About the Role

At Factor, we’re building the commercialisation layer for the new energy economy. Our engineers shape the foundations of a platform designed to transform how energy is priced, forecast, and delivered globally. You will play a pivotal role in developing the core of our system: scalable data pipelines, pricing engines, and APIs that support real-time decision making for energy retailers and their customers. You’ll work in a highly capable senior team, where ownership, curiosity, and engineering excellence are expected — and where AI tools are used daily to multiply impact and velocity.

Responsibilities

  • Build and ship backend features and services with a focus on elegance, scalability, performance, and resilience.
  • Design and evolve Factor’s core data and application architecture (Typescript rust, AWS, etc).
  • Solve complex, end-to-end problems across the stack, from data ingestion and transformation, complex algorithms, through to APIs and partner integrations.
  • Contribute to engineering standards, peer reviews, and design discussions that raise the technical bar.
  • Use AI and automation to accelerate development cycles, testing, and deployment.
  • Help shape a culture of technical excellence, collaboration, and high ownership.

Requirements

  • Proficiency in Node.js, Python, PostgreSQL, and modern cloud architecture (AWS, serverless).
  • Track record of designing and maintaining clean, maintainable systems that handle complex data and business logic.
  • Experience in the energy sector (or other data-heavy, mission-critical industries) is highly valued.
  • Comfortable working autonomously in a fast-moving startup environment; proactive in surfacing problems and proposing solutions.
  • Thrives on responsibility and ownership, with a low-ego, high-collaboration style.
  • Excited by the opportunity to apply your skills to one of the world’s biggest challenges: the energy transition.
