----------------------------------------

Core Experience

* 7+ years of professional experience in backend software development, with a significant focus on building and operating microservices in a production environment.

* Proven ability to work with and contribute to large-scale, distributed systems.

* Experience with cloud platforms (AWS, Azure, or GCP) for deployment, monitoring, and scaling.

----------------------------------------

Desired Qualifications

Process & Tools

* CI/CD: Experience setting up and maintaining automated deployment pipelines

* Observability: Proficiency with monitoring and logging tools

* Source Control: Expertise in Git and collaborative workflows

Architecture & Design

* Familiarity with event-driven architectures and streaming data processing

* Experience with security best practices in API design (e.g., OAuth 2.0, JWT, input validation)

* Knowledge of performance tuning and optimization techniques for both Python and Go applications

----------------------------------------

Key Responsibilities

* Design, implement, and maintain scalable and reliable backend microservices using Go

* Collaborate with product managers and front-end teams to define API specifications and integration points

* Ensure services are deployed, monitored, and scaled efficiently in a Kubernetes environment

* Participate in code reviews, design discussions, and planning sessions

* Troubleshoot and resolve complex production issues, ensuring high availability and performance

* Drive continuous improvement in development processes, tooling, and infrastructure

----------------------------------------

Must-have skills for a Senior Backend / Microservices Engineer (owner-level)

Production microservices ownership (not just “worked on”)

* Has owned at least 1–2 services end-to-end (design → build → deploy → on-call → incident fixes → scaling)

* Comfortable with service boundaries, APIs, versioning, backward compatibility, SLAs/SLOs

System design & architecture (senior bar)

* Can design systems with tradeoffs: latency, throughput, cost, reliability

* Patterns: idempotency, retries, timeouts, circuit breakers, async workflows, queues, eventual consistency

* Data design: relational vs NoSQL, caching, indexing, migrations, multi-tenant considerations (if relevant)

Strong debugging & problem-solving in real-world scenarios

* Can take an ambiguous production issue and drive it to resolution

* Uses a structured approach: reproduce → isolate → instrument → hypothesis → validate → fix → prevent

Linux fundamentals (practical, daily-use)

* Confident with commands/tools like: ps/top/htop, journalctl, systemctl, netstat/ss, lsof, curl, grep/sed/awk, strace (bonus), log parsing

* Understands networking basics (DNS, TLS, ports, timeouts)

Docker + container runtime competence

* Can explain Dockerfiles, layers, multi-stage builds, image size/security

* Debug containers: env vars, volumes, entrypoints, networking, resource limits

Observability / logging / diagnostics

* Strong in structured logging, correlation IDs, trace context

* Metrics + tracing + logs as a system

* Datadog experience is a must-have , or a very credible equivalent (Prometheus/Grafana + OpenTelemetry + ELK) with proof they can ramp fast

Platform maturity

* CI/CD, release processes, rollback strategies

* Basic security and reliability hygiene (secrets mgmt, least privilege, rate limiting)
