Posted Updated

Description

The role


We're looking for a strong, hands-on Tech Lead to help build a Real Time commodity intelligence platform from the ground up. This is a generalist data/platform engineering role. You'll design the architecture and write the production code behind it.


The work cuts across streaming, graph, time-series and large-scale data. If you like hard problems and want to own the technical direction of something new, this is it.


What you'll be doing



  • Designing and building Real Time streaming pipelines on Kafka

  • Architecting a lakehouse platform using Apache Iceberg

  • Building high-performance analytics over large-scale and temporal (time-series) data

  • Developing knowledge graphs, semantic models and ontologies to give the data structure and meaning

  • Bringing AI and agent-based reasoning into the platform

  • Designing distributed systems that scale, and writing production-grade code to deliver them

  • Setting technical direction and standards as the platform grows


What you'll bring



  • Strong hands-on experience as a data or platform engineer, at Tech Lead level or close to it

  • Deep Kafka and Real Time streaming experience

  • Experience with Iceberg or other lakehouse technologies

  • A track record of designing and building distributed systems

  • Experience with time-series/temporal data and high-performance analytics

  • Exposure to knowledge graphs, semantics or ontologies

  • Interest in AI/agent reasoning and how to apply it to real data problems

  • Comfortable switching between architecture and code, and keen to work across the whole stack


Nice to have



  • Commodities, energy or trading background

  • Experience building a platform from scratch
