At Fifth Dimension, we’re demanding yet encouraging, valuing experimentation and thoughtful challenge. Our company values – Own It, Ship It, and Don’t Be Boring – drive us to deliver exceptional results whilst fostering a culture of innovation and continuous improvement.
A week in the life of our Legal Counsel
Monday: A new enterprise customer wants to redline our MSA. You’ve seen their playbook before – you’re back in their markup within hours, positions clearly reasoned, blockers flagged to the FD before they become deal delays.
Tuesday: ISO 27001 surveillance audit is six weeks out. You’re working through the evidence pack with our vCISO – reviewing updated policies, closing out two open action items from the last cycle, and making sure the audit trail is clean.
Wednesday: In the office on Oxford Street. You’re reviewing a new vendor DPA – the subprocessor list needs updating and their standard terms don’t meet our UK GDPR obligations. You redraft, send back, move on.
Thursday: Employment matter. A new AE offer letter needs non‑compete language tightened following a recent market hire. You turn it around same day, flag the IP assignment clause to the FD, and update the standard template so it doesn’t happen again.
Friday: Board prep support the FD needs a one‑pager on a contract’s liability position ahead of next week’s investor call. You draft it in an hour – clear, commercial, no unnecessary hedging.
This is legal at Fifth Dimension. You’re not a gatekeeper – you’re an enabler who moves fast and manages risk without slowing the business down.
What you’ll do
As our Legal 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%)
* Own our data protection function day‑to‑day: UK GDPR, US state privacy law, and cross‑border transfer mechanisms (UK/EU/US/SG)
* 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
* Draft and maintain privacy notices, DPAs, and internal data governance policies
* 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
* Support board consents, subsidiary maintenance, and cap table‑adjacent matters
* Maintain our IP register and advise on licensing and ownership questions as the product evolves
What we’re looking for
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
* Working knowledge of UK GDPR and practical experience managing compliance programmes or certification cycles (ISO 27001 / SOC 2 exposure strongly preferred)
* 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

* Electric car scheme (salary sacrifice)
