Senior Backend Developer (Go / Python)

Responsibilities:

• Scale high-throughput ingestion, asynchronous processing and low-latency APIs.
• Use profiling and realistic load tests to find bottlenecks, improve concurrency and resource use, and prove behaviour under sustained and burst traffic.
• Build dependable processing: bounded retries, idempotency, backpressure, safe recovery and clear ownership of failed or delayed work.
• Improve database queries, indexing, caching and service performance.
• Own capacity planning and cost per successful workload.
• Measure throughput alongside p95/p99 latency, error rates and infrastructure cost.
• Lead thorough design and code reviews for concurrency, data correctness, failure recovery, security, observability and test coverage.
• Validate changes with realistic load tests, safe migrations and rollback plans.

Requirements:

• You've been a Backend Lead, Tech Lead or equivalent, leading engineers while personally building high-performance production systems.
• Show measurable improvements in scale, latency, reliability and cost, plus the team outcomes from your reviews and coaching.
• Strong academic pedigree from a top engineering/computing institution, plus depth in queues, databases, caching, consistency and failure recovery.
• College examples are in the recruiter brief; shipped systems and leadership evidence remain essential.
• Production depth in at least one of Python, Go or Rust; you need not know all three.
• Hands-on cloud experience is required: GCP preferred, AWS also relevant.
• You've deployed and scaled services, owned observability and security, and improved cloud cost.
• Understand concurrency, profiling and memory/CPU tradeoffs.
• You communicate clearly, mentor through real technical work and use AI tools with review and verification.
• Experience supporting audio or AI workloads is useful, not essential.
