Software Engineer (Full Stack)

Humaans

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. 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. YOUR DAY TO DAY * Help us shape the product from definition to release * Build end to end features, fix bugs, improve infra, support customers * Write backend TypeScript in Node, Postgres, Redis, Kubernetes * Write frontend TypeScript in React * Expand our 3rd party integration marketplace * Contribute to our technical architecture planning * Support sales and marketing teams SKILLS * Multiple years of industry experience in a full stack web app development role (ideally in SaaS) * Great knowledge of TypeScript and an appreciation for the language * Appreciation for design and digital product craftsmanship * Experience collaborating directly with product teams and designers, and a proven track record of delivering value to customers or users 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. PACKAGE & BENEFITS Early stage startups can be messy – we know that. We're putting effort in providing you with the best employee experience and a quality driven environment in exchange for trusting us. * Market-leading compensation that reflects your value * 25 days paid time off each year plus public holidays * Share Options with 5-year exercise window so you don’t feel pressure to exercise if you leave * Free Thursday lunches at HQ, quarterly team events, and company offsites. * Top tier private coverage for health, vision and dental care * A new MacBook and tools you need to do your best work * Enhanced parental leave with up to 16 weeks for primary and 4 weeks for secondary * Learning & development budget WHY JOIN HUMAANS TODAY? HR tech is having its AI moment and we’re positioned to own it. Humaans started as a next-gen HRIS taking on large incumbents in a massive market. We’ve since evolved into something even bigger: an AI platform that sits across workforce data and automates the operational layer of HR entirely; the natural progression of what we’ve been building toward. The product is highly differentiated. It’s built around a structured workforce data model that makes AI reliable in an HR context, something no one else has gotten right. Customers notice the difference immediately. We’re backed by Y Combinator, Lachy Groom, Moonfire, Frontline Ventures, and operators who’ve built some of the most consequential software companies of the last decade: the founders of Slack, Figma, and Shopify, and Asana’s former CRO and Head of OpenAI International. We’re a small team with an unapologetically high bar. It shows up in the product, in how we communicate, and in the standards we hold each other to. OUR COMMITMENT TO DIVERSITY At Humaans we’re looking for genuinely good people that are transparent and emphatic. We’re committed to providing equal opportunities, a diverse and inclusive work environment, and ensuring a fair interview process for everyone. You’re welcome to apply no matter your gender, ethnicity, sexual orientation, religion, civil or family status, age, disability, or race. PRIVACY NOTICE We care about your privacy.

Software Engineer, Pub/Sub

Ably

Our everyday digital experiences are in the midst of a realtime revolution. Whether chatting alongside a livestreaming event, receiving realtime financial information, or working with colleagues in an online collaborative environment - consumers simply expect realtime digital experiences as standard. At Ably we’re not just witnessing this revolution, we’re powering it - at scale. At the heart of our mission lies a commitment to putting developers first. Ably provides a suite of products to build, extend, and deliver powerful digital experiences in realtime, delivering billions of messages for millions of devices every day and supporting organizations like Harness, EA, Panasonic and HubSpot. Working at Ably means helping to build the infrastructure and technology that will power and shape the future of the internet. The opportunity in front of us is immense. And we’d like your help. ABOUT THIS ROLE The Pub/Sub team owns the core backend that underpins Ably's entire edge messaging platform. This is a rare opportunity to work on genuinely hard distributed systems problems at planet scale; designing and improving the infrastructure that developers and their users depend on in production every day. You'll be hands-on, driving the development of new functionality and initiatives to scale and improve Ably's core Pub/Sub platform. We work in an AI-first engineering culture: AI tools are part of how we plan, prototype, and iterate - but engineers own every technical decision, and human judgment is the quality bar that everything is measured against. You can read more about the core concepts of working on a truly distributed system in our blog post here. DAY TO DAY YOU WILL * Deliver key platform functionality.  You'll work across Ably's realtime products including our low-level Pub/Sub APIs, our LiveObjects state synchronisation layer, and AI Transport, the messaging backbone purpose-built for AI agent communication, focussing on shipping new features, performance improvements, bug fixes and maintenance. * Work fluently with AI tooling. You'll use AI tools for planning, spike work, code generation, and documentation, while taking full ownership of correctness, architectural quality, and what actually ships. Fast iteration is expected; shortcuts in quality are not. * Solve hard distributed systems problems. You'll collaborate with a talented engineering team to work through genuinely interesting and challenging technical problems. * Stay driven by 'Developer First' principles. You'll work closely with other engineers to identify and address the most important problems developers face when building on Ably. * Push to see your work in customers' hands. You'll move with urgency to ship, because you care about the impact your work has on the developers and companies building on our platform. WE'D LOVE TO TALK IF YOU HAVE * A strong interest in, or direct experience with, distributed systems and large-scale infrastructure. * Experience working with or building messaging queues, pub/sub systems, or streaming systems at scale. * Extensive experience with a high-level server-side language (Node.js or Go preferred). * The ability to self-start, work through ambiguity, and make good decisions without a lot of hand-holding. * A practical relationship with AI tooling. You use it to go faster and think more clearly, and you know where to apply rigour that AI alone can't provide. * A transparent, collaborative 'build in the open' mindset. You're comfortable sharing your work publicly, whether that's writing about what you're building, talking about technical decisions, or contributing to the broader developer conversation around the problems Ably solves. * Experience in dynamic, early-stage environments where adaptability and resourcefulness are core skills. BONUS POINTS IF YOU HAVE * Experience building developer-first products. * Experience with products brought to market through a product-led growth approach. WHAT’S IT LIKE TO WORK AT ABLY? We’re tackling planet-scale problems and our ambitions are a testament to that.
