Senior Infra Engineer: Networking

All Positions Senior Infra Engineer: Networking Remote (anywhere) Full-time Job description About the role About you Things to know Benefits and perks How we hire Apply for this position Section Job description About the role About you Things to know Benefits and perks How we hire Job description Our core mission at Railway is to make software engineers higher leverage. We believe that people should be given powerful tools so that they can spend less time setting up to do, and more time doing. Many infrastructure platforms simply focus on how you deploy your singular application, and not how these applications function in concert. Questions like “How do you build systems for zero downtime deployment”, “How do you do service-to-service communications”, etc are usually left up to the engineers to define. At Railway, our goal is to be an all encompassing solution to all these problems. As such, we take special care as we define our networking infrastructure. Note: Networking falls under the platform engineering umbrella. If you’re specialized, we’d love to chat! That said, we’d also like it noted you’re probably going to do a lot of non-networking + platform things “But the world would be a better place if more engineers, like me, hated technology. The stuff I design, if I'm successful, nobody will ever notice. Things will just work, and will be self-managing” - Radia Perlman About the role For this role, you will: Setup, maintain, and evolve our edge routing networking layer (Homegrown eBPF L4 proxy) Build an internal private network for dynamically meshing together services on the platform (eBPF/WireGuard) Manage baremetal rack eBGP broadcasting to create a fault tolerant, network peered, bulletproof world wide anycast network Build sophisticated-er-than-attacker DDoS mitigation strategies (yes we know it’s a cat and mouse game) Build Golang GRPC services from scratch capable of supporting millions of users, and billion+ to come. Define infrastructure that can be torn down, failed over, and reconstituted from scratch using principle of immutable infrastructure. Write Engineering Requirement Documents to take something from idea, to defined tasks, to implementation, to monitoring it’s success. Interface with our TypeScript and GraphQL to expose your microservice APIs for both internal and potentially external consumption This is a high impact, high agency role with direct effect on company culture, trajectory, and outcome. About you Experience with overlay networking technologies ( VXLAN , WireGuard, etc) Experience writing eBPF code to mux packets around a network Hands-on experience operating and troubleshooting production-grade datacenter networks A solid intuition about how long your solutions will last. All systems age. In startups, we can hope for 2-3 orders of magnitude, or 12-18mo. The tact to implement your solution, creator monitors for it’s error boundaries, and document any requirements for when you’re not around A great sense of direction and prioritization when it comes to dealing with the ambiguity of an early stage startup A sense of grit to dive into a problem, implement a solution, scale that solution, and replace it when needed A great set of communication skills for getting your point across, solution implemented, and beyond Familiarity with the Linux networking stack and its various knobs and dials that require tuning because the out of the box settings are not suitable for our scale Network latency charts excite you as you look for opportunities to make things faster/more reliable Familiarity with BGP and internet routing (understanding of L1, especially in a DC is a huge plus!)s We value and love to work with diverse persons from all backgrounds Things to know For better or worse, we're a startup; our team dynamics are different from companies of different sizes and stages. We're distributed ALL across the globe, and that's only going to be more and more distri ... (truncated, view full listing at source)
