Senior Software Engineer; Full Stack

About us

Hi, we’re Humaans! We help globally scaling organisations transform their HR processes with a human-centric approach.

At Humaans, we want to empower People teams to create a customisable HR stack by offering flexibility and scalability to seamlessly integrate with other best in class platforms and point solutions, such as Google Workplace, Slack, Okta, Greenhouse, Lattice, Docu Sign and more. The stack enables companies to manage employee data, documents, contracts, reporting, and people processes that power your entire HR structure.

We have raised $20 million in VC funding to date. Investors include major tech players such as

• Y Combinator - Dylan Field (Figma CEO)

• Scott Belsky (Behance/Adobe)

• Jeff Weiner (Linked In CEO)

• Claire Johnson (Stripe COO)

• Des Traynor (Intercom)

• Akshay Kothari (Notion COO)

• Tobias Lütke (Shopify)

• Stewart Butterfield (Slack)

• and more…

Our journey is only at the beginning, and we’re looking for people excited about driving real impact. As a human centred company (quite literally), every team member counts - and that’s where you come in.

Our tech stack today consists of ReScript, Type Script, JavaScript, React.js, Node.js, Postgres and Redis. We use Git Hub 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 Web Socket 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. ReScript, Melange and OCaml are some of the languages that get us excited which is why we’ve ventured into exploring ReScript in our frontend stack.

• Build end to end features, fix bugs, improve infra, support customers

• Write backend Type Script in Node.js, Postgres, Redis, Kubernetes
