Java Backend Software Engineer

This role is offered on an Italian employment contract. Candidates must be based in Italy as we are unable to support remote working from outside the country due to local employment and tax legislation.

This role sits within the Vesper team at Deltatre — the platform responsible for delivering VOD and live events to users at global scale. You will work across Java services, event-driven processes, RESTful APIs, and the AWS infrastructure that underpins our streaming platform.

We are hiring at two levels. Both roles require someone who takes ownership, thinks carefully about system design, and is committed to engineering problems that genuinely matter at scale. The distinction lies in depth of experience, degree of independence, and scope of contribution.

Senior Java Backend Software Engineer
For engineers with deep production experience who are ready to influence how the platform evolves.

As a Senior Java Backend Software Engineer, you will take end-to-end ownership of complex features and system components. You will contribute actively to system and API design, participate in architecture discussions with well-formed opinions, and help raise engineering standards through code review and technical mentorship.

Your day-to-day will include:

Build, maintain, and optimise Java services running event-driven processes and RESTful APIs on AWS infrastructure

Own the design and implementation of robust, scalable solutions for VOD and live event delivery

Take an active role in system and API design discussions — bringing well-reasoned proposals and seeing them through to delivery

Write and maintain automated tests and contribute to defining test approaches across the team

Participate in code review, setting and maintaining engineering standards

Identify and address performance bottlenecks, reliability risks, and technical debt proactively

Mentor mid-level engineers through review, pairing, and day-to-day technical guidance

Mid-Level Java Backend Software Engineer
For engineers with solid foundations who are ready to take on meaningful ownership and deepen their craft.

As a Mid-Level Java Backend Software Engineer, you will take ownership of features and components within the Vesper platform, working with increasing independence on well-scoped problems. 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, maintain, and optimise Java services running event-driven processes and RESTful APIs on AWS infrastructure

Implement solutions for VOD and live event delivery, taking ownership of features from design through to production with appropriate guidance

Contribute to system and API design discussions — asking good questions, raising concerns, and sharing your perspective

Write automated tests and develop your ability to design meaningful test cases

Participate actively in code review — giving and receiving feedback constructively

Identify performance and reliability issues within your scope and raise them clearly

Work closely with QA and product within an agile delivery model

Requirements
What we're looking for at Senior level
