Apply for the Commercial Manager
Location: London
Job Description:

Location: London, UK (Hybrid, 3 days/week in office)

Compensation: Competitive salary, bonus, benefits and stock options

Other: International travel to customers and industry events (Europe, Asia, North America)

About us

Flatpeak is the infra layer between energy devices and the grid. Every battery, EV charger and heat pump sold needs to know what electricity costs, minute by minute, and the grid needs to know what those devices can do: when they can charge, when they can hold back, when they can give power back. We provide both halves of that exchange as one platform, to some of the largest manufacturers in the world, across dozens of countries, so that their devices run on the cheapest, cleanest electricity and earn money for the flexibility they provide.

The Role

This is an early commercial hire with a wide brief. You will own every OEM outside our battery and EV segments: HEMS, EV charging and heating/cooling today, and whichever categories come next. You will win them, take them live and grow them. The sale is a design-win: discovery and engineering with the customer’s product team, integration, and then years of their devices running on your work. Right now one person does both halves because it’s key to keep the win and the integration closely coupled.

You will report to the co-founder who leads revenue and work closely with Business Development, Sales Operations, Data and Product.

We are preparing for our next funding round. When it closes, the revenue team grows around you: the book you have built splits into new-business and account roles by device cluster, with everything EV-related (chargers, charge point management, fleets) on one side and everything heating and cooling related (heat pumps, air conditioning, hot water) on the other, and you choose which cluster and which side you want to run with.

KPOs

New Business

  • Own the pipeline for HEMS/EMS, CPMS/EVSE and HVAC from qualification to signed agreement
  • Run discovery-led sales conversations that establish the customer’s use case, integration path and commercial model before any proposal is made
  • Bring at least one new OEM integration into scope each quarter and at least one customer each month
  • Represent Flatpeak at industry events and build relationships across the ecosystems we sell into
  • Maintain an accurate pipeline and forecast in the CRM

Customer Growth and Retention

  • Own tariff-data account management across your book and across our battery OEM customers, including integration progress, incidents, renewals and commercial expansion
  • Take every customer you sign from contract to live integration, working with Sales Engineering and Product to remove blockers
  • Track activation and usage so that every integration delivers value to the customer’s customers and end-users, not only to their product roadmap
  • Identify and close expansion into new markets, product lines and, in time, VPP and hardware propositions
  • Collect the inputs the business needs from customers: volume figures, reference and logo permissions, product feedback and incident reviews

Playbook and Process

  • Co-own the sales playbook: discovery questions, meeting structure, proposals and collateral
  • Document what works so that the process can be handed to a RevOps lead after the funding round
  • Feed structured customer and market insight back to Product, Business Development and the Data team
  • Work with Sales Operations to make reporting, follow-ups and CRM hygiene run without founder involvement

Our process:

  • Video call with Head of Sales
  • In-person interview in our London office
  • Annual Salary Review

We work from our Central London office (EC2) at least three days a week to keep collaboration, communication, and productivity strong. If the above is a fit, we’d love to hear from you!
