Senior Backend Engineer (Data Core)

Join our team as a Senior Backend Engineer (Data Core) and play a crucial role in maintaining and evolving the systems that collect and manage over 400 million creator profiles across major social media platforms. You will design resilient services, improve the economics of data collection, and take ownership of the entire production process. Enjoy flexible working hours, unlimited paid vacation, and the opportunity to work fully remote.

• Concevoir et faire évoluer les systèmes qui collectent et maintiennent les profils de créateurs sur plusieurs plateformes.
• Concevoir des services qui gèrent l'instabilité des API tierces, les limites de taux, les pannes de fournisseurs, et les changements de plateforme.
• Améliorer la couverture et la fraîcheur des données tout en maintenant le système financièrement durable.

• Communicated clearly across teams. You can explain tradeoffs, give direct feedback, and collaborate without creating unnecessary process
• Worked autonomously on ambiguous problems. You know how to gather requirements, ask useful questions, and make progress without waiting for a perfectly specified ticket
• Worked with proxy management or request routing. You understand the practical challenges of routing high-volume traffic and navigating anti-bot systems responsibly at scale
• Built large-scale backend or data systems. You have solid experience with high-volume services where reliability, throughput, latency, and cost all matter
• Shipped systems from concept to production. You’ve owned scoping, architecture, implementation, release, operation, and iteration—not just one layer of the solution
• Taken operational ownership. You care about observability, alerting, runbooks, and what happens after deployment—not just whether the code merged
• Bonus points if you’ve worked with social-media APIs, data-quality frameworks, large-scale collection systems, or freshness and coverage monitoring. Curiosity about the creator economy helps too, but we’ll get you up to speed
• Built resilient integrations. You’ve worked with third-party APIs or other external dependencies that are rate-limited, unstable, or liable to change
• Designed distributed systems. You can reason clearly about partial failure, retries, idempotency, backpressure, scaling, and operational tradeoffs
