Join the Team That’s Changing Ticketing for Good

At Humanitix, we’re flipping the script on ticketing. Instead of lining the pockets of profit-driven platforms, we turn booking fees into funding for education, healthcare, and a better world — over $20.7M raised so far. We’re a social enterprise powered by purpose, and the belief that businesses can put humanity and the planet first.

We’re also a startup with a big heart. Our team culture is built on kindness, empathy, and connection, where you’re free to be yourself and do your best work — surrounded by people who care.

The Role: Senior Software Engineer, Integrations

We're growing our Integrations team and looking for a senior engineer who wants to shape how Humanitix connects to the outside world. This role sits at the centre of two big pushes: making our platform genuinely useful to AI systems and agents, and deepening our connections with external partners

You'll work on:

Extending and hardening our public API so hosts, developers, and third parties can build on top of Humanitix reliably.

Building and maintaining MCP (Model Context Protocol) integrations, enabling AI assistants and agents to interact with Humanitix data and workflows.

Growing our footprint with external partners such as Google, HubSpot, and reseller/distribution platforms (e.g. Viator/TripAdvisor via OCTO) — covering listings, sync, payments, and reconciliation.

Designing integration patterns that are secure, well-documented, and easy for both internal teams and external partners to adopt.

Owning problems end-to-end: from API design and data sync through to monitoring, error handling, and partner support.

Requirements

Be ethically aligned and genuinely inspired by our mission.

A positive sense of humour and warm heart - your colleagues are awesome human beings who bring their personality into the office.





A great work ethic and the confidence to escal problems and ask your colleagues for help.

Experience designing or consuming APIs at scale, and an interest in emerging standards like MCP and AI-agent tooling.

Experience integrating with third-party platforms/partners (payments, auth, data sync, webhooks).

Expert in documentation and testing — integration work lives or dies on clear contracts.

Understanding of design principles behind a scalable, secure application.

A curiosity and a thirst for learning.

A keen eye for design and the desire to add the extra 1% that make good integrations great.
