Senior Software Engineer

We're looking for a Senior Software Engineer to join the team in Uxbridge that builds it.

What you'll actually do

You'll own features end to end — from design discussion through to release — across a stack that spans a mature .NET backend, Angular front ends, and Python tooling. Specifically:

• Design and build backend services and APIs that process large volumes of flight data, where performance and correctness genuinely matter

• Take technical ownership of a product area: make the architectural calls, and be the person the team asks about it

• Review other engineers' code and mentor two or three developers earlier in their careers

• Work with QA, product and the engineering lead across a normal Agile cycle — planning, standups, reviews, retros

• Help us modernise: we have a long-lived .NET codebase with some older Windows service components, and part of this role is bringing it forward sensibly rather than rewriting for its own sake

What we need

• Around 4+ years building production software commercially

• Strong C#/.NET and solid relational database skills (we use MySQL)

• Comfortable working across the stack — you don't have to be a front-end specialist, but you should be able to work in TypeScript/Angular when a feature needs it

• Experience designing and consuming RESTful APIs

• Genuinely good at debugging: the ability to work out why a system is misbehaving from incomplete information

• Git and modern version control workflows

Useful, but we'll teach you

• Python

• AWS (EC2, Lambda, S3, RDS)

• Docker and CI/CD pipelines

• Automated testing frameworks

• Aviation or aerospace domain knowledge — almost nobody arrives with this, and we don't expect you to

You do not need to tick every box. If you're strong on the backend and curious about the rest, apply.

What we offer

As part of the wider Teledyne UK group, we offer our employees a range of company benefits that include:

• Salary sacrifice-led pension plan that matches employee contributions up to 7%.
• Employee Stock Purchase Plan.
• Free life assurance cover at the value of four times basic annual salary.
• ⁠Salary sacrifice Electric & Hybrid Vehicle car scheme
• 25 days holiday per annum, plus bank holidays.
• Holiday purchase scheme which enables employees to purchase an additional 5 days worth of annual leave each year.
• Company funded medical cash plan (MediCash) which allows eligible members to offset the cost of routine medical treatments.
• Internal reward and recognition scheme linked to internal benefits platform.
• Employee Assistance Programme.
• Comprehensive wellbeing programme that supports employees with their physical, mental and financial health, as well as their cultural/environmental wellbeing.
• Competitive employee discounts platform that provides employees with discounts with leading brands/retailers.
• Cycle to Work scheme.
• Enhanced family-friendly benefits and policies.
• Company sick pay.
• Free Onsite parking
• Career development across the wider Teledyne group — a lot of our engineers have moved between teams, sites and disciplines
• Software that matters: what you ship affects how safely aircraft are operated

The commute, honestly

We're onsite four days a week with one day from home. We know that rules us out for some people. But if you live anywhere in West London, Hillingdon, Buckinghamshire or along the M4/M40, this is likely the shortest commute you'll find for a role at this level — Uxbridge is the end of the Metropolitan and Piccadilly lines, and there's parking. Several of our team took this job specifically to stop commuting into central London.

Interview process

• A Teams call with the hiring manager and site manager — informal, both ways

• An onsite session covering technical discussion and a paired programming task, plus competency-based questions with our Head of Digital Solutions
