People Operations Generalist in Kidlington

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.

The role - an honest version: 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.
• 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. Right tools. Right access. Right information. From day one. Leavers are handled cleanly and completely. Exit interviews done. Documentation in order. Systems updated. Nothing left hanging. You will also manage employment changes — promotions, team moves, performance review documentation; keeping everything accurate and on time. And you will track the data. Why do people join/leave. You will bring those insights to the People Operations Director so we keep getting better.
• 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. Keep it current. If something is not working, you will flag it and get it fixed. People Box is how we capture and manage performance reviews. You will keep it running smoothly and make sure nothing falls through the gaps. You own employment documentation end to end, across multiple jurisdictions. Contracts, amendments, compensation letters, benefits, ER documentation. All of it. People's reports are yours too. Headcount, turnover, absence. If something looks off in the data, you query it before it goes anywhere. Insights, not just numbers. And you will work closely with the People Operations Director to keep improving the systems and processes that underpin everything else. If there is a better way to do something, we want to know.
• 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. Managers rely on you for guidance that is practical and compliant. Straight answers, not policy recitals. Absence and statutory leave are managed proactively. You stay on top of cases before they escalate. Welfare checks, occupational health referrals, sensitive conversations — you handle all of it with the professionalism and care it deserves.
• People Policy, Compliance & Health & Safety: You keep us compliant, as we operate in a regulated industry. You help us stay ahead of it rather than reacting to it. You will be our Health & Safety point of contact and will need to attend audits & ensure all H&S issues run smoothly. Own Health & Safety documentation, risk assessments, and required training across the organisation. You will regularly review and update HR policies across our jurisdictions. Identify risks before they become problems. GDPR compliance across all people processes and records sits with you too. In a business operating across Ireland, the UK, the USA, and beyond, this is real multi-jurisdiction work.
• 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. You work closely with the People Operations Director to ensure our performance processes are applied consistently across a distributed workforce. You contribute actively to employee wellbeing initiatives across all our locations. You support DEI delivery and representation reporting. You also help embed inclusive practices into how we hire, onboard, and write policy.

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. BambooHR or ClickUp or PeopleBox experience is a bonus. What matters more is that people trust your data, you keep it clean, and we use it to make better decisions.
• You have experience handling a wide range of initial people ops queries independently. You also have sound experience & judgement to know how to handle each situation and the documentation needed to back it up.
• We use AI tools actively (Claude, Perplexity, ChatGPT) to streamline work. (with AI governance/usage guidance in place). We want someone who sees this as an opportunity and runs with.
• Skill gets you in the door, Will helps you thrive.
• You juggle competing priorities across operational and generalist work daily. And make sure nothing gets dropped.
• 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. If the data looks off, you ask why. If a process is broken, you fix it.
• You have a genuine interest in AI and automation. We actively use Claude, Perplexity, and ChatGPT to streamline how we work, (AI governance is in place). We want someone who sees the opportunity in that, not the obstacle.
• You have a high tolerance for ambiguity and a low tolerance for unnecessary processes. Fast-moving environments are where you do your best work. You bring energy to the pace rather than just keeping up with it.
