[Hiring] Senior Software Engineer @Gentrack

Role Description

Factor is an API driven, AI powered retail data platform for global energy utilities.

We believe that great environmental outcomes come from smarter commercial models, and we earn our clients’ loyalty by helping them do good and do well.

• 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

Requirements

• 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
