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.

We are hiring a UX Lead / Senior Product Designer who will own the end-to-end design experience for mission critical platforms— translating complex geospatial, simulation, and mission-data workflows into interfaces that operators, analysts, and engineers can actually use. ## The Role This product operates at the intersection of high-fidelity simulation, geospatial data, and real-time decision-making — environments where poor UX has direct operational consequences. We're looking for a UX Lead who can take dense, domain-specific requirements from operators, engineers, and mission planners and turn them into clear, performant, and intuitive workflows. This is not a pixel-pushing role. You will function as a peer to the Product Manager — shaping how the product works, not just how it looks. You will conduct user research with hard-to-reach domain experts, run design sprints, own the design system, and ensure the frontend team has clear, implementable specifications to build against. ## Responsibilities - Lead end-to-end UX for a complex, data-dense geospatial and simulation platform — from early concept through production-ready design specifications. - Conduct user research with domain experts including operators, analysts, and mission planners. Surface mental models, workflow requirements, and pain points that users may not be able to articulate directly. - Translate highly technical, domain-specific requirements into clear interaction patterns, information architectures, and user workflows. - Build and iterate on prototypes (low to high fidelity) in close collaboration with the Product Manager — moving quickly from concept to testable artifact. - Own the design system. Define and maintain consistent, implementable UI standards that the frontend engineering team can build against with confidence. - Partner closely with frontend engineers to ensure design intent is executed correctly. Participate in implementation reviews and catch fidelity gaps early. - Facilitate design reviews and research readouts with technical and non-technical stakeholders — including engineers, product leads, and customer teams. - Manage and mentor UI/UX Designers and Researchers as the team grows, setting quality standards and design process. - Contribute to product strategy. Bring user insight into roadmap conversations and advocate for decisions grounded in research, not assumptions. - Document design decisions and rationale to support cross-functional alignment and institutional knowledge. ## Requirements - Strong user research skills — proficiency in interviews, contextual inquiry, usability testing, and synthesizing findings into actionable design direction. - Demonstrated experience designing data-dense or geospatial interfaces — maps, dashboards, operational displays, or similar complex information environments. - Proficiency in Figma, including prototyping, component libraries, and design system management. - Ability to work in ambiguous, domain-heavy environments where users cannot always articulate what they need — comfort turning incomplete requirements into clear design hypotheses. - Excellent communication and facilitation skills. Able to run a design review or research readout with engineers, PMs, and customer stakeholders equally effectively. - Experience working closely with a Product Manager as a peer — contributing to product thinking, not just executing on specifications. - Strong written communication skills for documenting design rationale, research findings, and workflow logic. - Comfort operating with high autonomy in a fast-moving environment with evolving requirements. - Eligible to obtain and maintain an active U.S. security clearance. ## Preferred Qualifications - 5+ years of experience in UX design, product design, or human factors engineering. - Experience designing for defense, aerospace, government, or other mission-critical software environments. - Familiarity with military operator workflows, mission planning interfaces, or command-and-control systems. - Experience designing for or within classified environments (SCIFs, air-gapped networks) where standard tooling and collaboration methods may be restricted. - Understanding of accessibility standards in operational or low-light environments. - Exposure to frontend engineering concepts (React, component libraries) sufficient to communicate implementation constraints with engineers. - Active U.S. security clearance (Secret or Top Secret). - Experience building or scaling a design system from early-stage to production. ## Benefits - Pay depends on experience, but we strive to be at the upper end of the salary range - Health care plan with 100% premium coverage, including medical, dental, and vision - 401k with 5% matching - Paid Time Off (uncapped vacation, plus sick and public holidays) - Flexible hybrid or remote work arrangement - Relocation assistance for qualifying employees Wage Transparency - The salary range for this role is not a guarantee of compensation or salary, as the final offer amount may vary based on factors including, but not limited to, individual proficiency, skills, experience, and location. We are an equal opportunity employer. US Citizenship may be required for certain project assignments involving security clearance. Pursuant to the San Francisco Fair Chance Ordinance, we will consider for employment qualified applicants with arrest and conviction records. ## About Code Metal ## Company Overview - **One-liner**: Code Metal provides an AI-powered platform for verifiable code translation, enabling mission-critical industries to safely move software to different hardware architectures and languages with formal verification. - **Entity Type**: Private (Series B) - **Headquarters**: Boston, Massachusetts, United States - **Founded**: 2023 - **Founders**: Not publicly disclosed ## Core Business - **Primary industry/industries**: Software development tools; defense, automotive, aerospace, robotics, logistics - **Target customers**: B2B enterprise – engineering teams in safety-critical sectors (defense, automotive, aerospace, medical devices) - **Mission or purpose statement**: "Make AI trustworthy by safely delivering the last mile for mission critical industries" ([codemetal.ai](https://codemetal.ai/)) ## Products & Services - **Verifiable Code Translation Platform**: An AI-driven tool that automatically translates source code to a target architecture/language while generating a full test suite (functional and MCDC coverage) and formally verifying functional equivalence.
