Company Overview: We are partnering with a well-funded, early-stage startup that is bringing modern AI to the enterprise service management space. Their platform lives inside Slack, turning internal help and support channels into intelligent, automated workflows — resolving employee questions faster through AI-powered ticketing, routing, and resolution. They’re backed by top-tier venture capital and notable angel investors from companies you’d recognize. If you’re passionate about creating outstanding software that delights users and want to work with cutting-edge technology, this is a great opportunity.

About the Role We’re looking for a Senior Integrations Engineer to join the core Platform team. In this role, you’ll architect, build, and scale deep integrations with Slack and Microsoft Teams — the two primary surfaces through which the platform delivers AI-powered ticketing, routing, and resolution to enterprise customers. Beyond messaging platforms, you’ll connect the product with the broader SaaS ecosystem (identity providers, HR systems, ticketing tools) and help shape the integrations infrastructure using Temporal to orchestrate complex workflows. This is a high- impact role where you’ll collaborate across product, platform, and engineering to make the product seamlessly fit into customers’ existing environments. This role is available as a part-time contract engagement with a clear path to a full-time position for the right person. We’re looking for someone who can demonstrate strong ownership and delivery from day one.
