You can read and reason about generated code rather than shipping it blind, and you know when a problem needs your own judgment instead of a prompt. ## Description * Build and enhance 3rd party integrations: Architect and develop complex, high-volume integrations with third-party systems. * Own the integrations foundation end to end: self-serve setup, scalability, rate limiting, retries, and observability into integration health. * Debug and support live integrations: Get hands-on with debugging, setting up, and maintaining integrations in production, including direct troubleshooting on customer calls. * Scale our systems: Iterate on backend architecture to support the growing needs of thousands of users, keeping systems robust and scalable. * Ensure reliability: Guarantee applications are reliable, well-instrumented, and free from bugs, with clear ownership of where and how integration health is monitored. * Strategic participation: Help shape product and architecture strategy, bringing informed perspective on the tools, practices, and platform decisions the team relies on daily. * Cross-functional collaboration: Work closely with product, design, and customer success to ship and support integrations with real users. ## Related Videos - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Web APIs you might not know about](https://www.wearedevelopers.com/videos/281-web-apis-you-might-not-know-about) - [Why make use of an integration platform in today's software developments and infrastructure?](https://www.wearedevelopers.com/videos/758-why-make-use-of-an-integration-platform-in-today-s-software-developments-and-infrastructure) - [Delay the AI Overlords: How OAuth and OpenFGA Can Keep Your AI Agents from Going Rogue](https://www.wearedevelopers.com/videos/1637-delay-the-ai-overlords-how-oauth-and-openfga-can-keep-your-ai-agents-from-going-rogue) - [Trunk-Based Development at Scale: Real-World Insights from a High-Traffic Luxury E-Commerce Platform](https://www.wearedevelopers.com/videos/1435-trunk-based-development-at-scale-real-world-insights-from-a-high-traffic-luxury-e-commerce-platform) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development)
