Senior Python Software Engineer
Up to £75,000 | Hybrid | Equity
Method Resourcing are working with a fast-growing technology business, who are scaling their engineering function following significant investment, multiple acquisitions, and continued international expansion.
Over the last 12-18 months they've grown rapidly across Europe, expanding both their engineering capability and product offering. All whilst supporting millions of critical events every single day for customers operating in sectors where reliability isn't optional.
Their technology underpins life safety, security, critical infrastructure, and IoT solutions, where reliability isn't just important, it is critical.
The Opportunity
They're undertaking a major engineering transformation, decoupling a monolithic platform into modern, scalable services on Azure.
You'll be joining a dedicated Signalling Engineering team responsible for designing and building the systems that power the heart of the business.
You'll help build highly resilient APIs and backend services capable of processing millions of signalling events every day, whilst modernising legacy architecture into loosely coupled, cloud-native services that are easier to scale, maintain, and evolve.
This isn't a role where you'll spend months fixing bugs in a legacy codebase. You'll be helping shape the next generation of the platform while solving the kind of scaling and reliability challenges that don't exist in smaller engineering teams.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You'll Be Doing
- Building scalable backend services using Python
- Designing robust, secure APIs powering critical customer-facing systems
- Breaking down and modernising legacy applications into distributed services
- Working on systems processing millions of events every day with high availability requirements
- Writing clean, well-tested, maintainable code following engineering best practice
- Participating in architecture discussions and technical design
- Mentoring engineers through code reviews and technical guidance
- Driving quality through testing, CI/CD, and continuous improvement
- Collaborating with Product, Delivery, and Architecture teams to deliver new features
What They're Looking For
They're looking for an experienced Software Engineer who enjoys ownership and solving complex engineering challenges.
You'll likely have experience with:
- Python
- REST API development
- Distributed systems or microservices
- SQL databases
- Cloud platforms (ideally Azure)
- CI/CD pipelines
- Test-driven development and automated testing
- Building scalable production systems
Experience modernising legacy applications or working within event-driven architectures would be particularly valuable.

Why Join?
This isn't a business standing still.
In recent years they've completed multiple acquisitions, expanded internationally across the UK and Europe, and continue investing heavily in both their products and engineering teams. Today they support customers across Fire, Security, Telecare, Critical National Infrastructure, Utilities, and Retail, delivering technology where uptime and resilience are critical.
You'll be joining a collaborative engineering culture where senior engineers are trusted to make technical decisions, influence architecture, and genuinely shape the future of the platform rather than simply delivering tickets.
If you're looking for a role where you'll work on meaningful technical problems at scale, whilst helping modernise a large production platform, I'd love to tell you more.
What's in it for you?
- Equity options
- Hybrid working
- 25 days holiday (as well as bank holidays)
- Private pension
- Dedicated learning & development budget
- Modern engineering culture with genuine technical ownership
- Cycle to Work & Green Car schemes
- Subsidised gym membership
- Employee rewards platform
- Annual volunteering day
- Life assurance
- Regular team socials and company events
