About Thread

At Thread, we're transforming the IT services industry with AI-first automation. What started as a collaboration layer on top of legacy ticketing systems has evolved into something far more powerful: a platform that helps Managed Service Providers (MSPs) resolve issues before they escalate, automate repetitive work, and deliver exceptional service without relying on traditional tickets at all.

We’re building the future of AI-assisted service delivery—and we’re looking for a Principal Software Engineer to join one of our engineering teams. This is a rare opportunity to help invent tools that don’t exist yet, backed by a product-led team, real customer traction, and a deep understanding of the space.

You’ll work with a team of exceptional engineers pushing the boundaries of real-time applications, large data integrations, and AI powered automations. As a Principal Software Engineer at Thread, you will deliver an exceptional end-to-end experience for our partners and customers. You will play a crucial role in making critical decisions regarding the architecture, design, and performance of our software.

What you should have:

• Minimum of 7 years of experience in building production services and applications
• Proficiency in working with both relational and non-relational databases
• Demonstrated experience in developing clean and well-tested code
• Familiarity with unit tests, integration tests, and other forms of automated testing
• Knowledge of production monitoring processes and tools
• Experience in agile, fast-paced work environments
• Comprehensive understanding of the software life cycle, end to end
• Experience in designing and leading software projects
• Excellent skills in listening, communication, evaluation, problem-solving, multitasking, and prioritization within a high-pressure, mission-critical, and rewarding team environment
• Bachelor's degree in Computer Science or a related technology field

We would be delighted to see

• Experience in working with large-scale real-time applications
• Familiarity with AWS or Azure Cloud Services (SQS, RDS, EKS, MSK, Redis, etc)
• Experience in working with LLMs (OpenAI, Anthropic, etc)
• Expertise in modern web frameworks and languages; our current stack includes PHP (Laravel), Golang, TypeScript (React/Apollo GraphQL/Electron), and Python (LangChain)
