Through reasoned discussions and continuous feedback, we strive to improve both individually and collectively. We foster an environment of mutual trust and respect, empowering effective debate to achieve the best outcomes for our customers and team. We especially encourage members of underrepresented groups in the tech community to apply and understand that not all successful candidates will meet each requirement listed. Our interview process is unique to each role, and we value the candidate experience just as much as our customer experience. We hope your conversations with us reflect a thoughtful process that is illuminative, enjoyable, and respectful of your time. About the Role Render's mission is to eliminate the undifferentiated work that goes into building software products by offering an easy-to-use, powerful cloud platform for developer teams of all sizes. We are scaling rapidly. Our customers have created hundreds of thousands of services on our platform, and the numbers continue to accelerate. Our customers trust us to deliver a secure, reliable and performant cloud - this is our top priority as a company. By joining us at an early stage, you will design and build the cloud platform you've always wanted for yourself, and make decisions that will shape our product and company, directly impacting developers around the globe. Render builds and operates our own networking stack end-to-end. We leverage open source and industry-standard technologies, modifying and extending the core components to meet the unique reliability, performance, and scaling demands of our platform. We are looking for engineers with deep specialization in network infrastructure, particularly with experience in edge/ingress networking and Kubernetes networking internals. Areas of focus include scaling and evolving our traffic routing and load balancing systems; advancing Kubernetes and Linux networking components to support large-scale, zero-downtime operation; and exploring networking for Render's next-generation compute platforms. What You'll Do * Own Render's core network infrastructure across multiple data centers and cloud providers. Shape how networking evolves as Render rapidly scales. * Design and build customer-facing networking capabilities that give users greater flexibility in how their services connect, communicate, and how traffic is routed. * Investigate complex networking issues across the stack, from the kernel and data plane to distributed systems and edge networking. * Drive performance and reliability improvements through systematic profiling and tuning. * Partner with engineers across the company to build a platform that is stable, predictable, and secure. * Participate in our on-call rotation. Help continuously improve how we detect, respond to, and learn from incidents., Relevant Links from the Render Engineering Team * The Namespaces Scaling Trap (video podcast interview) and related article How We Found 7 TiB of Memory Just Sitting Around * SEV0 SF 2025 | Boundary Cases: Technical and social challenges in cross-system debugging * Distributing Global State to Serve over 1 Billion Daily Requests * Breaking down OpenAI's outage: How to avoid a hidden DNS dependency in Kubernetes * Kubernetes Informers are so easy... to misuse! If this role excites you but you don't meet every single requirement, we'd still love to hear from you-your unique experience might be just what we need. ## Related Videos - [How I saved 200K/yr in direct costs writing 0 code lines in K8s](https://www.wearedevelopers.com/videos/1055-how-i-saved-200k-yr-in-direct-costs-writing-0-code-lines-in-k8s) - [Creating a routing app with Google Maps API from scratch](https://www.wearedevelopers.com/videos/831-creating-a-routing-app-with-google-maps-api-from-scratch) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Embracing the Hybrid Cloud: Unlocking Success with Open Source Technologies](https://www.wearedevelopers.com/videos/883-embracing-the-hybrid-cloud-unlocking-success-with-open-source-technologies) - [A Technical Introduction to Bitcoin's 2nd Layer- The Lightning Network](https://www.wearedevelopers.com/videos/15-a-technical-introduction-to-bitcoin-s-2nd-layer-the-lightning-network) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) ## 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) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss)
