Sales Director

Fellten designs, engineers and manufactures modular battery energy storage systems (BESS) and electrification solutions from its Bristol base.

Our product range spans the Charge Qube family of containerised BESS and rapid EV-charging units (160kWh–1MWh), Universal Battery Packs for a wide range of applications. We hold ISO 9001, 14001 and 45001 certification and are scaling quickly as demand grows for flexible, rapid-deployment energy storage across EV charging, marine, and off-grid/hybrid power markets.
Commercially, Fellten is at start-up pace: we have a strong product and engineering base and are now building out the sales and marketing function from the ground up to match it.

The Opportunity
We're looking for an experienced Sales Director with an established network across energy storage, EV infrastructure, marine, or adjacent power/renewables markets to lead the charge in winning new customers — and to build the sales infrastructure (process, tools, and marketing assets) a fast-growing manufacturer needs to scale. This is a rare opportunity to shape Fellten's entire commercial strategy and build the sales function in your own image, with genuine equity upside as the company grows.

Key Responsibilities
•    Own new business development — use your existing relationships and network to generate and close sales opportunities across Fellten's BESS, EV charging, and marine product ranges.
•    Build and execute a commercial/sales strategy aligned with Fellten's growth targets, target markets, and product roadmap.
•    Design and implement a repeatable sales process: pipeline management, CRM, qualification criteria, forecasting, and reporting.
•    Develop sales and marketing assets — pitch decks, case studies, spec sheets, proposal templates, ROI/TCO models — working closely with product, engineering, and marketing.
•    Represent Fellten at industry events, trade shows, and conferences to build brand presence and generate leads.
•    Build key relationships with strategic accounts, channel partners, distributors, and EPCs across target verticals.
•    Work closely with the General Manager and leadership team, feeding customer and market insight into product strategy and pricing.
•    Recruit, mentor, and lead a small sales team as the function scales.
•    Own sales forecasting and revenue reporting to the leadership team and board.

What we're looking for

•    A proven track record as a Sales Director, Head of Sales, or senior business development leader in BESS, energy storage, EV charging infrastructure, renewables, or related capital equipment / cleantech sectors.
•    An established network of relevant contacts — buyers, developers, EPCs, fleet operators, marine operators, or channel partners.
•    Experience selling complex technical or capital products with long sales cycles, ideally B2B.
•    A builder's mindset — comfortable creating sales processes, tools, and collateral from scratch in a start-up or scale-up environment, not just operating within an established one.
•    Strong commercial acumen, comfortable owning pricing, forecasting, and margin discussions.
•    Excellent stakeholder management skills — credible with technical engineers through to C-suite buyers.
•    Willingness to travel across the UK/Europe and to be present at Fellten's Bristol base on a regular basis.
•    A genuine interest in electrification, decarbonisation, and the energy transition.

What we offer
•    A Very Competitive Base salary, depending on experience.
•    A significant Performance bonus opportunity, related to new revenue generated
•    Company car or car allowance.
•    Other leading benefits within a growing business
•    The chance to build and shape a very young commercial function , with real influence over strategy and product direction.
•    Hybrid working, based from Fellten's Bristol HQ / Home (To be agreed), with national travel to customers
