About this role

Fleetcraft’s mission is to enhance humanity’s access to the sky. We’re building AI systems to make it dramatically faster and more affordable to maintain and certify aircraft - accelerating safety, reliability, and innovation across aerospace.

We raised an oversubscribed $3.2M seed round from top-tier investors (Susa Ventures, Liquid 2, EF, & Transpose Platform) and aviation experts, including some of the world's largest aerospace companies.

We're growing fast and looking for an exceptional full-stack founding engineer to join our team.

Why Join Us?

We’re building at the intersection of aerospace and AI — modernizing one of the world’s most complex and critical industries.

• Solve real-world problems: Your code won’t just ship; it will define how aircraft are inspected, maintained, and trusted worldwide.
• Join from the start: We’re growing fast and already working with some of the largest aviation companies in the world. You’ll be here from day one, helping shape the future.
• High trust, high ownership: Make decisions that move the whole company forward. We value autonomy, speed, and impact.
• Cutting-edge stack: Build with modern tools — Python, FastAPI, TypeScript, LLMs, MLOps — on high-stakes, real-world problems

What We’re Looking For

• 2+ years of software development experience
• Proven track record of building and shipping full-stack products in fast-paced, product-driven teams
• Hands-on experience building production AI systems with Python, PyTorch, and LLMs (OpenAI, Anthropic, etc.), integrated into real user workflows
• Familiarity with MLOps tools and CI/CD for both traditional and ML-driven systems
• Strong backend and API development skills — comfortable owning systems end-to-end, from data pipelines to user-facing interfaces
• Passion for building clean, usable products that solve real problems, fast
• Comfortable wearing multiple hats, challenging assumptions, and shaping product direction in ambiguous environments

Bonus Points

• Prior startup or 0→1 product experience
• Contributions to open-source AI/ML projects
• Experience with aviation, aerospace, or other safety-critical domains

You Should Apply If...

• You love building real products that users depend on — not just prototypes
• You’re excited about AI/LLMs but care more about how they’re applied than how they’re hyped
• You’re energized by fast feedback loops and high-leverage work
• You want to work close to users and shape what gets built
• You thrive in ambiguous, high-trust, high-ownership environments
• You’re looking to join a tight-knit early team, and help shape the company, not just the code

You Should Not Apply If...

• You prefer clearly defined tasks over autonomous problem-solving
• You need layers of process or structure to be effective
• You’re uncomfortable working in a fast-moving, high-ambiguity startup environment
• You’re focused primarily on research or academic work over production impact
• You avoid owning outcomes end-to-end — from design and implementation to iteration and support
• You’re looking for a large team with established roadmaps and guardrails

Tech Stack

• Core: Python, FastAPI, TypeScript, React
• AI/ML: OpenAI, Anthropic, computer use, evals, voice agents
• Infrastructure: Azure, Docker

Process:

1. Talent Screen (30 min video call)

2. Hiring Manager Interview (30 min video call)

3. Take-Home Test (1h45 on HackerRank)

4. Technical Review (30 min video interview with CTO)

5. In-Person Interview
