Core Tech Stack: Golang, Ruby on Rails, Kubernetes, PostgreSQL, modern AI tooling.

What You Have:

• 5+ years of experience shipping and operating production services in Go, Ruby, or both (preferably).
• Networking at a working level: what TLS does, what mTLS buys you and what it costs, how TCP behaves behind different types of load balancers, how the HTTP versions differ.
• Concurrency and profiling in practice: worker pools, queues, graceful shutdown, race-free shared state, and backpressure are more than just buzzwords to you — you can put a service under load, find the bottleneck, and remove it.
• Automation-first mindset: you know that hand-configured servers and manual deploys are not the way to go if you can help it.
• Working knowledge of how LLMs and agents behave in code: message structure, the system/user/tool split, tool calls, streaming, and a feel for what breaks when.
• Solid experience with AI coding assistants when the output is fully owned by you: you review what the model wrote, catch what it got wrong, and can walk a colleague through every line you merged.
• Genuine engineering curiosity — a "sit down and dig until it's understood" mindset.
• Autonomous and proactive attitude — comfortable owning a full stack slice end-to-end, surfacing problems without waiting to be asked.
• Good level of English — at least Upper-intermediate (B2).

For the Go track, additionally:

• You know the standard library well and reach for it before a framework: net/http, crypto/tls, context, goroutines and channels, the memory model.
• Real performance work behind you: allocation pressure, GC behaviour, lock contention, with pprof and flame graphs as normal working tools.

For the Ruby track, additionally:

• Rails in production at scale: tuning ActiveRecord doesn't scare you, and services you built perform fast under load.
• PostgreSQL in depth: isolation levels, avoiding deadlocks, index types, connection pooling, migrations on large tables, reading and repairing slow queries.

Nice-to-Haves:

• Kubernetes from a developer's angle: reaching a cluster, shipping manifests for your own services, port-forwarding through a debugging session.
• Hands-on MCP experience: servers or clients you built or integrated, transports, capability negotiation.
• Contributions to open-source projects.
• Bachelor’s or Master’s in Computer Science.
