your profile
doesn't fit every requirement but you believe you can bring a unique perspective, we strongly encourage you to apply. We're well-funded and backed by top investors, providing the resources you wish you had when building your own business. We don't care about traditional roles or titles—just that you're smart, proactive, and bring the same founder-level ownership and drive to help us build something massive. JOB SUMMARY As a Business Development Manager, you will play a central role in accelerating HyLight's commercial growth. Working closely with our CBO, you will own the full commercial pipeline for a defined set of accounts and territories — from prospecting through to closing — engaging directly with senior stakeholders at Europe's largest infrastructure operators. This is not a support role. You'll be given real ownership over revenue targets, account strategy, and go-to-market decisions, while helping build the commercial foundations of a fast-growing climate tech company from the ground up. THE MISSION Reporting to the CBO, you will:
* Own and grow a portfolio of target accounts across our key industries (gas, power, and other infrastructure operators).
* Build, qualify, and prioritize pipeline through outbound prospecting, market research, and commercial intelligence.
* Lead the full sales cycle: outreach, discovery, technical/commercial qualification, proposal, negotiation, and close.
* Manage and deepen relationships with key infrastructure operators, from first contact through to contract renewal.
* Define and execute account and territory strategy, including identifying new markets and expansion opportunities.
* Analyze customer needs, market trends, and competitive dynamics to sharpen HyLight's commercial strategy.
* Partner closely with technical and product teams to translate customer challenges into HyLight's value proposition and roadmap input.
* Build and improve scalable commercial processes (CRM hygiene, playbooks, forecasting) as the team grows.
* Represent HyLight at industry events, conferences, and client sites. PROFILE SOUGHT EXPERIENCE
* 4+ years of B2B business development, sales, or account management experience, ideally in infrastructure, energy, industrial services, deep tech, or a related B2B technical sales environment.
* Track record of owning and closing complex, multi-stakeholder deals with enterprise or utility-scale customers.
* Experience building outbound pipeline and managing a sales cycle end-to-end, not just account management. TECHNICAL SKILLS
* Strong analytical and research skills; comfortable building business cases and ROI arguments for technical buyers.
* Excellent written and verbal communication, including with senior/executive stakeholders.
* Fluent with CRM tools (HubSpot, Salesforce, or similar) and comfortable owning pipeline reporting and forecasting.
* Proficient with Excel/Google Sheets and presentation tools. SOFT SKILLS
* Founder-level ownership and autonomy; comfortable operating with significant independence.
* Proactive, resourceful, and comfortable taking initiative in ambiguous, fast-changing environments.
* Comfortable taking calculated risks and making fast decisions with incomplete information.
* Rigorous and organized in delivering high-quality work under deadline pressure.
* Curious, eager to learn technical subject matter, and passionate about building and experimenting.
* Strong team player, comfortable working in a fast-paced, multidisciplinary team. Languages: French and English required. BONUS QUALITIES
* Experience selling into utilities, energy, or infrastructure operators specifically.
* Experience selling technical/hardware-enabled or data/analytics products to industrial buyers.
* Prior startup or scale-up commercial experience.
* Interest or background in climate tech, energy, infrastructure, or deep tech.
