Software Engineer, Integrations

About Clay

Our mission is to help organizations turn any growth idea into reality.

We see growth as a creative practice, not a formula. Finding and reaching your best-fit customers takes unique ideas and constant iteration. As AI makes execution faster and tactics easier to copy, creativity is the only lasting advantage. We're already helping thousands of customers — including Anthropic, Waste Management, Figma, and Ramp — go to market with unique data, signals, and AI research.

In 2025, we crossed $100M in revenue and raised a $100M Series C at a $3.1B valuation, backed by world-class investors including Sequoia, CapitalG, and First Round. We also completed our first first employee tender offer and launched a community equity round, for our customers, agency partners, and club members.

Some things to know about us:

• Our community includes 11,000+ customers, 150+ integration partners, 125+ agencies, 50+ Clay clubs, and 30k members on Slack.

• Our culture is unique inside and outside of work. Our team members are also DJs, activists, writers, clowns, marathoners, skydivers, psychedelic therapists, social workers, and more.

• All employees can work for free with world-class coaches who specialize in creativity, management, and more.

• Our operating principles — including negative maintenance and non-attached action — guide our work. Read more about them here.

Software Engineer, Integrations @ Clay

As a software engineer on our integrations team, you’ll play a key role in building and scaling the data enrichments that are a cornerstone of our product. You’ll become an expert in building great 3rd party integrations, contributing to best practices around designing, developing, and maintaining our 100+ integrations that customers rely on every day. You’ll improve the scalability and functionality of our integration system, including our authorization, rate limiting and queueing systems for integrations. Putting on your product hat, you’ll also have the opportunity to improve the fullstack data enrichment user experience for our customers.

This is an opportunity to simultaneously ship code daily that directly unlocks new customer use cases, shape the architecture of our integrations system, and support other engineers on the team.

What You’ll Do

• Design & ship new integrations with data providers who range from well-documented REST APIs to hand-rolled custom data solutions, webhooks and SQL databases.

• Improve the integrations framework and infrastructure. You’ll improve the full-stack integrations system components such as account authorization, rate limiting and request queueing, and contribute to new ones like a data file ingestion and serving system. You’ll also contribute to ways in which we can make it easier to build and maintain new integrations.

• Work cross-functionally with other teams in engineering, partnerships, customer success, and sales to understand customer needs, respond to feedback, and measure success. This includes explaining technical concepts to both other engineers and nontechnical folks at the company.

• Debug and improve existing integrations. You’ll take ownership of integrations from start to finish, including iterating on feedback and maintaining their evolution over time.

• Partner with product managers and customers to design and deliver new customer-facing features. You’ll help shape custom user experiences tailored to integrations, drawing on strong product sense and the ability to translate customer feedback and use cases into practical solutions.

What You'll Bring

• You have experience with APIs, either building integrations with 3rd party APIs or building public APIs of your own.

• You have a proven track record of execution. You have 2+ years of hands on software engineering experience building world-class products and shipping quickly.

• You are an empathetic communicator. You express nuanced ideas clearly at different levels of abstraction for different audiences. In disagreements, you prioritize curiosity over confrontation, making sure everyone feels heard and understood. You enjoy mentoring peers and providing feedback on their code & technical designs.

• You’re familiar with our current tech stack or can learn unfamiliar technologies quickly. For integrations the primary stack is Typescript, Node.js, AWS Lambda, SQL, and React.

• Bonus: You have experience designing scalable distributed systems. You’re experienced with distributed systems principles like rate limiting and queueing, serverless computing, and data ingestion and serving.

• Bonus: you understand sales and marketing workflows and are familiar with sales and marketing APIs.
