This is a team-lead role within Deltatre's .NET backend engineering organisation, supporting the platforms that power OTT streaming, live broadcast, and digital products for major sports rights owners and media companies.

You will lead a cross-functional engineering team — combining technical authority over the work the team produces with direct accountability for how the team operates: delivery quality, performance, professional development, and the standards the team holds itself to. You will still write code where it matters and lead architectural decisions, but your central job is making the team effective at what it ships.

Unlike the Principal track at Deltatre, this is a people-leading role. You will have direct reports, run performance conversations, and be accountable for how the team's work integrates with the wider engineering organisation.

Responsibilities

• Lead a cross-functional engineering team building backend services for cloud-based media platforms — owning delivery, quality, and the team's technical direction
• Lead architectural decisions for the team's portfolio, ensuring scalability, performance, and long-term maintainability
• Set and enforce engineering standards within the team and align with the wider .NET engineering organisation
• Lead engineers through one-to-ones, performance conversations, and career development — building capability over time
• Collaborate closely with engineering peers, product leadership, and client teams to translate roadmap into delivery
• Oversee production incident response for the team's services, leading post-mortems and the improvements that follow
• Manage technical debt deliberately — when to take it on, when to pay it down
• Contribute hands-on to the most complex or highest-leverage work the team owns

You lead the work, and you lead the people doing the work. You are honest with your team about what is going well and what is not, and they are better engineers for having worked for you. You are credible technically because you still ship — but you spend your time deliberately, on the things only you can do.

Required

• Substantial production experience with .NET (6+), C#, ASP.NET Core
• Demonstrated experience leading a cross-functional engineering team, including direct line management
• Solid architectural judgement — making and defending design decisions on real systems
• Experience with distributed systems — microservices, event-driven design (RabbitMQ or equivalent)
• Production experience with at least one major cloud platform (Azure, AWS) and container orchestration (Docker, Kubernetes)
• Solid data persistence experience — MS SQL Server, MongoDB, Redis, EF Core or NHibernate
• Experience leading or contributing to engineering performance and career development conversations
• Comfortable as the technical face of the team in client and senior stakeholder conversations

Valued

• Background in media streaming systems — HLS, MPEG-DASH, DRM, video workflow orchestration
• AWS or Azure Media Services experience
• Experience setting up or improving CI/CD pipelines
• TDD discipline and a serious testing culture
• Experience supporting engineers from junior through senior progression

Who Thrives Here

This role asks you to operate in two directions at once. Outwards: you are the technical voice of the team to product, to engineering leadership, and sometimes to clients — you absorb ambiguity from above so your engineers can do their work. Inwards: you are responsible for the team being a good place to be an engineer, which means making honest assessments, having the conversations other people avoid, and protecting the team's time and focus.

People who thrive in this role tend to be technical enough that engineers trust their judgement, human enough that they do not reduce people to tickets, and disciplined enough to spend their time on what only they can do.

Process and what to expect

• Introductory conversation: this is a step for us to get to know each other better, and for us to answer all questions you might have around Deltatre.
• Take-Home Assessment: we have a coding challenge waiting for you, to grab a sense of what you'll be dealing with. This step is the entry point in our process, and mandatory to acccess to the followng steps.
• 1-hour Technical round of Interview: we will use your Assessment as a starting point for a discussion with Senior team members in the video team. You will do code review and discuss additional technical aspects in details. This conversation, combined with the output of the assessment will allow us to make a solid technical evaluation.
• 1-hour Competency Based Interview: we are going to ask you some situational questions around how you deal with real-life scenarios at work. Easier doing it, more than explaining it!

If any of these formats would be difficult for you, tell us — we adjust regularly and can usually accommodate.

Accessibility and accommodation questions are welcome at any stage, including before you apply. Tell us what would work for you.
