Job description

Overview

At Fuse, we're building a fully integrated energy company, from developing solar, wind, and hydrogen to power trading & distributed energy installations. We sell directly to energy consumers, cutting out the middleman to reduce costs and pass on savings to customers.

But we’re not stopping there. We’re also building the Energy Network: a decentralized network of smart devices where users get rewarded in Energy Dollars for electrifying their homes, shifting usage to off-peak hours, and helping balance the grid. The energy network helps the grid achieve energy stability, a crucial requirement for growth of AI data centers and energy intensive industries.

We’ve raised $90M from top-tier investors including Multicoin, Balderton, Lakestar, Accel, Creandum, Lowercarbon, Ribbit, Box Group, and strategic angels like Nico Rosberg, co-founder of Solana, and GPs behind Meta, Revolut, Spotify, Uber, and more.

• Establish engineering best practices for observability, CI/CD, testing, and scalability
• Partner closely with product and backend teams to support rapid development cycles

Qualifications

• Proven track record as a senior software engineer or tech lead, ideally with platform/backend focus
• 5+ years experience in software engineering, with 2+ years in a leadership role
• Experience building and operating production-grade systems at scale
• Strong understanding of system design, distributed computing, and cloud infrastructure
• Clear and proactive communication, with the ability to align cross-functional teams
• Hands-on approach to solving problems and making strategic decisions

Bonus

• Experience with Infrastructure as Code (e.g., AWS CDK, Terraform)
• Experience with event-driven architecture, messaging queues, or stream processing
• Familiarity with building internal platforms or developer tooling

Benefits
