This role sits within the Vesper team at Deltatre — the platform powering live and on-demand streaming experiences for some of the world's most recognised media brands. You will work across web, React Native mobile, and connected TV (10-foot) applications, contributing to the component systems, performance standards, and delivery pipelines that underpin our clients' products.
We are hiring at two levels. Both roles are hands-on engineering positions for people who care about quality, take ownership of their work, and are comfortable in a cross-functional environment. The distinction lies in depth of experience, scope of contribution, and degree of independence expected.
Senior Front-End Software Engineer
For engineers who are ready to lead solutions and raise the bar for those around them.
As a Senior Front-End Engineer, you will take end-to-end ownership of features and solutions across our platform. Beyond your own delivery, you will contribute actively to how the team works — mentoring less experienced developers, shaping technical decisions at the solution and feature level, and helping establish standards that others build on.
Your day-to-day will include:
-
Design, build, and maintain high-quality front-end experiences across web, React Native mobile, and connected TV platforms (tvOS, Android TV / Fire TV, Samsung Tizen, LG webOS)
-
Take the lead on solution and feature design — bringing well-reasoned technical proposals and seeing them through to delivery
-
Mentor mid-level and junior developers through code review, pairing, and day-to-day guidance — helping build capability across the team
-
Contribute to and evolve our shared component library and design system, with a focus on consistency, accessibility, and long-term maintainability
-
Set a high bar for front-end performance — profiling, measuring, and improving rendering, load times, and analytics instrumentation
-
Collaborate with back-end engineers, QA, and product to define robust, scalable solutions
-
Contribute to CI/CD pipelines and front-end tooling, improving build reliability and developer experience
-
Stay current with the front-end ecosystem and bring emerging patterns and practice into the team
Mid-Level Front-End Software Engineer
For engineers with solid foundations who are ready to take on meaningful ownership and grow their craft.
As a Mid-Level Front-End Engineer, you will take ownership of features and components within the Vesper platform, working with increasing independence across our target environments. You will collaborate closely with senior engineers and contribute to a team culture where quality and continuous improvement matter.
Your day-to-day will include:
-
Build and maintain high-quality front-end experiences across web, React Native mobile, and connected TV platforms
-
Contribute to our shared component library and design system — writing reusable, accessible, maintainable code
-
Apply front-end performance principles — understanding how your code affects rendering, load times, and instrumentation
-
Participate in technical design discussions, asking good questions and contributing your perspective
-
Collaborate with back-end engineers, QA, and product teams to deliver robust solutions
-
Work within CI/CD pipelines and front-end tooling as a self-sufficient contributor
-
Develop your knowledge of the front-end ecosystem and apply it to your work
