    Description
    Staff Engineer / API Lead - Mission-Driven AI Startup (New York City)Want to own the core APIs powering an AI product used by millions around the world? A fast-growing language learning startup (name currently under wraps ) is gearing up for a pivotal 2025 and needs a Staff Engineer / API Lead to architect, build, and scale the heart of their platform.If you're the kind of engineer who loves big technical challenges, thrives in high-output environments, and wants your work to have real human impact - this is the place.What You'll Do
    • Own the design and evolution of the company's core APIs, from architecture to implementation
    • Build scalable, reliable backend services that power real-time, AI-driven learning experiences
    • Lead technical direction across teams; set standards, review designs, mentor engineers
    • Drive platform performance, observability, cost optimisation, and cloud infrastructure decisions
    • Collaborate directly with product and engineering leadership to shape the roadmap
    • Stay hands-on: writing high-impact code, improving systems, and solving tough technical problems
    Why This Role Is Unique
    • You will literally own the backbone of the platform-the APIs that everything else relies on
    • Join during a defining hyper-growth phase where technical decisions have huge leverage
    • High autonomy, high trust, and the chance to influence engineering culture from the ground up
    • Direct collaboration with founders and engineering leadership
    • Mission-first environment focused on unlocking learning for kids everywhere
    What You Bring
    • 7-10 years of backend or distributed systems experience, ideally at scale
    • Deep expertise with AWS, including services, architecture patterns, and cost-aware design
    • Strong experience with Kubernetes, containers, and modern cloud infrastructure
    • Proven experience designing and scaling APIs (REST, GraphQL, gRPC-any production-grade interface)
    • Strong coding skills in Python, Go, or similar backend languages
    • Experience influencing or leading technical direction across teams
    • Startup-ready mindset: ownership, speed, and a bias for high-impact execution
    • Bonus: Familiarity or interest in Rust for systems-level or performance-sensitive components
    Who You Are
    • A strategic thinker who still loves writing code
    • Someone who enjoys architecting complex systems and making them elegant
    • A force multiplier-your impact makes the whole team faster and better
    • Comfortable in fast-paced, ambiguity-heavy environments
    • Drawn to mission-driven work where the results matter
    Location & Eligibility
    • Hyrbid in New York City (this role requires close collaboration with the founding and engineering teams)
    • Full US work authorization required (no sponsorship)
    If you want to build core systems, shape engineering standards, and see your work translate into life-changing tools for kids learning languages-this is the opportunity.
