reimbursable expenses and accounts payable into a single product; its future-facing technology enables finance teams to control
and automate company spending at scale.

constructive critique, and speaking our minds. We understand that the best ideas don’t all come from the same place, so we
encourage diversity and inclusion in all areas of our work.
The future of fintech is about more than money, and we believe in work-life balance, continual learning, and empowered
teams. We’re also on a journey to measure and improve our environmental and social impact. From virtual cards to digital
subscriptions, our software and automation help take paper out of the equation for our customers, too.
We’re changing the world of payments, and we’re looking for an exceptional team to help us.
About the Role
Automation, Integrations, Agents, Platform, Retrieval & AI UX
As part of our Efficiency team, you will upskill and uplift every role with AI‑powered tools - automating workflows and building
secure, reliable assistants, agents, and role “digital twins.” Just like broader Payhawk we obsess over customer success, our
customers are every Hawk and every Payhawk customer, and we measure impact by adoption, task success, and time saved. We design
human‑centered AI and manage risk responsibly.
You’re a product‑minded software engineer who designs and ships end‑to‑end AI solutions: chat UIs, APIs, orchestration, data
pipelines, retrieval, evals, and guardrails. You love jumping between frontend, backend, prompts, schemas, observability, and
Kubernetes to deliver measurable time savings for Hawks.
Rigorous studies show AI assistance can raise knowledge‑worker productivity, especially for less‑experienced workers - so we
measure against hours saved and task success from day one.
