Founding engineer roles building the first product at early-stage startups.
Software Engineer
Builds software for AI-driven metal 3D printing factories, focusing on controls, high-speed data pipelines, and geometry processing to automate industrial-scale manufacturing.
Software Engineer (New Grad December 2026)
Develops software for autonomous metal 3D printing factories, focusing on real-time controls, high-performance computing (GPU/FPGA), and geometry processing pipelines to enable scalable, automated manufacturing.
Software Engineering Intern (Summer 2027)
Summer 2027 software engineering intern at Freeform, helping build the core software behind its autonomous metal 3D printing factories — controls, high-rate data acquisition, and geometry-to-print-instruction pipelines. Hands-on software/hardware work primarily in C/C++ or Rust at an on-site Hawthorne (Los Angeles), CA facility.
Software Engineer (New Grad Summer 2027)
Builds software for AI-native metal 3D printing factories, integrating controls, high-speed data pipelines, and geometry processing to automate industrial-scale manufacturing.
Senior AI Systems Engineer
Designs automated systems where AI agents detect, investigate, and resolve production issues end to end without human intervention, converting manual engineering workflows into agent-run loops. Works with Python, TypeScript, AWS, and frontier LLMs at a small venture-backed AI startup.
Ground Station Software Engineer
Owns the Python and Go software that forms the communications backbone between ground stations and Cowboy Space's satellites — designing distributed systems, building simulation and testing frameworks, integrating with hardware, and supporting on-orbit operations for a space-based solar energy startup.
Finance Systems Engineer
Teton, a health-tech startup building an autonomous operating system for senior care, is hiring a Finance Systems Engineer in Copenhagen. The role owns the finance function's systems and data: building integrations between accounting, ERP, CRM, and internal product systems, automating workflows, and establishing data-integrity and reconciliation controls.
Software Engineer (All Levels)
Builds AI-driven data pipelines and tools for mineral exploration, embedding with geologists to solve ambiguous problems in geospatial data and field operations using Python, Django, React, and AWS.
Senior Software Engineer, Decision Science
Builds AI-driven decision-science tools for mineral exploration, optimizing discovery of lithium, copper, and cobalt to accelerate the energy transition. Focuses on scalable Python-based systems, MLops, and collaboration with geologists to process noisy geospatial data and deploy models in the field.
Thermal Systems Engineer
Own the thermal architecture and system-level thermal models of C12's cryogenic quantum computers: modeling heat loads across dilution-refrigerator stages, defining thermal budgets, running validation experiments, and guiding hardware design decisions with physicists and engineers.
Software engineer, cloud infrastructure
Builds and operates the cloud infrastructure behind Watershed's enterprise sustainability platform — owning compute, databases, networking, deployments, and observability. The work mixes platform reliability and developer-experience improvements with security, cost efficiency, and 24/7 on-call; Kubernetes, Terraform/IaC, and a major cloud provider (GCP helpful) are core.
Senior Software Engineer - Vehicle Motion Planning & Control
Build and implement motion-planning and control algorithms in C++/Python to guide autonomous vehicles safely through dynamic environments, from highway driving to complex urban scenarios.
Application Developer - Power BI React
Application Developer at a London AI customer-growth analytics firm: keep existing Power BI/DAX reports running while building the new AI-enabled web application layer (front and back end, React) that replaces them, migrate clients across, and work with client IT/security teams on deployments. £75,000, Holborn office, on-site Monday to Thursday.
AI-Powered App Developer: Power BI & React
An application developer at Morela, an AI analytics business in London, who maintains existing Power BI reports while building a new AI-enabled web application layer (React) and migrating clients onto it. Based in Holborn four days a week on a senior, lean team.
Software Engineer, Growth
Full-stack engineer at a residential battery/power company who owns the growth products end to end — running experiments across the sign-up, ads, and referral journeys, and building the experimentation infrastructure and data pipelines behind them. Work centers on modern web apps, APIs, and data models.
