Software Engineer (Integrations)

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).

🔑 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 at least 5 years of professional software engineering experience.
• Have strong JavaScript/TypeScript skills, including familiarity with modern web standards and server-side JS runtimes.
• Have solid working proficiency in at least one other backend language (Python, Go, Java, Ruby).
• Have a good understanding of web protocols and standards (HTTP, TCP, cookies, DNS, TLS).
• 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 comfortable working across different codebases, languages, and platforms rather than specializing in a single stack.
• 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.

• Have experience with edge computing platforms (Cloudflare Workers, AWS Lambda@Edge, Fastly Compute, Deno Deploy, Vercel Edge Functions, etc.).
• Have worked with CDNs, load balancers, or web servers.
• Have experience with cloud providers such as AWS or GCP.
• Understand the inner workings of browsers and JavaScript engines.
• Are familiar with ECMAScript and Web standards.
• Have experience with security topics such as CSP, iframe sandboxing, bot detection, or web application security.
• Have worked on compilers and/or parsers.
• Have prior experience in cryptography.
• Have developed your own bots.

This role is designed to grow into a Staff Engineer position within the Integrations team. You will progressively take on broader technical ownership across the team's scope, influence architectural decisions, and become a key technical reference for both internal teams and customers.

• Flex Life: This position is open to fully remote candidates based anywhere in France. You can also work from our Parisian office located next to the Opera Garnier, or go hybrid. You will receive a 500€ stipend to help you set up your ideal workspace if you work hybrid or remotely.

• A 100€ annual allowance is provided for a leisure activity of your choice in Sports or Culture.
• Annual allowance of 200€ if you come to the office by bike to cover maintenance costs.
• Professional Development: #WeAimHigh is part of our DNA, therefore we have invested in an internal Learning and Development platform and offer the opportunity to request additional training and support via your manager.
• Events & Team building: Feel the Team Spirit both virtually and onsite, with several events and workshops planned throughout the year, including an annual offsite event, quarterly online and offline events and parties, lunch & learns, and much more.
• Parent Care: Gift & care packages for parents.
