Senior Software Engineer - Market Operations

About Us

Fractal Power is a vertically integrated power company built for the modern grid. We own and operate across the entire stack, combining utility-scale energy storage infrastructure with algorithmic trading and dispatch to deliver power precisely where and when it's needed most.

We are backed by the world's leading infrastructure and deeptech investors, including Riot , Definition , and Worldbuild .

Why Join Us?

Demand for power is growing at the fastest rate since WWII yet supply is stranded behind worsening transmission and interconnection bottlenecks. The new economy requires a new model of power delivery, one that's vertically integrated, algorithmically operated, and co-located with demand.

We solve the last-mile infrastructure problem by vertically integrating across the entire value chain of American power - from greenfield development, to algorithmic optimization, dispatch, and power trading across a fleet of distributed resources - allowing us to deliver power where and when it's needed most on the grid. We have the ambition, the team, and the zeal to create the next great power company and we are looking for fanatical people to join us.

About the role

You'll own the market operations platform end to end - from the UI down to the infrastructure underneath it. That means real-time optimization across tens of batteries, trading strategies for DART, PTP, and CRR/FTR, the interface traders and quants use every day, our connections to the ISOs we trade in, and the settlement and risk management systems that sit underneath all of it. There's no platform team to hand the unglamorous half to, and no one else to point at when something breaks.

We are targeting live operation in the next 2-3 months. You'll need to execute from day one. That means you'll have a real say in the architecture, the stack, and the sequencing - not just the decisions handed down to you, but the ones you'll make yourself as the system takes shape.

You'll work directly with traders and quants: sitting with them to understand what's actually slowing them down, and building the roadmap together as part of a small engineering team, with no PM layer in between.

It's a lean team with a lot of responsibility per person. No politics, no layers of sign-off - just building and shipping, with the people who'll actually use what you build.

What you'll build

• Market operations platform: Battery optimizer and DART, PTP, and CRR/FTR trading strategies, from signal to live position - energy and ancillary services, day-ahead and real-time - with battery state of charge and overall market position kept consistent throughout. It's also the interface the trading team lives in every day: positions, P&L, risk controls, bid construction, submission and approvals, and the audit trail underneath every action in the system.

• Market interfaces and telemetry. Integration with our scheduling entities and the ISOs we trade in - submission, notifications, settlement data, and each market's own retry semantics and submission-deadline obligations - alongside reliable ingestion of market data, asset telemetry, and state of charge, with monitoring that catches a stale feed before a trader does.

• Settlement and liquidity management. Statement ingestion and reconciliation, invoice validation, disputes, collateral tracking, and the reporting finance and risk depend on.

What we're looking for

• 8+ years building production systems, including something you took from zero to scale

• End-to-end ownership. Comfortable owning the product from trading platform UI down through the infrastructure that supports it

• Strong product ownership. You're building for a handful of demanding users with no PM in between - you should be able to watch a trader work, spot what's actually costing them, and design something they'll use without being asked twice

• 0-to-1 experience with an eye on longevity - you can stand up a system fast without building something that collapses under its own weight

• Tight collaboration with traders and quants - gathering requirements directly from the people using what you build, and turning them around fast

• Directness, and appetite for a domain you probably don't know yet. Understanding of energy markets is a plus, not a requirement - but you'll need to ramp up quickly

• An appetite for intensity. This job moves fast and doesn't let up - you should genuinely enjoy that pace, not just tolerate it
