Senior Golang Backend Engineer — Scale a High-Traffic SSR Web Platform (Long-Term, Remote) We're a product team rebuilding the backend of a consumer web platform in Go with a server-rendered architecture and a modern React / shadcn front end. The product already serves a real audience (5,000+ active users, ~2M monthly page views) and we're engineering it to scale cleanly to 10–100× that load. We need a senior Go engineer who builds systems that stay fast, maintainable, and well-tested under growth — not just code that "works" until the next feature breaks it. What you'll do: - Architect and build scalable Go services (SSR + APIs) — data models, caching, concurrency, and performance under load. - Set the patterns and project structure the rest of the team follows. - Build real-time features (SSE / WebSockets; bonus for QUIC / HTTP-3 / WebTransport). - Integrate cleanly with a [login to view URL] / React / shadcn front end. - Write clean, idiomatic, well-tested and documented code — tests ship with the code. - Work in an AI-assisted workflow (Claude Code / Cursor) for speed without sacrificing quality. Must have: - 5+ years backend, with strong, idiomatic Go (goroutines, channels, context, profiling — concurrency without races/deadlocks). - Proven track record scaling production systems: caching, queues, DB/query optimization, horizontal scaling, observability. - Solid grasp of SSR web architecture and REST/GraphQL APIs. - Relational databases + Redis; comfortable reasoning about performance. - Genuine testing discipline and clean, documented code. Nice to have: - Full-stack comfort with React / [login to view URL] / shadcn. - Real-time at scale (WebSocket/SSE, QUIC/HTTP-3, WebTransport). - Experience migrating a legacy stack (e.g. Node/Vue) to a Go SSR architecture. - Analytical/columnar DBs (e.g. ClickHouse), Docker, CI/CD, cloud/k8s. Engagement: Long-term, full-time, remote. Start ASAP. To apply, please include (we read these first): - A link to a Go codebase or sample you're proud of. - One system you scaled: the bottleneck, what you changed, and the result (with numbers). - Your experience with real-time features and with AI-assisted development. - Availability and rate.

Hello, I have strong experience building scalable backend systems in Go with focus on concurrency performance optimization caching and production reliability under high traffic workloads. I have worked on real time architectures using WebSockets SSE Redis queues and scalable API services integrated with React and Next js frontends. One platform I optimized was handling heavy concurrent API traffic where database bottlenecks and inefficient caching caused high latency under load. I redesigned query flows introduced Redis caching async job queues and connection pooling which reduced average response time by over 70 percent and stabilized the platform during traffic spikes. I actively use AI assisted workflows with Claude and Cursor for scaffolding profiling test generation and architecture iteration while still manually validating concurrency logic race conditions and performance critical code paths. I focus on clean idiomatic Go with strong testing discipline structured project architecture observability and maintainable long term systems.

This project is similar like rebuilding strong highway system where traffic already exists but road must be redesigned to handle much bigger flow without slowing down. I worked before on similar backend systems where Go services handle high traffic APIs, caching layers, and real time features like WebSockets for live updates. I think starting with clear service boundaries and simple caching strategy first will make scaling easier later when traffic grows fast. As a senior backend developer with 8 years experience, I am good with Golang and can build scalable API systems with clean structure and performance focus. I expect it will take 18 days to complete this project. May I ask a question first? What is the current backend stack you are migrating from and what is the biggest performance issue right now? Waiting for your response. Vasyl

Hello, “Senior Golang Backend Engineer — Scale a High-Traffic SSR Web Platform” — scaling SSR + 2M monthly views usually fails at cache invalidation and DB contention before code complexity. I work with Go services where the first step is not feature code but defining concurrency + caching boundaries (goroutines + Redis strategy + DB query isolation). For systems like yours, I’d start by structuring the SSR/API split so render paths are cache-safe and DB calls are batchable under load. Day 1 deliverable: baseline Go service skeleton with Redis caching layer + SSR endpoint pattern + simple profiling hooks so we can immediately identify bottlenecks under simulated traffic. One key decision I’d push early: move repeated SSR data-fetching into a shared caching layer (TTL + stale-while-revalidate) to prevent stampede issues when traffic spikes 10×. Do you currently have any profiling data or is this a greenfield rebuild from the existing system? Looking forward to working with you. Srdjan

"Hi, Scaling a Go backend from 2M to 200M monthly page views is exactly the kind of engineering challenge I enjoy and have done before. Let me answer your questions directly. A Go codebase I am proud of — I built a high throughput REST API service in Go handling 50,000 requests per minute with full test coverage, clean separation of concerns and documented interfaces throughout. Happy to share the repo on our call. A system I scaled with numbers — I inherited a Node.js backend that was timing out under 800 concurrent users. I rebuilt the core data layer in Go, introduced Redis caching for hot queries, moved expensive aggregations to background workers via queues and added proper DB indexing. Result — response times dropped from 4.2 seconds to under 180ms and the system handled 8,000 concurrent users without breaking a sweat. Real time experience — I have built SSE based notification systems and WebSocket connections for live data feeds. I understand the concurrency patterns Go makes available for this and how to avoid the goroutine leaks and race conditions that kill real time systems at scale. AI assisted development I use Claude Code and Cursor daily. They speed up boilerplate and test writing significantly without touching the architectural decisions that actually matter. Available to start immediately. Rate is $25 to $30 per hour depending on scope. Happy to do a technical call and walk through architecture decisions live.

❤️ Hi there, This Go backend role is exactly the kind of systems work where clean architecture and scalability decisions matter more than just writing endpoints. Before anything, are you currently facing bottlenecks in SSR rendering, database load, or caching strategy as you scale toward higher traffic? ⭕ I recently worked on a high-traffic backend system where Go services were used to power SSR pages and API-driven content delivery for a growing consumer platform. The system handled caching layers, concurrent request processing, and optimized database queries to reduce latency under heavy load. I worked closely with frontend teams (React-based) to ensure SSR output stayed consistent, fast, and SEO-friendly while backend services scaled horizontally without breaking existing flows. One challenge was eliminating performance degradation during traffic spikes caused by inefficient DB reads and uncoordinated caching. I solved this by introducing structured caching layers, profiling goroutine usage, and redesigning a few hot paths to reduce unnecessary computation and database hits, which significantly improved response stability under load. ⭕ My experience includes working with Go concurrency patterns, Redis-based caching, API optimization, and building systems designed for predictable performance at scale. Looking forward to collaborating on a serious production system. ⭐
