⭐ About the team

DataDome's Integrations team is responsible for delivering the software components integrated by our customers to send traffic to DataDome for analysis and run challenges on clients identified as threats. The team is currently made up of 8 engineers (server-side and client-side) and is looking for a Senior Software Engineer who thrives on technical challenges and will help us develop new integrations and improve our current ones.

You will contribute to our roadmap with your teammates and work in strong collaboration with product managers and engineers across different teams (Tech, Customer Experience, Solutions Engineering).

👤 As a Senior Software Engineer (Integrations)…

🔑 You will be in charge of:

• Developing and maintaining DataDome's JavaScript Tag, our client-side integration deployed across hundreds of customer websites, with a focus on performance, resilience, security, and privacy. You will care about Core Web Vitals and the impact of our tag on customer pages. This will be your primary area of focus.
• Building and improving server-side integration modules for JavaScript-based edge platforms and runtimes such as AWS Lambda@Edge, Cloudflare Workers, Fastly Compute, Node.js, and others.
• Taking ownership of backend integration modules in other languages (Python, Go, Java, Ruby), helping customers integrate DataDome into their server-side infrastructure.
• Driving technical direction and best practices for integration components, and mentoring other engineers on the team.
• Raising the bar on code quality and release standards by driving improvements in CI/CD pipelines, testing, performance, and security across all integration components.
• Providing technical expertise to our Support and Solutions Engineering teams (Tier 2/3) to help onboard customers and resolve complex integration challenges.
• Staying on the cutting edge by monitoring technological developments in web technologies, edge computing, and server-side runtimes, and proposing improvements to our integrations accordingly.
• Managing incidents and post-incident reviews related to integration components.

• Have strong JavaScript/TypeScript skills, including familiarity with modern web standards and server-side JS runtimes.

• Are able to assess trade-offs across different integration approaches and propose solutions that scale.
• Have experience mentoring other engineers or driving technical decisions within a team.
• Care about performance, code quality, and automation.
• Have worked with CI/CD tools.

• Are willing to learn and adopt new technologies regularly.
• Have good communication skills and are fluent in English.
• Are a team player who enjoys collaborating with others and contributing to a supportive team culture.

📈 Bonus points if you:

• Have experience with edge computing platforms (Cloudflare Workers, AWS Lambda@Edge, Fastly Compute, Deno Deploy, Vercel Edge Functions, etc.).

• Have experience with cloud providers such as AWS or GCP.
• Understand the inner workings of browsers and JavaScript engines.
