Nonprofits use Givebutter to replace multiple tools so they can launch fundraisers and events, use donation forms and donor management (CRM), send emails and text blasts - all in one place. Use of the Givebutter platform is completely free with a 100% transparent tip-or-fee model.Givebutter has been certified as a Great Place to Work(R) every year since 2021, and is the #1 rated nonprofit software company on G2 across multiple categories.Our mission is to empower the changemaker in all of us. We believe giving should be fun, so you'll want to do it again, and we also believe that work should be fun, so that you'll have the greatest impact. We are excited to hear from talented people who want to work with other talented people in making the world a butter place - and have fun along the way.### ROLE DESCRIPTIONGivebutter is hiring a Senior Software Engineer, Integrations, to join our Growth pod. Nonprofits live inside dozens of tools they already love: CRMs, accounting, volunteer platforms, AI assistants. This role decides how well Givebutter meets them there. You'll shape our public API into something builders and their AI agents actually want to reach for, and hold the partner surfaces we care about most as they grow with us.Most of this work happens in the space between two systems: reading partner docs, spiking to see what breaks, sitting on calls with external engineers, closing the ambiguity that turns \"maybe we could\" into \"here's how.\"- Democracy of code. We value equal contributions from all engineers and foster an environment of open discussion on architecture and ideas.- Autonomy in work. We keep meetings to a minimum. Engineers have the freedom to manage their own calendars and block out uninterrupted time for focused work.- Automated CI/CD. Our build and deployment processes are fully automated and hands-off, allowing engineers to focus on problem-solving through code.- Mission-driven, full stop. You'll be working with inspiring nonprofits, charities, and organizations that are making a positive impact around the world.- Peer ownership of production surfaces. You'll take an integration or an API surface and hold it, cycle over cycle, as sales, success, and product shape it further.- AI-native workflow. We use terminal-based agents (Claude Code and similar) daily. We review what they hand us. You'll have opinions about your setup, and we'll want to hear them.### We want to hear from people who...- Read someone else's API docs carefully, and know why the choices in them matter### - Care as much about the person calling the API as the person writing it- Know that a good integration keeps a nonprofit inside the tools they already love, instead of dragging them into ours- Spike, learn what breaks, and turn that into an engineering conversation without needing a project manager to translate- Get on a call with a partner engineer and come out with less ambiguity than you started- Take your development setup seriously (terminal, editor, agent) and have probably built one or two custom skills to make them work harder### Responsibilities- Own one or more of our partner integration surfaces end-to-end, and hold them coherent as sales, success, and product shape them further- Shape our public API as its audience grows to include AI agents building on behalf of nonprofits who don't code themselves- Spike, prototype, and de-risk new partnerships, including the ones we don't yet know how to build, and the ones that only ship because someone had an aha moment- Design and defend API contracts, webhook shapes, and data flows that other engineers (and other agents) will build against for years- Partner with an existing integrations lead on the surfaces they hold today, and grow into shared ownership over time- Partner with Product, Growth, Marketing, and occasionally an external partner engineer, as a natural translator between what each group needs### Requirements- 4+ years shipping production backend services, ideally on a modern web framework- Strong proficiency in PHP / Laravel, or the kind of adjacent framework fluency that ramps quickly (we won't rule you out for having lived in Rails, Django, or Spring)- Deep familiarity with REST API design, HTTP semantics, and the patterns that make an API worth building against- Solid SQL, MySQL specifically or comfortable enough with another relational database to speak to the trade-offs you've made- Experience building against real-world third-party APIs, not just the pristine documented examples- Comfortable designing async job workflows, queued work, and observable failure paths- Strong instincts around OAuth, webhooks, and the trust-boundary decisions that keep a public API safe and honest- Active use of terminal-based AI development tools (Claude Code, Cursor, or similar) with a clear review discipline for what the agent produces### - Experience contributing to on-call rotation for production services- Comfortable navigating an existing monorepo (ours is real, and PHP / Laravel is most of the backend)### Nice to have- Contributions to a public API you helped design (bonus if it survived a v2)- You've built your own AI tooling, custom skills, or agent workflows, not just used the defaults- Familiarity with the emerging surface where AI agents consume APIs on behalf of end users, and opinions about what a legible API looks like to a non-human caller- You have opinions about the difference between a specification and an implementation (OAuth 1 vs 2, JSON:API vs REST, GraphQL and what came after: any of it, all of it)### -
