Job title: Senior Developer – Backend C#

Salary: £70-80k
Grade: Band 3

Contract type: TfL Reference: 4623

Contract details: Permanent Location: Pier Walk, North Greenwich

Application closing date: 21/6/2026 at 23:59

External - All offers of employment are subject to satisfactory right‑to‑work checks. Candidates must be able to demonstrate their right to work in the UK. At the present time TfL is unable to offer visa sponsorship for this role.

Hybrid working within this role enables a balance of 50 per cent of time split between the office and home over a 4-week period. Hybrid working arrangements can evolve subject to business requirements.

You’ll influence the lives of millions

Join TfL to build elegant, high‑performance systems and APIs using modern practices, delivering scalable software relied on by millions every day.

You’ll work as part of a Scrum team, contributing to refinement, sprint planning, retrospectives, demos, and daily stand-ups. You’ll also collaborate with other teams in a scaled Agile environment to deliver coordinated, high-quality software.

You’ll play a key role in designing and delivering scalable, cloud-native solutions on Microsoft Azure, influencing architecture and helping shape engineering best practices across the team. We’re looking for someone who is passionate about building reliable, high-performing systems and continuously improving how software is delivered:

C# / .NET (Core)
Microsoft Azure (App Services, Functions, Service Bus, API Management)
RESTful Web API Design & Development
Azure DevOps (CI/CD – YAML Pipelines)
Infrastructure as Code (Bicep / ARM)
SQL Server and data management
Test-Driven Development (TDD)
Implementing secure authentication using OAuth, managed identities, and Azure security best practices
Writing unit and integration tests, conducting code reviews to maintain quality standards
Monitoring, troubleshooting, and performance optimization of Azure-based solutions
Strong ownership mindset with a drive for continuous improvement

Desirable experience:

Payment integration platforms
Scrum or Kanban methodologies
Automation tools such as GitHub Copilot
React or other single-page application frameworks
TypeScript, CSS3, HTML5, JavaScript, and ASP.NET MVC

Application Process

Please apply using your CV only
Think carefully about the skills, knowledge and experience in the advert and cover this in your CV
PDF format preferred and do not include any photographs or images

Equality, diversity and inclusion

We are committed to equality, diversity and inclusion. We want to represent the city we serve, which will help us become a more innovative and efficient organisation. Our goal is to make our recruitment as inclusive as possible. We are a disability confident employer who guarantee an interview to any disabled candidate who meets all of the essential criteria. We also use anonymising software that removes identifying information from CVs and cover letters to make the process fair.

Benefits

In return for your commitment and expertise, you will enjoy excellent benefits and scope to grow. Rewards vary according to the level of role but mostly include the below:

Final salary pension scheme
Free travel for you on the TfL network
Reimbursement of 75% of the cost of a standard class Ticket for National Rail travel from home
30 days annual leave plus public and bank holidays
TfL is committed to work-life balance, operating a hybrid working approach where business and role requirements allow
Private healthcare discounted scheme (optional)
Tax-efficient cycle-to-work programme
Retail, health, leisure and travel offers
Discounted Eurostar travel

We will make every effort to give you as much notice as possible, however some interviews/assessments could be organised at short notice.

Vetting Process

At Transport for London, safety, trust and fairness sit at the heart of how we recruit. Our Vetting Charter (https://tfl.gov.uk/corporate/careers/our-vetting-process) explains the checks we carry out before you join us, helping ensure we create a safe, inclusive and reliable network for everyone who depends on our services. We simply ask that the information you provide is honest and accurate so we can progress your application smoothly. If something doesn’t match or can’t be verified, we may not be able to move forward with your application, but we’ll always treat you with transparency, respect, and clear communication throughout.
