About Nyxium: Nyxium is a decision intelligence platform for critical infrastructures. We help data centre and renewable energy developers, nuclear and storage investors, and the public bodies that govern them identify the right locations, surface hidden risks, and protect capital before major investments are made. We are a London-based deep-tech company backed by top-tier investors and founded by a team with backgrounds in nuclear science, environmental science, and software engineering. We are now at the transition from founder-led commercial activity to a scalable go-to-market motion, and this hire is the most important commercial decision we will make in 2026.
The Role: You will be Nyxium's first commercial hire and the architect of everything that follows. You will own the full pipeline end to end: sourcing conversations, running live product demos, managing LOI and contract processes, setting customers up for success in their first 90 days, and building the playbook that trains everyone who comes after you. This is not a quota carrier role in a mature company. There is no marketing function generating inbound, no SDR booking meetings, and no sales team beneath you yet. You are the commercial function, building it as you run it, using a defined founding customer playbook as the starting point. The ceiling on this role is the ceiling on Nyxium's growth. The person in this position in three years will be Chief Revenue Officer of a company with 100 or more enterprise customers and a commercial team they have personally trained and hired.
The equity and commission structure reflect that potential. This is a highly specific hire. Every criterion below is a genuine hard filter, not an aspirational preference. We will assess every candidate against all of them before progressing to first conversation.
Education: Degree-level qualification or equivalent professional achievement required. Relevant backgrounds may include:
- Geography
- Infrastructure Development
- Business or Commercial Strategy
Equivalent commercial experience within infrastructure sectors will also be considered.
Experience:
- 10+ years of experience within data centre development, renewable energy, energy infrastructure, nuclear, or related sectors
- Prior experience operating at VP, Director, Head of Commercial, or equivalent senior level
- Proven experience closing enterprise deals valued between £50K–£500K+ ACV
- Experience managing multi-stakeholder enterprise sales cycles involving procurement and legal negotiation
- Existing network of senior infrastructure or energy-sector decision-makers
- Demonstrated ability to operate successfully in high-autonomy or early-stage environments
- 10+ years in data centre development, renewable energy development, or energy infrastructure — inside the sector, not advising from a distance
- VP-level seniority or equivalent with full commercial ownership in at least one prior role
- Proven track record closing £50K–£500K ACV enterprise deals with 3–6 month close cycles, procurement review, and legal negotiation
- Personal network of 10+ VP-level infrastructure development decision-makers who would take your call this week — not conference contacts, but people you have worked alongside or sold to directly
- Experience managing multi-stakeholder sales: champion identification, procurement navigation, success criteria definition
- Demonstrable ability to sell an early-stage product honestly: leading with what it does well today, being transparent about the roadmap, and converting that transparency into trust
- Degree-level qualification or equivalent professional achievement
- 15+ years with a portfolio of reference customers who will speak publicly
- Prior commercial experience at a data intelligence, site selection, or infrastructure advisory firm
- Has personally led a site selection process for a data centre or energy project from brief to final decision
- Experience building a commercial playbook or structured sales process from scratch
- Existing relationships with mid-sized data centre or renewable energy developers in the UK, Europe, or the US
- Has hired and onboarded a junior commercial team member
Personal Qualities: We are looking for someone who is:
- Commercially strategic and execution-focused
- Comfortable building systems from zero
- Credible in front of senior infrastructure stakeholders
- Highly organised and process-oriented
- Transparent, consultative, and trust-driven in sales approach
- Motivated by long-term equity upside and company growth.
What this is not: This is not the right role if you need a marketing team generating inbound before you can operate. It is not the right role if you have only sold to technology companies or financial services. It is not the right role if your primary goal is a high base salary. It is not the right role if you describe your sales style as relationship-based without being able to name the specific relationships. It is not the right role if you are not ready to be the first and only commercial person at an early-stage company.
Compensation and Benefits: Direct equity in Nyxium Ltd with a 1-year cliff. Uncapped commission paid on closed ARR, settled yearly.
