Architects FieldAI's robotics software platform — APIs, middleware, and runtime systems — so its foundation-model autonomy runs portably across legged robots, ground vehicles, and humanoids with real-world performance and reliability. Core stack: modern C++, Python, ROS 2, distributed middleware, and edge Linux performance engineering.
Senior engineer on GitLab's Authorization team owns the permission system deciding what users, tokens, and agents can access across GitLab. Day to day: building fine-grained token permissions and custom roles in the Ruby on Rails monolith, hardening GraphQL/REST enforcement, and migrating to a Rust Zanzibar-style policy engine over gRPC.
The Security Engineer will manage vulnerability assessments, incident response, and cloud security posture to protect the company's digital infrastructure and IoT medical devices. The role involves hands-on security engineering, CI/CD pipeline integration, and facilitating tabletop exercises using tools like Python, Splunk, and cloud-native security services.
Builds software that controls and scales spacecraft and ground infrastructure — flight software interfacing with hardware, simulation/testing frameworks, mission control, and internal tooling. Works across the stack with hardware teams, using languages like C++, Python, or Rust at a space-based solar energy startup.
Senior software engineer building high-reliability flight, mission, and ground software (C&DH, FDIR, secure comms) plus simulation and hardware-in-the-loop tools for a space-based solar power and orbital compute platform. Core stack is systems-level C++, Rust, and Python, working on-site in San Carlos, CA.
Cowboy Space is hiring a Firmware Engineer in San Carlos, CA to own embedded firmware for spacecraft subsystems end to end — writing C/C++ for microcontrollers and FPGAs, building low-level drivers and real-time control systems, and supporting board bring-up and hardware-in-the-loop testing for its space-based solar power platform.
Build and improve Lucenia’s distributed indexing and query engine in Java/Rust, contributing to open-source search technology and collaborating with a global team on data structures, algorithms, and low-level optimizations.
Lead a small team of embedded engineers building safety-critical firmware in C/C++ and Rust that controls actuators and processes high-speed signals for uranium enrichment industrial systems.

Systems Engineer on PDQ's PDQ Connect and SmartDeploy teams acting as a Tier 3 escalation point: investigating and reproducing complex customer issues across Windows endpoints, cloud services, and APIs, then partnering with engineering, QA, and product to validate fixes. Stack includes Elixir, Rust, C#, AWS/GCP, SQL, and PowerShell/Python.
Backend engineer at Kalshi Trading building and maintaining the trading infrastructure behind its prediction-market trading operations: order management, high-performance event-driven systems, and APIs. Core stack includes Golang/Rust/C++, Postgres, and AWS (RDS/ECS).
Build and deploy deep learning models for space-based electro-optical image processing to support defense and intelligence missions.
Senior flight software engineer who owns payload flight software for Cowboy Space's satellites — writing Rust for attitude/pointing state machines, command handling, and telemetry/data storage, setting the team's architecture, building HIL/simulation test infrastructure, and driving toward a near-term on-orbit demonstration. On-site in San Carlos, CA or Kent, WA.
Builds and tests the software behind Cowboy Space's spacecraft and ground infrastructure: flight software with real-time hardware control, simulation and hardware-in-the-loop test frameworks, and mission operations tooling. Core stack spans C++, Python, and Rust on Linux in a fast-paced aerospace startup.
Leads the embedded software team building real-time, fault-tolerant flight software for satellites that collect solar power in orbit and beam it to Earth via infrared lasers. Day to day: mentoring engineers, planning firmware releases, architecture and code reviews, avionics hardware integration, and SITL/HITL testing, primarily in C/C++/Rust on embedded Linux.
Staff Software Engineer building, maintaining, and evolving GitHub Copilot AI Models' robust, scalable platform, ensuring consistent, performant, and safe access at scale.
