Software Engineer (Power Systems)

Job Description

Our vision

AI + data centers are booming, electrification is accelerating, and trillions in + storage projects are queued — but the real bottleneck is the grid. Grid planning and operations are now a -scale systems problem: complex models, messy data, strict governance, high-stakes decisions.

What is Squid

Squid is building the agentic fabric layer for grids — where truth lives, change is tracked, and humans + AI agents can safely operate together. We unify legacy planning models and operational data into a versioned, auditable source of truth, then layer on collaboration + AI agents that help teams run checks, explain changes, and move faster — without losing rigor. We’re less than 3 months old and already working with one of the largest grid operators globally.

The role

You’ll use power systems knowledge to build better software — and help us ship bespoke modelling capability for real grid workflows (planning, analysis, connections). You’ll work directly with the founders and the early team, be customer-facing, and ship end-to-end (prototype → production → iterate).

We’re AI- in how we build: expect high agency with tools like Cursor / Claude Code, agent-assisted QA, and “agent-first, human-in-the-loop” development — alongside real engineering across backend, cloud, and data systems.

You’ll thrive if you have some of this

  • Power systems modelling experience (industry or research): load flow, short circuit, contingency studies, network model building, etc.
  • Familiarity with tools like pandapower, PyPSA, GridCal (or similar open-source stacks), and/or commercial tools like DIgSILENT PowerFactory, IPSA, PSS®E
  • Experience with grid connections studies or utility workflows is a big plus
  • Software engineering experience can vary — if you’re sharp and curious, we can ramp you fast

What we care about

  • You love power systems and want to go deep (this is not a “learn it later” domain)
  • You’re excited to turn messy real-world grid workflows into reliable product
  • You move fast, take ownership, and like being close to customers
  • You’re excited about pushing AI tooling to the limit to ship high-quality work faster

What do you include in the application (via form/CV)

  • Expected salary range / notice period
  • A short note on your power systems background (projects, studies, tools you’ve used)
  • Links or examples (GitHub, papers, models, studies, anything you’re proud of)
  • Tell us if you have the right to work in the UK

Join us in our brand new office in Paddington, where you will have full autonomy day-to-day.

Please include your expected salary range at the top of your application. Applications open until early April 2026. Interviews soon after.
