Software Engineer (Full Stack)

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

We’re looking for a Software Engineer to help us build and evolve Humaans.

We obsess over the details and quality of our user-facing features and their implementation. At the same time, we move fast by creating focus and building on high-quality foundations.

This is an end-to-end engineering role where you’ll contribute across the product and stack. You’ll help shape features from definition through to release, build across frontend and backend, improve our infrastructure and integrations, and get involved wherever engineering can help us create a better product and customer experience.

WHAT YOU’LL DO

- Help shape the product from definition through to release

- Build end-to-end features across our frontend and backend

- Fix bugs, improve infrastructure and support customers when technical input is needed

- Write backend TypeScript across Node, Postgres, Redis and Kubernetes

- Write frontend TypeScript using React

- Expand our third-party integration marketplace

- Contribute to technical architecture planning as the product evolves

- Support our Sales and Marketing teams when engineering context or expertise is useful

WHAT WE’RE LOOKING FOR

- Experience building and shipping full-stack web applications, ideally within SaaS

- Good knowledge of TypeScript and an appreciation for the language

- Experience working across frontend and backend systems

- An appreciation for design, usability and digital product craftsmanship

- A product mindset and an interest in understanding the problems behind what you’re building

- Comfort working across features, bugs, infrastructure and integrations depending on what the product needs

- The ability to collaborate closely with engineers, Product and Design to take ideas through to production

- A high degree of ownership and a focus on delivering useful, high-quality experiences for customers

YOU MAY NOT BE A GREAT FIT IF

- You prefer specialising exclusively in frontend, backend or infrastructure rather than working across the stack

- You want to receive fully specified requirements rather than contributing to how features are shaped

- You’re more interested in technical complexity than the quality and usefulness of what customers experience

- You prefer working on one narrow area rather than moving between product features, infrastructure, integrations and customer problems

- You’re uncomfortable contributing outside traditional engineering boundaries when Sales, Marketing or customers need technical support

- You prefer optimising for either speed or technical perfection rather than finding the right balance between the two

OUR TECH STACK

Our tech stack today consists of TypeScript, JavaScript, React, Node, Postgres and Redis. We use GitHub for code and continuous integration to deploy to Kubernetes on Google Cloud Platform. We have a public REST API and our browser client uses a realtime WebSocket API. We obsess over details and quality of the user facing features and their implementation. Yet we move fast by creating focus and leveraging high quality foundations.

This is an in-person role. Our team comes together in the office Monday through Thursday, while most of the team collaborates in person on Mondays, Tuesdays, and Thursdays.
