Core Technical Requirements
Architecture & Systems
12+ years in software engineering, 5+ years leading multiple teams (managers of managers)
Deep hands-on experience designing distributed systems (event-driven, microservices, messaging queues like Kafka Pulsar)
Strong commof domain-driven design API-first development (REST, GraphQL, gRPC)
Experience with high-throughput systems (＞10k TPS) low-latency (＜50ms p99)
Programming & Core Languages
Expert-level in Java, Go, Python – live coding + system design interview required
Deep understanding of concurrency, memory management, profiling (JVM, pprof, etc.)
Cloud & Infrastructure
AWS Azure deeply (certifications preferred: AWS Solutions Architect – Professional)
Kubernetes (EKS/AKS) – must have operated production clusters, not just deployed
Infrastructure as Code (Terraform, Pulumi) – you will review modules
Data & Persistence
Distributed databases: Cassandra, CockroachDB, TiDB at petabyte scale
Relational: PostgreSQL MySQL (sharding, replication, partitioning)
Caching: Redis Memcached at scale (＞100k ops/sec)
CI/CD & Developer Productivity
Build systems: GitHub Actions, GitLab CI, Jenkins (pipeline as code)
Artifact management, feature flags (LaunchDarkly), progressive delivery (Argo Rollouts)
Observability & Reliability
Distributed tracing (Jaeger, Zipkin), metrics (Prometheus), logging (Loki, Splunk)
SLIs/SLOs, errbudgets, SRE practices (you will define enforce them)
Security
Secure SDLC, SAST/DAST (SonarQube, Snyk, Checkmarx), OWASP top 10
Identity auth (OIDC, OAuth2, JWT, mTLS)
Key Responsibilities
Own end-to-end software delivery: architecture, development, testing, canary deployments, production operations
Lead migration from monolith to microservices (strangler pattern) without downtime
Set technical direction fplatform services (payment, inventory, user, catalog) supporting $1B+ GMV
Drive engineering excellence: code reviews, testing culture (unit/integration/E2E), technical debt reduction (20% YoY)
Define enforce architectural standards: API versioning, backward compatibility, retry/backoff, circuit breakers (Resilience4j, Hystrix)
Recruit, mentor, retain staff+ engineers – you will still conduct technical interviews
Participate in on-call escalation fSev-0/Sev-1 incidents – you will debug, not delegate
What You Have Done
Successfully led migration of a legacy monolith to microservices (500+ engineers, 2+ years) in a Fortune 500 equivalent scale
Reduced MTTR from ＞60min to ＜20min across yourg
Improved DORA metrics: deployment frequency from monthly to daily, lead time from weeks to hours
Managed ＞150 engineers ＞$30M engineering budget
