Description

We're building something extraordinary - and we want extraordinary people. As our Sole Counsel, you'll build 5D's legal function from scratch - the contractual infrastructure, compliance posture, and risk framework that supports every major commercial and operational decision between now and Series B.

Commercial (50%)

  • Own the full lifecycle of customer contracts - NDAs, MSAs, order forms, DPAs, and amendments - negotiating directly with procurement and legal counterparts at enterprise customers
  • Draft and negotiate vendor, partner, and employment agreements
  • Maintain and continuously improve our contract templates and negotiation playbooks
  • Manage a contract tracker; own the pipeline of open legal matters and keep deals moving
  • Brief and manage external counsel on matters beyond your scope

Compliance (30%)

  • Work closely with our vCISO to maintain ISO 27001 and SOC 2 compliance - owning the legal and policy layer, supporting audit cycles, and closing out action items
  • Advise product and engineering teams on privacy-by-design as we ship new features
  • Monitor the regulatory environment and flag material changes to the business

Corporate, Employment & IP (20%)

  • Handle UK employment matters: offer letters, contracts, IP assignments, restrictive covenants
  • Coordinate US and Singapore employment matters alongside external counsel
  • Maintain our IP register and advise on licensing and ownership questions as the product evolves

You've spent a few years in-house at a SaaS or tech business - or you've trained at a commercial firm and spent enough time on tech clients that you know exactly how enterprise software contracts work and how to close them. You have a clear, low-ego risk profile: you know when to hold a position and when to move on, and you never let perfect be the enemy of progress.

You bring:

  • Qualified solicitor (England & Wales), 3–6 PQE with US experience
  • SaaS or B2B tech experience - either in-house or with a significant tech client base in private practice
  • Strong commercial drafter: fast, clean, and position-led - you improve contracts, not just mark them up
  • Genuine AI literacy - you use Claude or equivalent tools in your workflow; drafting without them would feel like leaving performance on the table
  • Pragmatic risk profile - you give clear answers, not endless caveats, and you understand that a 90% answer delivered today beats a perfect answer delivered next week
  • Project management instincts - you track your matters, close your actions, and keep stakeholders informed without being chased
  • Excellent communication skills - you have the ability to interact effectively when negotiating with customers, and communicating to the business internally

Bonus points if you have:

  • Experience with multi-jurisdictional structures (UK parent, US / Singapore subsidiaries)
  • Exposure to EIS/SEIS, investor rights agreements, or post-Series A governance
  • Proptech, real estate, or financial services sector experience
  • Previous experience supporting a fundraise or regulatory due diligence process

We're building something extraordinary - and we want extraordinary people. Our benefits package goes beyond the standard startup offering, from tailored support for life's challenges to meaningful parental leave.

  • £100–120k salary per annum + bonus + meaningful equity (on a standard vesting schedule)
  • Enhanced pension contributions (5%)
  • Unlimited annual leave
  • £100 monthly wellbeing budget
  • £1,000 annual training budget
  • Electric car scheme (salary sacrifice)

Tailored support for exceptional challenges, which may include contributions to:

  • Gender-affirming care
  • Private specialists and diagnostic scans
  • ADHD / Autism diagnosis
  • IVF / fertility care
  • Therapy

Enhanced parental leave

  • 14 weeks full pay for primary caregiver (followed by statutory pay)
  • 6 weeks full pay for secondary caregiver

Flexible working , hybrid (Wednesdays in our Oxford Street office), judged on output not hours. Quarterly team weeks in London, regular travel to New York and Singapore as the business grows.
