Join the Team That's Changing Ticketing for Valuable

n

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.

n

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.

n

The Role: Senior Software Engineer, Integrations

n

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

n

You'll work on:

n

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

n

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

n

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.

n

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

n

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

n

Requirements

n

Be ethically aligned and genuinely inspired by our mission.

n

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

n





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

n

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

n

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

n

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

n

Understanding of design principles behind a scalable, secure application.

n

A curiosity and a thirst for learning.

n

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

n

Why You'll Love It Here

n

You will have JOINT OWNERSHIP to contribute and change the customer experience process & be responsible for its success

n

We do not micromanage anyone, you are trusted, have full autonomy and are treated as an adult

n

We use the absolute BEST software, tools & equipment to do our job.

n

We ONLY hire other smart, ambitious people who LOVE to learn and grow

n

As a leading team member your input will be absolutely CRITICAL to the success of the company in all areas – including design, marketing and product.

n

Our Values

n

Show up

n

We go all-in for our customers and for each other because we care about what we do. It's okay to be yourself, be vulnerable and say 'I love you'. Try it.

n

Be bold

n

Think for yourself, say what you believe and have the curiosity and courage to lead us further forward into new territory. Let's go.

n

The world is not f*cked

n

Yep, it can be a lot better, but there's no future in giving up. We create a better world by choosing positivity, investing in humanity and forging pathways to progress. Be humane.

n

Keep it weird

n

We celebrate humanity, thrive on individuality, and love all the ways we are different. Bring your true self to work and be inclusive, open and transparent.

n

This is our second home

n

The truth is we spend more of our time awake at work than anywhere else in life. We believe a truly enjoyable workplace is critical to a life well-lived.
