Job description

Business Development Manager (m/f/d) Quantum & Photonics

Nationwide

Do you want to do more than just explain technologies – do you want to create markets for them? Then join us in shaping the future of intelligent sensor technology, photonics, and quantum technology – from the initial customer impulse to scalable applications.

duotec combines innovative quantum technologies with electronics development, manufacturing, and customized sensor solutions. The portfolio ranges from spectrometers to quantum technology solutions featuring single-photon counting and integrated timetaggers. Quantum Technologies develops high-precision quantum sensor systems with a focus on magnetic field sensing. Our aspiration is to transform scientifically demanding technologies into robust, relevant, and commercially successful applications.

To strengthen our alliance, we are looking for an entrepreneurial Business Development Manager (m/f/d) who will act as a commercial bridge between both worlds and turn deep-tech innovations into real customer applications.

Your Mission

You are the commercial impulse generator at the intersection of technology, market, and customer. Together with the teams at duotec and Quantum Technologies , you develop new business fields, identify the right applications, and turn deep-tech innovations into concrete customer projects, partnerships, and growth. You won't be working within a rigid sales structure: You act entrepreneurially, think in opportunities rather than boundaries, and bring structure to markets that are just emerging.

• Market & Potential Analysis: Developing business potential and identifying relevant applications, target customers, and markets around intelligent magnetic field and current sensors, photonic precision measurement, quantum-based sensor solutions, as well as specifically NV-center-based quantum sensorics, single-photon detection, and timetagging.
• Strategic Solution Design: Leading sophisticated technical discussions beyond pure product sales to identify engineering challenges and application potentials, co-creating compelling solutions together with customers.
• Strategy & Value Propositions: Translating technological complexity into clear value propositions, relevant business cases, and resilient go-to-market strategies.
• Partnerships & Networks: Building strategic relationships with OEMs, integrators, multipliers, research and technology partners, as well as developing new partnership, sales, and business models for markets with long innovation cycles and high technological demands.
• Project & Process Management: Guiding opportunities from the initial hypothesis through proof-of-concepts and customer projects to hand-over into a scalable sales process.
• Interface Work & Representation: Working closely with the R&D teams of both companies, including independently shaping product and market feedback so it feeds into early technology and product decisions; representing the company during customer meetings, trade fairs, conferences, and within strategic networks.

Your Profil

You combine technical understanding with true commercial instinct. You don't need to build every physical detail yourself – but you enjoy understanding complex technologies and bringing their customer benefit precisely to the point.

• Education / Experience: Successfully completed degree or comparable practical experience in physics, electrical engineering, photonics, quantum technology, or sensor technology. Ideally with initial touchpoints in magnetic field or current sensors, optical measurement methods, semiconductors, or industrial measurement technology.
• Track Record: Several years of experience in technical B2B sales, business development, technical sales, product management, or strategy consulting in the deep-tech sector – particularly with a proven track record in market building, customer relationship management, strategic partnerships, or launching new product/application fields.
• Tech Affinity: Enthusiasm for complex, highly technical products and the ability to derive clear, credible customer value from them, combined with a confident demeanor when interacting with technical experts, heads of R&D, buyers, management, and research partners.
• Mindset & Language: Entrepreneurial mindset, initiative, and a pragmatic hands-on attitude, along with very good German and English language skills and readiness to travel.

Our Offer & Your Prospects

• Two Locations, Two Worlds, One Mission: The perfect combination of duotec’s electronics and manufacturing expertise in Halver and Quantum Technologies’ high-precision quantum sensorics in Leipzig.
• Real Creative Freedom: Flat hierarchies, short decision-making paths, and the freedom to turn your own ideas directly into market-ready products and new business areas.
• Flexibility & Mobility: Trust-based working hours and mobile working remote across Germany. Since close collaboration with on-site teams in Halver and Leipzig as well as with customers is essential, a corresponding presence and readiness to travel is required. A modern, fully equipped company car (also available for private use) is provided for these meetings, trade shows, and site visits.
• Attractive Package: A competitive, performance-related compensation model, holiday and Christmas bonuses, 30 days of vacation, €95/month company pension scheme (bAV) from day 1, e-bike leasing, comprehensive supplementary insurance, and attractive corporate benefits.

Sounds Like You?

We look forward to meeting you if you are always curious, act entrepreneurially, and want to create real market impact from technological depth.

We look forward to getting to know you!
