What We Do

At Unthread, we’re solving an evolving, yet pervasive, challenge: support is broken. The way customer support teams and internal teams like IT, HR, and Operations manage workflows has failed to keep up with modern business needs—especially for teams living in Slack.

We’re here to change that. By deeply integrating with Slack and leveraging AI-powered automations, Unthread helps teams bring order to the chaos of support conversations—whether it’s managing external tickets or internal IT or HR requests. We don’t just automate repetitive tasks; we structure workflows, enabling teams to focus on solving real problems efficiently.

Today, forward-thinking companies like Langchain, Apollo GraphQL, HubSpot, Lemonade, and Automattic all rely on Unthread to ensure their support runs smoothly, both inside and outside their organizations.

Why Join Us?

Joining Unthread means jumping in at exactly the right time. We’ve already hit product-market fit, built a lineup of incredible clients, and are positioned for rapid growth across both internal and external support ecosystems—spaces desperately in need of innovation.

This isn’t just about AI hype (though we’re certainly pushing boundaries). By joining us, you’ll help redefine how support functions across organizations, empowering teams to be more efficient and effective.

Here’s why you’ll love working at Unthread:

Take full ownership of high-impact, full-stack features, from ideation to deployment—whether you’re automating workflows, fine-tuning our AI capabilities, or boosting performance for high-demand clients.
Lead conversations on architectural decisions as we scale, improving the performance and reliability of both customer-facing systems and internal operational workflows.
Work closely with the CTO and technical team to drive product development.

Experience deploying AI-driven solutions in production, particularly for automation or workflow improvements.

Our Tech Stack

Node.js and Typescript for modern, maintainable development.

OpenAI and other AI models that give teams superpowers, automating repetitive and tedious processes.

Work Setup

We operate in a hybrid environment that fosters both collaboration and flexibility. We gather in-office during the week with Fridays remote, plus flexibility when needed. Our focus is delivering an outstanding product, no matter where you are.

Make Your Mark from Day One: We’re a company for builders. Whether you're architecting, developing features, or influencing the product vision, your contributions will be felt immediately. There’s no back seat—every engineer takes the lead.

AI and Beyond: Our platform’s AI-driven features (such as ticket deflection and proactive insights) are just one aspect of what makes Unthread exciting. We're tackling not just AI challenges but also reimagining how IT and customer support should function fundamentally. From optimizing Slack integrations to scaling systems for a growing client base, you’ll be solving complex and impactful problems across both AI and the broader support landscape.

Immediate user impact: Few things compare to deploying a feature and seeing users respond enthusiastically. Whether it’s an HR team improving their efficiency or a support agent resolving tickets faster—**every line of code matters** and directly changes how teams operate.

A product you'll truly believe in: Unthread was born out of a lightbulb moment, when we realized we’d solved a challenge that people instantly connected with. It’s a fantastic feeling—being on a team that knows it’s building something users love—and you’ll be part of that excitement daily.

Founders in the trenches: Our founders are both technical and actively involved, rolling up their sleeves to code and develop alongside you. You’ll work with leadership that genuinely understands the technical challenges and shares your drive for innovation.

Low ego, high trust: Unthread thrives on collaborative energy. Great ideas win here; your voice will always be valued. Debates lead to breakthroughs, and red tape won’t hold you back. You’ll bring your best ideas forward, knowing that we’re all working toward the same goal.

Engage in hands-on problem-solving across both back-end and front-end environments, enhancing a robust, user-first platform.

You’ve shipped software at scale for at least 6 years, with deep experience in delivering solutions to real users with diverse needs.

You’re proficient with Node.js and comfortable with Typescript. You have experience working across both back-end and front-end frameworks—we use Angular, but experience with any modern front-end framework is welcome.

You have expertise in scalable system design. You've worked with technologies like GCP, Postgres, and microservices in production environments.

You’re excited by AI. You see it as more than hype and are eager to apply real-world AI solutions (we use OpenAI) to help teams streamline their processes.

You thrive in environments where collaboration and feedback matter, and you’re comfortable engaging in constructive discussions to reach the best outcomes.
