Staff Software Engineer

Tightknit is a community platform built for Slack that helps B2B teams grow engaged communities through events, gamification, SEO, and branded spaces. The Staff Software Engineer will help define architecture and product direction, own systems end-to-end, build AI workflows, interact with customers, and shape engineering operations as an early member of the team.

Responsibilities:

• Work directly with the CTO
• Define architecture, not just implement it
• Shape product direction, not just execute it
• Own systems end-to-end (design → implementation → monitoring → iteration)
• Interact directly with customers
• Build internal AI workflows to accelerate our velocity
• Help determine how engineering operates here
• Wear many hats and operate independently with high accountability
• Complete your SuperDay
• Join the Slack customer community and see how real users think
• Form strong opinions about our architecture, product gaps, and velocity constraints
• Release a small to medium-sized feature. Improve something meaningful
• Ship production code
• Own a scoped but consequential project end-to-end
• Propose improvements to our systems (engineering, AI workflows, APIs, performance, etc.)
• Start shaping how engineering should operate here — not just participating in it
• Lead a cross-cutting initiative (integration, refactor, reliability improvement, new surface area)
• Have direct customer conversations
• Make at least one architectural decision that meaningfully improves our trajectory
• Our integrations platform which connects into numerous different applications where customer engagement can happen
• Our embedding & retrieval architecture, powering our intelligence layer and unified semantic and keyword search
• Our AI agent for community programming

Requirements:

• This is a staff-level role, so we require at least 5+ years of experience as a full-time full-stack engineer
• You must possess strong backend engineering fundamentals and experience designing production systems
• You do not need to know all of these perfectly on day one, but you must be able to learn quickly
• Experience at an early-stage startup or working directly with founders is strongly preferred
• Experience delivering enterprise products is a bonus
• You should be able to speak to how you value the impact of community (being a member of a community group is a major plus)
