Flatpay is one of Europe's fastest-growing fintech companies and we've recently launched in the UK.

Role: Employee Relations Specialist
Location: 5 days a week, London
Reports to: Senior People Partner

Own and manage the day-to-day ER caseload for the UK, while shaping the policies, frameworks, and manager capability that prevent issues arising in the first place.

Responsibilities

  • Own the ER policy suite (conduct, grievance, absence, capability), reviewing and updating proactively when employment law, case precedent, or business need requires it.

  • Manage grievances and disciplinaries end to end: investigations, hearings, outcome letters, and PIPs, applying policy consistently and fairly.

  • Own the sickness and absence process end to end, stepping in on long-term or complex cases and managing occupational health referrals and reasonable adjustments under the Equality Act.

  • Partner with Legal (Neathouse Partners) on live cases and horizon-scanning: new legislation, tribunal trends, and areas of emerging risk.

  • Design and deliver manager capability programmes that build lasting confidence in handling conduct, absence, and performance conversations early.

  • Analyse caseload trends quarterly and present findings and recommended interventions to the Senior People Partner.

  • Build and maintain a case management framework that is consistent, auditable, and scalable as the business grows.

Skills and Attributes

  • Strong, current knowledge of UK employment law and the judgement to apply it commercially rather than just by the book.

  • Confident drafting investigation reports, outcome letters, and PIPs to a high standard.

  • Credible at coaching managers: builds their capability rather than simply taking the case off their hands.

  • Solution-led: escalates with options and a clear read on cost and risk.

  • Calm, fair, and decisive under pressure, comfortable owning a busy caseload and moving it at pace.

  • Comfortable presenting data-led insight and recommendations to senior stakeholders.

Our Values

At Flatpay, how we work matters as much as what we achieve.

  • Happy Humans: We bring energy to our work and create teams people enjoy being part of.

  • No Assholes: We perform at a high level while treating colleagues and customers with respect.

  • It's Our Business, Own It: Everyone takes responsibility and manages their work like it's their own business.

  • Start With No: We challenge ideas, think commercially and focus on what truly creates value.

  • Sky-High Ambitions: We set bold goals and expect people to keep raising the bar.

  • The Best Argument Wins: Titles don't decide outcomes. We debate openly to reach the best decisions.

Background and Requirements

  • Solid ER experience owning cases end to end (grievances, disciplinaries, sickness and absence) in a fast-paced environment.

  • Experience shaping or owning ER policy, not just applying it.

  • Familiarity with occupational health, reasonable adjustments, and settlement or protected conversations is a plus.

  • Experience in a high-volume, sales-led, or fast-scaling business is a plus.

  • Fluent in English.

  • Right to work in the UK (unfortunately we can't offer visa sponsorship right now).
