Our Branch team consists of smart, humble, and collaborative people who value ownership over all. Everything we do is centered around creating a great product, team, and company that lives and breathes our motto: Build Together, Grow Together, Win Together.

About the role

Branch's event processing Platform enables Branch's Matching & Attribution, Identity graph, and Attribution. 

What you'll do

• Own the paved road: Define and evolve the common libraries, patterns, and contracts (Protobuf/Avro, gRPC/HTTP) used by sdk, gateway, matching, attribution, and identity services.
• Schema evolution at scale: Lead contract-as-code strategy (compatibility rules, registry, linting), zero/low-downtime rollouts, backfill/replay plans, and migration tooling.
• Throughput & latency: Design and tune Kafka topologies (partitions, compaction, tiered storage), producer/consumer settings, batching/compression, and hot-path code to hit p95/p99 targets.
• State & storage architecture: Model data across Aerospike/DynamoDB/FDB (keys/range design, TTL, transactions, conflict resolution); eradicate hot keys and write amps; codify backup/restore.
• Reliability & recovery: Ship idempotency/effectively-once semantics, DLQs, reprocessing pipelines, multi-region readiness, chaos tests, and disaster-recovery drills (RPO/RTO goals).
• Observability & SLOs: Standardize OpenTelemetry (traces/metrics/logs), golden signals, burn-rate alerts, and dashboards; make failure modes explainable with reason codes.
• Change safety: Feature flags, canary/blue-green, automated rollback, perf budgets in CI, and pre-merge contract/compat tests.
• Security & compliance by default: AuthN/Z between services, HMAC/signature verification at edges, PII controls, audit trails.
• Mentor & influence: Drive design reviews/RFCs, coach senior engineers, and partner with product teams as your customers.

• 8-10+ years backend/platform experience; prior tech lead on a high-throughput, low-latency data system.
• Depth in Java,Kotlin and Go. Strong async/concurrency, profiling, and performance tuning.
• Real-world Kafka expertise (idempotent producers, EOS patterns, DLQ/replay, compaction/retention).
• Hands-on with Aerospike and/or DynamoDB and/or FoundationDB (data modeling, transactions, hotspots, cost tuning).
• Avro/Protobuf + schema registry, backward/forward compatibility, and contract testing in CI.
• Production-grade observability (Graphana), on-call readiness, and incident management.
• Clear, pragmatic communication; writes crisp design docs and drives cross-team alignment.

• Identity graphs, attribution pipelines, or similar matching systems.
• Multi-region active/active, disaster recovery, chaos/latency injection.
• Stream processing (Flink/KStreams/Spark Structured Streaming) for enrichment/dedupe.
• Security hardening at the edge (rate limits, signatures, envelope encryption).

Our Stack (typical): 

Java,Kotlin,Go, gRPC/HTTP; Apache Flink, Kafka; Avro/Protobuf + schema registry, Lua, Aerospike, DynamoDB, FoundationDB; Kubernetes;

• Designing effectively-once ingestion with idempotency keys across gateways and Kafka.
• Rolling out a schema change touching 10+ services with no downtime and a reversible plan.
• Eliminating a hot partition by reshaping keys/partitions and backfilling safely.
• Building a replayer that reprocesses N hours of data without violating ordering/SLOs.
