direction
  • You know when to prioritize speed and when to invest in structure
  • You bias toward action – building, testing, and iterating to create clarity
  • You’re comfortable abandoning approaches that don’t show signal and redirecting quickly
  • You think in terms of outcomes and user impact, not just technical output
  • You can context switch across multiple problems without losing momentum

You Should Have

  • 6+ years of software engineering experience, including time in early-stage 0→1 environments
  • Proven ability to build and ship full-stack applications end-to-end
  • Strong judgment around speed vs scalability tradeoffs in early-stage systems
  • Demonstrated use of AI to accelerate development or product capabilities
  • Comfort operating in ambiguous environments where both the problem and solution are evolving
  • Ability to work with incomplete or messy inputs to arrive at practical solutions
  • Strong communication skills and the ability to influence decisions

What Sets You Apart

  • You’ve operated in environments where there was no clear playbook
  • You’re comfortable owning entire systems rather than components
  • You identify leverage – reusable patterns, shortcuts, and ways to move faster across efforts
  • You focus on building things that work in real-world conditions, not just ideal ones
  • You take responsibility for outcomes, not just implementation

This Role Is Not For You If

  • You prefer strictly defined ownership (frontend-only, backend-only, etc.)
  • You need well-defined requirements and stable roadmaps
  • You want to focus on maintaining and scaling existing systems
  • You rely on structured environments to do your best work
