Front-End Lead Engineer
This role is offered on a UK employment contract. Candidates must be based in the UK as we are unable to support remote working from outside the country due to local employment and tax legislation.
This role sits within Deltatre's OTT delivery organisation, where front-end engineering teams build the applications millions of fans use to watch live and on-demand sport. The team combines hands-on engineering with the delivery discipline needed to ship reliably across major international projects.
As Front-End Lead Engineer, you will drive the development of high-quality, scalable front-end solutions while staying hands-on with the code. You'll shape front-end architecture, set engineering standards across delivery teams, guide and mentor engineers, and act as the main technical point of contact between your team and stakeholders.
Responsibilities
Technical Excellence
- Oversee all front-end engineering aspects of assigned projects, ensuring robust, scalable, secure, high-performing, and accessible solutions
- Plan, schedule, coordinate, and monitor front-end development activities, driving task prioritisation and providing technical assessments and estimations
- Review and validate the technical approach and code quality for all team deliverables, ensuring compliance with best practices, coding standards, and performance benchmarks
- Identify and resolve technical issues and blockers, raising concerns with proposed architecture and escalating when necessary
- Drive the adoption of automation, efficient tooling, and modern front-end technologies and methodologies
- Establish efficient front-end workflows and processes, and maintain supporting documentation, including architectural principles
Leadership and Team Growth
- Mentor, coach, and support the professional growth and onboarding of engineering team members
- Track and support performance feedback within the team
- Contribute to the recruitment and integration of new front-end team members

Who Thrives Here
This role sits between hands-on engineering and technical leadership - you're reviewing a pull request one moment and explaining an architectural trade-off to a client the next. It suits someone who wants to stay close to the code while also shaping how a team works.
People who do well here are comfortable making and owning architectural decisions, give feedback that actually helps engineers grow rather than just flagging problems, and can translate a technical constraint into terms a non-technical stakeholder can act on.
Process and what to expect
- Introductory conversation: a step for us to get to know each other better, and for us to answer all questions you might have around Deltatre.
- 1-hour Technical round of Interview: we will deep dive on your experience and collect examples of the responsibilities you've been dealing with in your past experience. A chance to deep dive on the role and for you to ask questions.
- 1-hour Competency Based Interview: we will ask you 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. Tell us what would work for you.
