Own services in .NET 9 / C# (ASP.NET Core, minimal APIs, background workers; SignalR where needed).
Design robust schemas / queries in MSSQL and Postgres (migrations, indexing, execution plans, isolation levels, partitioning where sensible).
Model and operate Apache Cassandra 5.0 (wide-column design, partition / clustering keys), including its vector search for embedding-driven features.
Build clear REST APIs, idempotent workflows, back-pressure, and retry strategies; integrate RabbitMQ for messaging and async pipelines.
Engineer for reliability : structured logging, meaningful metrics, health checks, rate limiting, circuit breakers, graceful degradation.
Contribute to the React (JSX) console (forms, data grids, live streams). No design-heavy CSS work.
Keep security tight : OIDC / JWT, RBAC, multi-tenant isolation, secrets management; work with Cloudflare for routing / WAF.
Ship via Docker / containers and CI / CD (GitHub Actions); help finish our IaC-driven multi-cloud rollout (Azure, AWS, GCP; Terraform / Ansible / pulumi experience welcome).

Qualifications : Must-haves :

7+ years building production systems in .NET (8 / 9) / C#, owning APIs and data layers end-to-end.

Deep SQL skills across MSSQL + Postgres : schema design, performance profiling, query tuning, reading plans.

Real-world distributed systems judgment : concurrency, transactions, consistency trade-offs, back-pressure, idempotency, and failure modes.

Hands-on with RabbitMQ.

Comfortable in React (JSX) to build and iterate on internal / admin UIs.

CI / CD and Docker fundamentals; IaC mindset; ability to reason about cost / performance in multi-cloud environments.

Clear communication, thoughtful PRs, strong testing discipline, and strong system design skills and design patterns.

Nice-to-haves :

Experience with Cassandra (data modeling, partitioning, SAI / secondary indexes; bonus for vector search usage).

SignalR, GraphQL; Memcached caching;

Postgres RLS / partitioning / pgvector; MSSQL columnstore.

Secrets management (e.g., Vault), Cloudflare (Zero Trust / WAF / Workers).

Practical LLM / RAG integrations (pipelines, embeddings, vector stores).
