Forward Deployed Engineer

ABOUT US

Humaans is building the next generation of infrastructure for the workplace; software designed for companies that are scaling fast, operating globally, and pushing into new boundaries.

What started as a system of record has evolved into a broader platform for operating people globally. With Athena, our agentic AI layer, Humaans moves beyond data management into intelligent orchestration, connecting workflows across HR, IT, Finance, and Operations so organisations can act faster and with greater confidence, redefining how work gets done.

We work with ambitious teams across Europe and the US, from AI-native companies like Lovable, Poolside, Fyxer AI, and Tandem Health, to established, high-growth organisations scaling internationally and through acquisition, including Quantexa, Sellpy, Manychat, Gigs, Croud, and Threecolts. These teams don’t buy software for features,they buy leverage. The ability to run faster, cleaner, and with more control as complexity compounds.

To date, we’ve raised $20m in venture funding from some of the most respected founders, operators, and funds in technology: Lachy Groom (Physical Intelligence), Stewart Butterfield (Slack), Tobias Lütke (Shopify), Dylan Field (Figma), Jeff Weiner (LinkedIn), Claire Johnson (Stripe), Oliver Jay (OpenAI), Jay Simmons (Bond) as well as Y Combinator, Moonfire, Frontline Ventures, Pathlight Ventures, and Exor.

If you have massive ambition and want to work on a hard problem, with a small team that moves fast, at a moment when the category is genuinely up for grabs - this is it.

THE ROLE

Athena is our agentic AI platform for HR, and the category it sits in is being defined right now. There’s no settled playbook for deploying autonomous agents into real enterprises, with messy data, legacy systems and high stakes. You’ll be one of the people writing it.

Your job is to turn Athena from a product into outcomes for the companies betting on us. For each customer you work with, you’ll operate with founder-level ownership: understanding the problem, mapping it to the product, building what’s missing and owning the rollout until it’s delivering real value.

You’ll be the technical authority customers trust when the questions get hard, while working closely with our Implementation, Product and Engineering teams to turn what you learn in the field into a better product. You’ll own real customers and real deployments from day one, with the autonomy to make judgement calls about how Athena gets deployed and adopted inside complex organisations.

WHAT YOU’LL DO

- Own enterprise deployments of Athena end to end, partnering with our Implementation team to refine requirements, define use cases, map them to the product and drive successful go-lives

- Turn ambiguous customer problems into working technical solutions, making pragmatic decisions about what to configure, integrate or build

- Use AI-assisted development to ship production code, integrations and configuration quickly, shortening the traditional engineering loop from days to minutes where possible

- Act as the technical point of contact for customers throughout the relationship, earning trust across stakeholders from HR operations to senior leadership

- Drive adoption after launch by unblocking teams, resolving technical challenges and identifying new areas where Athena can create value

- Help customers get more from Athena by developing a deep understanding of model behaviour, prompting patterns, tools and agent configurations

- Bring what you learn in the field directly into the roadmap, working closely with Engineering, Product Design and our CTO to shape what we build next

- Be the technical authority during the sales process, helping prospects understand what’s possible and confidently owning the hard technical questions

- Develop the patterns and judgement for deploying agentic AI successfully inside complex organisations as we scale

WHAT WE’RE LOOKING FOR

- Multiple years of industry experience building full-stack web applications, ideally within SaaS, with the ability to ship production-quality code

- Strong TypeScript knowledge and a genuine appreciation for the language

- Experience working directly with customers and the confidence to run a room spanning operational teams through to senior leadership

- A track record of turning ambiguous business requirements into practical, working solutions

- Experience with enterprise integrations such as APIs and SSO; experience with HRIS platforms such as Workday is a strong plus

- Hands-on experience with LLMs or agentic systems, whether through prompt engineering, tool calling, evaluation or agent orchestration. You can explain where a model behaved unexpectedly, how you diagnosed it and what you did next

- Experience operating in a product or technical area where the playbook wasn’t already written, and comfort being one of the people defining it

- A strong bias towards ownership and speed, paired with t
