About Code Metal

Code Metal: Verifiable, AI-enabled code translation. For companies doing edge development, code portability, and code modernization across industries like automotive, defense, semiconductors, and aerospace. Speed time-to-market, meet safety and compliance... Backed by Accel.

About the role

Our Modeling & Simulation team is building the next-generation wargaming and decision-support platform that helps the DoW make multi-billion-dollar force-design decisions before those decisions are made in the real world. The team spans simulation and physics, backend and data systems, frontend and geospatial visualization, and AI systems, working together to turn operational questions into extensible, mission- and campaign-level simulations that government users can trust.

What they're looking for

  • Extensive professional C++ development experience, or equivalent experience, building performance-critical production software
  • Significant experience in commercial game development, game-engine development, or a similarly performance-constrained real-time environment
  • Experience shipping at least one commercial game, engine, platform, or interactive real-time product
  • Demonstrated ownership of foundational engine systems rather than primarily gameplay features, scripting, tools, or application-level integrations
  • Experience building or substantially extending a physics engine, game engine, simulation runtime, ECS, job system, or comparable core technology
  • Expert command of modern C++, including object lifetimes, ownership, templates, concurrency, synchronization, profiling, and low-level debugging
More about this role

Code Metal is the leader in automated software engineering you can trust. As AI writes more of the world's code, the bottleneck in software has shifted from writing code to verifying it works, and AI cannot verify its own work with certainty. Code Metal takes a fundamentally different approach: constrain AI to what it does reliably, verify every step independently of the model using formal methods, and keep engineers in the loop on the decisions that matter. The result isn't code that probably works — it's code that is provably correct, with auditable proof. Customers including the U.S. Air Force, L3Harris, RTX, and Toshiba use Code Metal to modernize legacy code, optimize performance on real hardware, and move prototypes to production, fast. Founded in 2023 with offices in Boston and San Francisco, Code Metal is funded by Accel, Salesforce Ventures, B Capital, Smith Point Capital, J2 Ventures, Shield Capital, Overmatch, RTX, and others.
