👻 Ghost score 25%

What it means: how likely this posting is sitting open without active hiring.How to read it: 60% or higher means we think this is a ghost. Lower scores are less of a worry.How we score it: age, reposts, open roles vs team size, how fast jobs close, and whether pay is listed.Fine print: an estimate from public data, not a judgment of the company. Real jobs can score high, so treat it as a hint, not a fact.

Code Metal is a B2B software company that provides verifiable code translation and automated toolchains to convert high-level research/AI code into low-level, standards-compliant, production-ready software for mission-critical systems. It combines AI-guided translation, static analysis, automated test-generation (including MCDC), formal verification, and target-specific optimization to produce traceable, safety- and compliance-checked code (C/C++, Rust, VHDL, CUDA, OpenCL, etc. ) that can be deployed across chips and embedded platforms. The platform targets defense, aerospace, automotive, semiconductor and robotics customers who need guaranteed functional equivalence, safety compliance, and chip portability.

📋 Description

• Design and implement mission- and campaign-level simulation capabilities in modern C++ and Python • Build and extend event-driven, discrete-event, agent-based, and constructive simulation frameworks • Own event scheduling, simulation time, state transitions, platform abstractions, scenario execution, data collection, and deterministic replay • Develop models for platforms, sensors, weapons, communications, electronic warfare, jamming, command and control, logistics, and environmental effects • Extend AFSIM and comparable simulation environments through C++ plugins, framework services, SDK integrations, new platform types, and reusable model interfaces • Translate operational concepts, system specifications, and subject-matter expertise into maintainable software models with explicit assumptions and testable behavior • Modernize legacy campaign and mission-analysis tools and integrate them into a coherent simulation architecture • Build scenario-generation, Monte Carlo, sensitivity-analysis, campaign-execution, and evaluation workflows • Scale simulations across workstations, on-premises infrastructure, and cloud compute while preserving reproducibility and model provenance • Connect constructive simulations with distributed, operational, hardware-in-the-loop, or human-in-the-loop environments • Establish verification and validation practices, reference scenarios, regression suites, and quantitative measures of model credibility • Work directly with government, Air Force, and broader DoD stakeholders to understand acquisition questions and deliver usable capabilities • Collaborate with physics, backend, geospatial, AI, and product teams to integrate the simulation kernel into a larger interactive platform • Lead design and code reviews, mentor teammates, and improve architecture, documentation, testing, and release practices • Set department-wide quality and correctness standards, provide architectural guidance, scope major initiatives, lead architectural reviews, and mentor staff at scale

🎯 Requirements

• Five or more years of professional software-development experience building simulation, autonomy, robotics, game-engine, digital-twin, or similarly complex systems • Principal level expectation: 10+ years of experience • Strong production experience in modern C++, with proficiency in Python for tooling, orchestration, analysis, or automation • Hands-on experience developing or extending a simulation framework • Experience with event-driven, discrete-event, agent-based, constructive, or distributed simulation architectures • Ability to represent complex real-world entities, interactions, rules, and edge cases as clear software abstractions • Experience building plugins, SDKs, reusable model interfaces, framework services, platform types, or similar extension mechanisms • Strong understanding of software architecture, data structures, algorithms, APIs, testing, debugging, and performance engineering • Experience making substantial changes within a large existing codebase while maintaining ongoing delivery • Experience with model verification, validation, calibration, or regression testing • Ability to turn ambiguous operational or technical requirements into executable engineering plans • Strong written and verbal communication skills, including documenting model assumptions, limitations, interfaces, and intended use • Bachelor's degree or equivalent experience in computer science, engineering, applied mathematics, operations research, physics, or a related discipline • Active Secret clearance or eligibility to obtain one • Strongly preferred: direct AFSIM experience; behavior trees, finite state machines, and PDDL; Air Force, Space Force, joint, or broader DoD acquisition and mission-analysis experience; sensor, weapons, electronic warfare, jamming, communications, logistics, or command-and-control modeling; legacy system modernization into C++; simulation framework or campaign system design; familiarity with HLA, DIS, OneSAF, JSAF, NGTS, STK, or other simulation environments; operational and constructive simulation experience; active TS/SCI clearance • U.S. work authorization may be required for certain project assignments involving security clearance

🏖️ Benefits

• 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 • Pay strives to be at the upper end of the salary range
