Java Software Engineer

2 X Software Engineers (Java / Data Platform)

Remote First (Must be UK based with full right to work with no sponsorship)

£75,000–£95,000

**Monthly meetups in London - fully expensed /optional. Access to offices should you prefer

I’m working with a global consumer platform processing millions of user events, building systems that turn raw behavioural data into real-time insights and recommendations.

This is not a typical backend role. It sits at the intersection of data, distributed systems and product, working on one of the most unique user datasets in its space.

They’re looking for a Senior Engineer to join a small, high-impact team.

The role

You’ll be working on systems that ingest, process and make sense of large-scale, messy datasets, helping to power insights, recommendations and user-facing features.

You’ll be:

• Building and evolving distributed systems that process high-volume user data
• Developing services that power APIs, real-time pipelines and core platform functionality
• Working closely with product and engineering to shape how data is structured and used
• Improving data quality, consistency and scalability across complex datasets
• Contributing to architecture and technical direction within a small team

Tech environment

• Java (core language)
• Python (supporting)
• Spark / Dataproc
• Distributed systems and data pipelines
• AWS / GCP

What they’re looking for

• Strong Java engineering background (5+ years)
• Experience building distributed systems, data pipelines or high-volume services
• Comfortable working with large, imperfect datasets
• Experience in product-led or scale-up environments
• Engineers who take ownership and enjoy solving complex problems

Nice to have

• Kafka, Hadoop, Cassandra, Redis or similar
• Experience with real-time or event-driven systems
• Exposure to recommendation systems, ML or data-driven products
• Cloud experience (AWS or GCP)

Why it’s interesting

• Millions of users – real impact at scale
• Complex data challenges – not just CRUD systems
• Small team, high ownership – no layers
• Strong product + data intersection
• Remote-first with optional London meetups

If you enjoy working on data-heavy systems, solving real-world scale problems and want to be in a team where engineering genuinely shapes the product, this is worth a conversation.
