Job description

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 a Technical Account Manager at Happl, you’ll be the person customers trust to turn their ambitions into reality. You’ll own the technical implementation of Happl across a portfolio of accounts, designing the architecture, building the integrations, and making sure every deployment is intelligent, scalable, and set up to grow.

This role sits at the intersection of customer success, product, and engineering. You’ll work directly with HR, Finance, and key stakeholders to understand what they actually need, then translate those requirements into solutions that genuinely change how their teams experience benefits. You’ll be equally comfortable presenting an architecture to a CTO, configuring a complex data integration, and jumping into a troubleshooting session to get a customer unblocked.

We’re still building this function. That means there’s no rigid playbook to follow, you’ll help write it. If you’re energised by that kind of ownership, and want to shape how a category defining product gets deployed across the world, this is the role for you.

What you’ll be doing

Leading end-to-end customer implementations, from discovery and scoping through to go-live and long-term optimisation, taking full ownership of the technical relationship throughout
Designing AI-powered solutions tailored to each customer’s benefits structure, HRIS landscape, and people strategy — turning complex requirements into clean, scalable deployments
Running structured technical discovery sessions and solution workshops, mapping customer needs to Happl’s capabilities before a single line of configuration is written
Owning integrations with HRIS, payroll, and third-party platforms (including REST APIs and webhooks), ensuring seamless, reliable data flows across every customer’s tech stack
Building and automating implementation workflows using AI tools, reducing manual effort and raising the consistency and quality of every deployment
Acting as the technical escalation point during and after go-live, diagnosing root causes quickly and partnering with Engineering to drive permanent fixes
Translating what you learn across implementations into reusable assets — architecture blueprints, playbooks, and internal tooling — that make every future deployment faster and smarter
Partnering with Customer Success to ensure adoption is strong post-launch, identifying configuration gaps and opportunities that drive retention and expansion
Feeding implementation insights back to Product and Engineering with clarity and evidence, directly influencing the roadmap
Analysing configuration and usage data across your account portfolio to spot patterns, flag risks early, and surface opportunities to improve customer outcomes
Championing AI-first ways of working — actively exploring tools like Claude and ChatGPT to accelerate delivery, automate repetitive tasks, and bring smarter thinking to every customer engagement
Staying genuinely curious about HR tech, benefits trends, and the evolving AI landscape, bringing ideas that keep Happl and its customers ahead of the curve

What we’re looking for

3+ years in a Technical Account Manager, Implementation Engineer, or Technical Account Manager role within a B2B SaaS environment
A track record of owning complex, multi‑stakeholder implementations end‑to‑end — with the technical depth to design robust solutions and the communication skills to bring customers with you
Hands‑on experience with APIs, webhooks, and data integrations; comfortable diagnosing issues, building elegant solutions, and documenting them clearly for customers and internal teams
Truly AI‑native: you use tools like Claude, ChatGPT, and modern no‑code platforms in your day‑to‑day work, and you’re excited about what they unlock in implementation and customer delivery
Strong analytical and problem‑solving instincts — able to take ambiguous requirements and turn them into clear, well‑structured technical plans
An excellent communicator who adapts naturally — as confident presenting a solution architecture to a CTO as troubleshooting a configuration issue with an HR admin
Highly organised and self‑directed, capable of managing multiple concurrent implementations without compromising on quality or customer experience
Excited by the prospect of helping build a function from the ground up — you’re energised by defining how things should work, not just following an established path
Genuine curiosity about HR technology, employee benefits, and the role AI is playing in reshaping how companies support their people

If you don’t meet every requirement but feel this role fits your trajectory, we’d still love to hear from you.

What to expect

Happl is growing fast, and the pace reflects that. You’ll be working on things that don’t have established answers yet, building processes that don’t exist, making decisions with incomplete information, and iterating quickly when things change. That’s not a caveat; it’s the nature of building something totally new.

Some weeks will be brilliant. Some will be genuinely hard. Customer needs will evolve, priorities will shift, and you’ll occasionally be asked to figure out something nobody at Happl has had to figure out before. You’ll need to be resilient, resourceful, and direct, with customers, with the team, and with yourself when something isn’t working.

What you’ll get in return is real. The access, influence, and ownership available here wouldn’t exist in a larger company. Your work will be visible, your ideas will land, and the people around you will be talented, motivated, and invested in doing something that matters. If you’re energised by the challenge of building (not just operating) you’ll find a lot to love about working here.
