Java ETL Data Engineer

Our SynaptiQ platform collects near-real-time data from more than 20 million devices across thousands of utility-scale solar and wind sites worldwide. Everything the platform does — the analytics, the alarming, the reporting our clients run their portfolios on — depends on that data arriving complete, on time and correctly normalised. To keep that foundation solid as the portfolio grows, we are looking for a Senior Java ETL Data Engineer to own the technical direction of the engine that makes it happen.

You will join our Product Engineering organisation, working in a small cross-functional team of 2–3 engineers and reporting to an Engineering Manager. You will work closely with Product Management to define both what gets built and how it is implemented, and with Operations when things break. The working language is English. Day to day you will be in high-performance Java, S3-compatible object storage (S3, ABS, GCS), streaming infrastructure, and Linux.

This is a senior individual contributor role. You will own the ETL engine — not a slice of it - and day-to-day:

• You design, develop and operate the Java ETL engine that processes near-real-time data from millions of renewable energy assets. Ownership here runs from conception through to production operation: you build it, you run it, you fix it.
• You architect and integrate the engine with S3-compatible object storage and streaming infrastructure. Deciding how and when we adopt a given storage or streaming technology is your call to make and justify.
• You balance the technical trade-offs between real-time and batch processing, and make those calls on evidence rather than preference.
• You take the lead on quality and reliability through code review, testing and SRE practice — including incident response and postmortem analysis when something goes wrong at 2am on a Sunday.
• You decompose pipeline problems into actionable milestones and plans, so the team knows what "done" looks like before work starts.
• You maintain the architecture decisions, runbooks and API documentation that let the rest of us operate what you build.

Requirements

We are looking for someone who takes an idea all the way to production and stays with it afterwards. Someone technically rigorous, who writes high-performance concurrent Java and genuinely cares how systems behave under load at three in the morning. And someone pragmatic — who knows when to ship and when to slow down and do it properly. To qualify as our ideal candidate:

• You have 7+ years of software engineering experience, including at least 3 years writing and operating high-performance Java in production.
