Senior Backend Engineer - Data

Description:

Our customer base has grown fast, and our platform has to grow with it. We're looking for a senior backend engineer with a strong data-engineering background to own the pipelines and services that process data at scale across our platform. You'll take services from idea to production on your own: design, build, ship and run them, and you're not afraid to open old code and make it better.

IONIX External Exposure Management protects enterprises' external attack surface from cyber risks and increases security team efficiency by providing tools that shorten the time to discover and prioritize exposures. IONIX discovers every internet-facing asset, assesses dependencies and connections, and validates exploitable risks so teams can remediate the exposures that matter. Global leaders including BlackRock, Infosys, Sompo, The Telegraph and E.ON depend on IONIX to manage their complex and dynamic attack surface.

• Design, build, and run ingestion pipelines that collect internet-scale data from diverse public and third-party sources, handling rate limits, retries, and backfills.
• Own data modelling: schemas, partitioning, and storage layout that hold up as volume grows.
• Clean, normalise and deduplicate data from many noisy sources into consistent, trustworthy entities.
• Make data reliable: quality checks, freshness monitoring, fail-loud ingestion, backfills and recovery.
• Take features end to end, from the data to the customer: expose APIs, wire the UI when needed, and change code owned by other teams.
• Make data ready for analysis: build the ingestion and data-lake foundations our data analysts work on.
• Work with analysts to automate data verification and cleaning, and replace manual processes with automated ones.
• Solve scale and performance problems across pipelines and services.
• Improve and modernise existing code, not only write new code.
• Lead technical initiatives and raise the bar for the team.
• Own your work in production. Take part in on-call, take initiative to cut alert noise and fix root causes, not only symptoms.
• Use AI tools and agents as a core part of how you build.
