Senior Java Software Engineer

Duties

• Own the end‑to‑end technical architecture for a multi‑tenant, high‑throughput messaging platform: event‑driven services, template rendering, document generation, deliverability, and channel expansion
• Define service boundaries, data contracts, and platform SLOs (latency, throughput, deliverability); codify resilience (idempotency, retries, backoff, circuit breaking) and correctness (deduplication, exactly‑once where feasible).
• Lead design reviews and drive architectural RFCs/decision records; ensure documentation quality aligns with org guidelines.
• Guide modernization (e.g., Java 21 and newer, security hardening, SDLC improvements like GitHub Actions CI).
• Partner with Product to translate roadmap themes into platform epics (capacity, compliance, channel enablement); sequence tech debt with product outcomes.
• Elevate engineering standards, performance tuning, and observability (OpenTelemetry, metrics, logs, tracing).
• Collaborate with deliverability/infra teams on MTA configuration, SPF/DKIM/DMARC alignment, and reporting pipelines for at‑scale sending.

Skills

• Deep expertise in Java and JVM performance; significant experience designing event‑driven systems at millions‑per‑day scale.
• Hands‑on Spring Boot microservices, asynchronous messaging, API design, and data stores (SQL/NoSQL, caching).
• Proven track record with HA, disaster recovery, multi‑region patterns, and observability‑first design.
• Knowledge of email/SMS ecosystems (MTA, deliverability, anti‑abuse, link tracking, templating, internationalization).
• Security and compliance awareness (PII, GDPR, CAN‑SPAM), static analysis workflows (e.g., Veracode).
• Ability to influence across product/engineering; excellent written design documentation.

Nice to have

• Experience enabling new channels (RCS/WhatsApp), running canary/feature flags, and cost/perf optimization on cloud Kubernetes.
