  • Implement safe changes and hotfixes. Build, test and deploy code and config updates through Jenkins with proper approvals and rollbacks
  • Partner with business users to understand issue impact and edge cases. Translate vague problem reports into actionable steps and clear acceptance criteria
  • Harden use case pipelines. Add input validation, timeouts, retries, circuit breakers and fallback strategies to reduce customer facing impact
  • Improve RAG quality for stability. Tune chunking, retrieval parameters, query rewriting and caching to reduce latency and errors

  • Coordinate with platform and infra teams when incidents touch OpenShift, GPUs, vLLM or NVIDIA Enterprise AI services
  • Perform safe data operations. Validate indices, manage Redis eviction strategies and handle backfills and reindex tasks with minimal risk
  • Champion secure by default practices. Enforce secrets handling, PII redaction and prompt or output guardrails
  • Lead post incident reviews with blameless RCAs and concrete corrective actions. Close the loop with business stakeholders
  • Proactively surface reliability risks and propose code or architecture changes that remove recurring failure modes

Job Requirement

  • 3 to 4 years of software engineering or SRE with at least one year supporting AI or data intensive services in production
  • Strong Python. Comfortable reading and fixing LangChain code, FastAPI or Flask services, async patterns and task queues
  • Hands on with LangChain in real projects. Chains, tools, retrievers, memory and callback handlers

  • Redis proficiency. Caching patterns, pub or sub, streams, eviction, persistence and troubleshooting latency or timeouts
  • Safety and guardrails experience. Guardrails AI configuration, schema and validator design, LlamaGuard or similar classifiers in the loo
  • CI or CD with Jenkins. Declarative pipelines, approvals, artifacts, environment promotion and rollback strategy
  • Observability depth. Prometheus metrics, Grafana dashboards, OpenTelemetry traces and logs.
  • Able to decide which signals matter and set actionable alerts
  • Solid Git. Branching, pull requests, code reviews and release tagging. Comfortable with feature flags and canary or blue green patterns
  • Working knowledge of Kubernetes and OpenShift as a strong plus. Debugging pods, logs, events and basic resource tuning
  • Familiarity with LLM serving stacks such as vLLM or NVIDIA Enterprise AI is a plus. Know how to read model server logs, timeouts and token throughput
  • Data handling discipline. Understanding of PII, masking, prompt redaction and safe logging
  • Clear communicator who can write crisp incident updates, RCAs and user facing notes

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
