Founding Engineer

Cambridge Compute Co (C3); Cambridge; On-site; GBP 60,000 - 150,000; Full time

Benefits offered by this job

Founding equity

Hybrid in Cambridge (3+ days/week)

Job summary

Cambridge Compute Co (C3) is building a global compute network for GPU workloads with a live product and first users. We are a Cambridge-based, early-stage company offering equity and a hybrid work setup in Cambridge.

The role is for an early engineer who will help shape engineering, product and culture from day one. You will expand our supplier network by creating a repeatable integration framework and plugins, improve the Go agent for reliable job execution, and develop routing to place

Qualifications

• 2+ years shipping production code to real users.
• Demonstrable AI workflows and systems built to multiply output.
• Experience with APIs, SDKs, and integration across suppliers.
• Strong systems background: distributed systems, cloud, performance.
• GPU, HPC, or research computing experience.
• PhD or research background in a computational field with software work.
• Exceptional performance in adjacent fields may outweigh direct experience.

Responsibilities

• Help shape engineering, product and company culture as an early hire.
• Expand supplier network by building a repeatable integration framework and plugins for GPU cloud connections to C3.
• Own reliable execution by improving the Go agent, job lifecycle, logs, mounts, recovery, and metering.
• Build intelligent routing to decide where workloads run based on GPU type, capacity, price, performance.
• Turn demand-forecasting models into production environments and data prep.
• Work on a Go CLI, on-machine agents, and a TypeScript control plane on Cloudflare Workers.
• Contribute to research publications if excited by that work.

Job description

Salary: £60,000 - 150,000 per year

Requirements:

• We require 2+ years shipping production code to real users; strong open source work also counts, and exceptional early-career engineers are welcome.
• We require demonstrable custom agentic workflows as evidence of AI leverage, including systems you have built and how they multiplied your output.
• We value experience with APIs, SDKs, and integration work where many suppliers are made to behave as one.
• We value a strong systems background, including distributed systems, cloud infrastructure, and performance.
• We value experience in GPU, HPC, or research computing.
• We value a PhD or research background in a computational field with substantial software work.
• We hire hard-working, intelligent people, and exceptional performance in an adjacent field can outweigh directly related experience.

Responsibilities:

• We will have you help shape our engineering, product, and company culture from the beginning as one of our earliest hires.
• We will have you expand our supplier network by building a repeatable integration framework and plugins that connect each GPU cloud to C3.
• We will have you own reliable execution by improving the Go agent on each machine, including job lifecycle, streamed logs, mounts, failure recovery, and metered billing.
• We will have you build intelligent routing to decide where each workload runs based on GPU type, capacity, price, performance, and reliability.
• We will have you bring research into production by turning our demand-forecasting models into systems that prepare environments and data before jobs arrive.
• We will have you work on a Go CLI, on-machine agents, and a TypeScript control plane on Cloudflare Workers.
• We will have you contribute to novel scientific research and publications if you are excited by that work, although it is not required.

• Cloud
• Network
• TypeScript
• AI Agents
• API
• DevOps

More:

We are C3, also known as Cambridge Compute Co, and we are building one global compute network for GPU workloads so researchers and automated agents can access frontier compute more easily. Our system turns fragmented GPU capacity across many suppliers into one programmable platform that finds suitable GPUs, reproduces environments, positions data, routes work by availability, price, and performance, and meters only the time jobs are running. We are a Cambridge-based, early-stage company with a live product, first users, and a $5M pre-seed raise. We offer a full-time, permanent role with founding equity, a salary of £60,000 to £150,000 depending on experience, and a hybrid setup with at least three days a week in person in Cambridge. You will join a small founding engineering team, report to the founder, and work closely with the founder and our first engineer. We review applications on a rolling basis, move quickly, and are keen for the right person to start as soon as possible.
