Due to progression, this role exists to replace a senior engineer within a well-established software company operating in the highly regulated energy sector.
The software you'll work on is business critical. It must be reliable, auditable, and able to stand up to regulatory scrutiny. That shapes how engineering is done here: considered design, well-tested code, and a focus on doing things properly rather than quickly.
If you're a Python engineer ready to take on more responsibility, mentor others, and work in an environment where engineering discipline matters, this role is designed for you.
What you'll be working on:
- Building and maintaining Python-based services and applications
- Writing clear, well-tested, and maintainable code
- Contributing to design decisions and agreed technical standards
- Reviewing code and helping raise engineering quality across the team
- Supporting reliable releases in a cloud-hosted environment
You'll report directly to a Principal Software Engineer and work alongside experienced engineers who value clarity, quality, and pragmatic problem-solving.
What 'senior' means here:
- Sound technical judgement
- Ownership of complex pieces of work
- Mentoring and supporting less-experienced engineers
- Leading by example in code quality, testing, and delivery
It's well suited to someone who may not yet hold a senior title, but is already operating at that level and ready to step up.
Essential experience:
- Commercial experience developing software with Python
- Experience building and maintaining production systems
- A strong approach to testing and code quality
- Experience working in a cloud environment (AWS)
Working pattern and location:
Hybrid role with 2 days per week onsite. Office location: Oxford.
Salary and benefits:
- Circa £56,000 base salary
- Bonus up to 15% (personal and company performance)
- 25 days' annual leave plus bank holidays
- Pension scheme (4% employer contribution when you contribute 5%)
- Health care scheme (including dental and eye care)
- EV car scheme (terms apply)
- Free onsite gym
- Employee Assistance Programme and wellbeing support
- Paid volunteering day each year
