Responsibilities

Own features end-to-end across the software development lifecycle: from problem framing and architecture through implementation, test, deployment, and operation

Build and maintain the platform services (real-time data pipelines, orchestration, UI, alerting), automation tooling and languages, and device-level software used by teams across the company to control and monitor real hardware

Partner directly with hardware, test, manufacturing, and launch teams to design, instrument, and continuously improve automation and control systems that are safe, observable, and resilient in production environments

Qualification

C++RustCompiler designReal-time systemsAutomation frameworksPerformance optimizationCollaborationProblem solving

Required

7+ years of experience in systems programming (C++ or Rust) and/or programming language implementation, with strong fundamentals in compilers, interpreters, or virtual machines

Built or extended domain-specific languages or execution engines for hardware automation, scientific computation, trading, or other real-time domains where correctness, latency, and memory footprint matter

Comfortable designing fast, low-allocation code paths and reasoning about performance in terms of cache behavior, allocation patterns, and data layout

Excited to work on a proprietary language used for live hardware control and calculations, and to collaborate closely with users to evolve the language and runtime in a safety-critical context

Preferred

Academic or industry background in compilers, static analysis, formal methods, or programming languages research

Experience implementing type systems, bytecode interpreters, JITs, or code generation pipelines optimized for low latency and small memory footprints

Experience building scriptable automation frameworks or configuration/DSL layers on top of C++/Rust systems used to orchestrate hardware, tests, or complex workflows

Familiarity with real-time scheduling, concurrency models, and fault-tolerance techniques used when a language or runtime is responsible for controlling physical equipment
