Fractional Head of Sales, Tarian Labs
FRACTIONAL SALES JOB · COMPUTER AND NETWORK SECURITY SECTOR · UNITED KINGDOM

Tarian Labs, a 2–10 person UK cybersecurity consultancy, is seeking a fractional Business Development Manager to own hands-on sales prospecting and pipeline build. Explicitly 2–4 days/month at £300–£400/day plus 5–10% commission on new business closed. Early-stage, remote-first, founders handle technical delivery.
Fractional Head of Sales — the balanced verdict
- Explicit fractional engagement with clear day rate, commission structure and ramp expectations
- Hands-on, outcome-focused brief — personal pipeline generation and deal close, not strategy docs
- Strong technical buyer alignment (CISOs, CTOs, procurement) and niche cybersecurity domain (penetration testing, CREST, managed security)
- Founder-led technical scoping removes sales engineer burden; pure BD/AE focus
- 2–4 days/month is genuinely light; not suitable for someone seeking 2–3 days/week baseline income
- Commission contingent on client payment, not signature; cash-flow risk if client payment delays
- Expects UK market relationships and direct cybersecurity sales track record; domain-specific bar is high
Fractional Head of Sales — the posting in full
Tarian Labs is looking for an experienced fractional Business Development Manager / Sales to help grow our penetration testing and cybersecurity consultancy.
We are an early-stage UK cybersecurity company led by experienced penetration testers. We have strong technical capability and existing client delivery experience; we are now looking for someone who can take ownership of building a consistent sales pipeline and developing new client relationships.
This is a hands-on sales role. We are not looking for someone to simply produce a sales strategy or marketing plan. We need someone who can identify opportunities, start conversations, qualify requirements and help turn those conversations into business.
The role will include:
- Identifying organisations that procure penetration testing and related cybersecurity services
- Building and managing a qualified sales pipeline
- Outbound prospecting through LinkedIn, email, telephone and existing networks
- Developing relationships with CISOs, security managers, CTOs, procurement teams and other relevant buyers
- Running initial commercial and qualification conversations
- Maintaining CRM records and providing clear pipeline reporting
- Progressing opportunities through the sales process
- Supporting proposals, pricing and commercial negotiations
- Developing referral, partner and channel opportunities
- Working directly with the founders, who will handle technical discovery, scoping and specialist discussions
We are specifically looking for someone with demonstrable experience selling cybersecurity services, ideally including one or more of the following:
- Penetration testing
- Cybersecurity consultancy
- CREST or CHECK-related services
- Managed security services
- Security assessments, assurance or offensive security services
Experience selling directly to UK organisations and existing relationships within the cybersecurity market would be particularly valuable.
You should be able to demonstrate where you have personally generated opportunities, opened new accounts, developed client relationships and contributed to closing cybersecurity services business.
This is a fractional contractor engagement rather than a permanent full-time position.
We expect to begin with:
- An initial 90-day engagement
- Approximately 2–4 days per month initially
- £300–£400 per day depending on experience
- Performance-related commission of approximately 5–10% on new business originated, depending on deal size
Commission would apply to genuinely new business generated by you and would be paid once Tarian Labs has been paid by the client.
The role is primarily remote and UK-focused, although occasional customer or partner meetings may be required.
If you are interested, please send us a brief introduction outlining your relevant cybersecurity sales experience, the types of services you have sold, typical deal sizes, the customers you sold to, and examples of business you personally helped generate.
