Python Software Developer jobs in United Kingdom

At Basis, we’re not just building a company — we’re building the future. We’re redesigning the electrical systems that power our homes to fight climate change, reduce household costs, and create a better future for generations to come. That means rethinking everything, not just what we build, but how we build it.

To do this, we need incredible people. People who are bold, creative, sharp, and thoughtful. People who care. People who move fast and think differently. That’s where you come in.

We're looking to grow our Embedded Software Team in Christchurch. In the role of Embedded Software Engineer, you'll be helping us extend our capabilities with your excellent software skills and ownership. We have a product in market, real customers depending on our system, and a wealth of telemetry and feedback flowing in - now we need to make it even better.

You’ll be working with real‑world data from deployed systems, shaping improvements based on actual customer feedback and field reports, and expanding features we’ve delivered in early form. This is a highly complex distributed IoT system - interfacing cloud‑connected systems containing complex processing, configuration, and control. If iterating on a live product with tangible impact sounds exciting to you, keep reading.

Some of the things that you might be involved in include:

• Design & Implementation: Designing and writing embedded software across real‑time, distributed, and IoT systems.

• Hardware Integration: Collaborating with hardware and systems teams to integrate, validate, and debug across the full stack.

• Technical Problem‑Solving: Investigating issues, making tradeoffs (performance, memory, safety, user experience), and delivering solutions within constraints.

• Security & Compliance: Ensuring software meets regulatory and security requirements throughout development.

• Testing: Developing and maintaining unit test frameworks including continuous integration systems.

• Systems Test: Supporting the wider team and systems integration processes with full system HIL test frameworks.

• Code Review: Reviewing code written by Basis peers to ensure quality, collaboration, and conformance.

We think you’ll be a fit for this role if you have the following skills/or traits:

• Embedded software development with C/C++ and an RTOS

• A background in safety‑critical or regulatory‑compliant software development

• Real‑time sensor integration and signal processing

• Using Python for telemetry analysis, automation, and root‑cause investigation

• Low‑level communication protocols (e.g., SPI, UART, I2C)

• Hardware debugging and collaboration with electronics teams

• A tertiary qualification in electronics, mechatronics, software development, or equivalent experience

• An ability to take initiative, follow through on what you say you’ll do, and own your mistakes

• Comfort with uncertainty and using your initiative to solve problems

• Effective at working within a cross‑discipline team

• Judgement on when to move fast vs when to be thorough

Research shows that while men apply for jobs when they meet ~ 60% of the job criteria, women and other marginalised groups tend to apply only when they check every box. So if you think you have what it takes, but are not sure you check every box, we still want to hear from you 🙌

• A competitive salary and employee share scheme (ESOP)
• Unlimited annual leave so that you can take the time that you need to re‑energise
• Tools of trade, including laptop and headphone allowance
• Flexible hours — we focus on outcomes, so adjust your day around whānau, hobbies, or other commitments.
• A schedule of fun team events throughout the year (Lego Battlebots, table tennis, themed Friday drinks, and more!)
• Office dogs + steady supply offresh fruit and snacks in the office Access to Clearhead, our well‑being programme which gives you 5x free sessions with a psychologist per year
• A commitment to diversity and inclusion: Pride Committee and partnering with Pride Pledge, DEIB Committee, EEO Policy and well‑being strategy!
• Parental leave policy that tops up wages to 100% for the primary caregiver for up to 22 weeks and up to 6 weeks for secondary caregivers (conditions apply)
• The opportunity to learn and develop from some of the best and brightest minds in the industry!
