Employee Benefits Technical Implementation Manager
Happl, London
About the job
We’re building the next generation of employee benefits infrastructure.
At Happl, we help global teams design, manage, and scale benefits that actually work for their people by using AI, across flex allowances, benefits, insurance, recognition, and wellbeing, all in one intelligent platform.
Happl is backed by leading investors such as YCombinator, 6Degrees Capital, and more, known for backing leading companies such as Deel, Rippling, Airbnb, Coinbase, Dropbox, and most recently was awarded a place in the UK’s top 100 startups for 2026.
About the role
As an Employee Benefits Technical Implementation Manager at Happl, you'll be the person customers trust to turn their benefits strategy into a working reality. You'll own the setup of Happl across a portfolio of accounts - configuring the platform, building the eligibility and allowance logic, mapping the data, and making sure what launches actually reflects what the customer set out to deliver.
This role sits at the intersection of customer success and product. You'll work directly with HR, Reward, and Finance stakeholders to understand the strategy behind their programme - who's eligible for what, how allowances flex by grade or country, what payroll needs to see, where the exceptions live - and translate it into a clean, scalable configuration on Happl. You'll be equally comfortable walking a Reward Director through how their scheme will behave in the platform, unpicking a messy HRIS export, and building the rules logic that makes a complex global programme run without manual intervention.
