People Operations Generalist (Hybrid, Oxford UK)

Location: UK Hybrid - On site 2/3 days per week in our Oxford site (Kidlington). Occasional travel to other UK site (Exeter) and Dublin HQ (circa once/twice per quarter depending).

Right to Work: We are unable to offer UK visa sponsorship for this UK based role.

This role covers a lot of ground. It sits at an intersection of full ownership & delivery of all People Ops processes from Hire to Retire, as well as being 1st line HR support across a range of HR areas. It is genuinely fast paced and varied, occasionally chaotic, and requires someone who finds that energising rather than overwhelming. We are not precious about job titles or lanes here. If something needs doing and it sits near your world, you get stuck in. That's our culture. The role has breadth, fast pace, and real ownership. However, it also has ambiguity, shifting priorities, and days where you will need to figure things out as you go. If you are energised rather than unsettled by it, you are probably exactly who we are looking for.

What Is In It For You

• You own the full spectrum: From HR ops to generalist work, in a lean team where what you improve actually sticks. You spot something that needs fixing, you fix it, and people notice. No committee required.
• You get real career enhancement: For your career, this builds genuine breadth, fast. Working across operations, ER, compliance, and culture in a scaling business will accelerate your development in ways a larger, more siloed organisation simply cannot match.
• Your part of a mission that matters: Deciphex exists to help clinicians diagnose faster and get patients the answers they are waiting for. The People function exists to make sure the people doing that work can do it at their best.

If that sounds like the HR role you have been looking for, we would love to hear from you.

Reporting lines

Reporting & working closely with our Ireland-based People Operations Director & our lean & effective people team. Our People team is lean. This is not a specialism someone else owns. It is yours to own & drive.

What this looks like in practice:

• Onboarding, Offboarding & Employment Changes: You will own the full employee lifecycle from day one offer through to leaver. You will design, run, and continuously improve our onboarding and induction process. Every new joiner whether Dublin, UK, USA, gets a smooth, well-prepared start. Leavers are handled cleanly and completely. You will also manage employment changes — promotions, team moves, performance review documentation; keeping everything accurate and on time.
• People Operations, Systems & Documentation: You are the custodian of our people data and the engine behind our HR operations. BambooHR is your domain. Accurate. Audit-ready. Actually useful. ClickUp is how we track employment changes and manage workflows across the People team. You will live in it daily. You own employment documentation end to end, across multiple jurisdictions. Contracts, amendments, compensation letters, benefits, ER documentation. All of it.
• Employee Relations & Absence Management: You are the first point of contact for day-to-day employee relations across the business. Performance concerns, grievances, disciplinaries, absence. You handle these independently, with sound judgement and clear documentation.
• People Policy, Compliance & Health & Safety: You keep us compliant, as we operate in a regulated industry. You will be our Health & Safety point of contact and will need to attend audits & ensure all H&S issues run smoothly. You will regularly review and update HR policies across our jurisdictions.
• Performance & Development Support: You support the performance review cycle end to end. You track probation periods across the business and flag risks early, giving managers the prompt they need to have conversations before they become issues.
• Wellbeing, DEI & Culture: You contribute actively to employee wellbeing initiatives across all our locations. You support DEI delivery and representation reporting.

What You Bring

• You have a degree in HR, Business, or a related field. Or the experience that amounts to the same thing.
• You have spent at least 4/5 years genuinely owning People Operations work, not just supporting it.
• Your employment law knowledge is current and solid; UK & Ireland as a baseline. Bonus if you have worked across USA.
• You are fluent in HRIS systems and comfortable with HR technology.
• You have experience handling a wide range of initial people ops queries independently.

Skill gets you in the door, Will helps you thrive

You juggle competing priorities across operational and generalist work daily. You are autonomous. You set your own pace, manage your own workload, and do not need to be chased. You are detail-conscious and naturally curious. You have a genuine interest in AI and automation.
