Software Development Engineer in Test / Senior Go Developer
Acclaim is a voice-first AI customer experience (CX) platform purpose-built for regulated industries including banking, fintech, healthcare, and insurance. It provides enterprises with goal-oriented AI agents that go beyond conversation to deliver agentic solutions that solve end-to-end business problems — orchestrating and executing complete customer workflows from outreach through resolution. Acclaim's solutions transform human-driven CX processes into AI-powered ones that are continuously learning and improving. About the role We're looking for a Senior SDET (Software Development Engineer in Test) with strong Go expertise to significantly scale our test automation coverage and build out our tooling infrastructure. Requirements 3+ years of hands-on Go experience, writing clean, maintainable, idiomatic code. Strong understanding of Go concurrency, including building with goroutines, channels, and synchronization primitives, as well as reasoning about race conditions, deadlocks, and graceful shutdowns. Solid grasp of modern Go idioms, including context.Context, generics, proper error handling, and structured logging. Experience with gRPC, particularly streaming RPCs. Solid understanding of networking fundamentals, including TCP, UDP, HTTP/2, and TLS. Strong testing expertise, including table-driven tests, the race detector, fuzzing, and deterministic testing of concurrent code (testing/synctest). Performance-oriented mindset. A key goal of the test suite is to serve as a load generator capable of driving a large number of concurrent streams from a single instance, so the ability to write efficient, low-overhead Go code that performs reliably under heavy load is essential. Hands-on experience with profiling and performance tuning using pprof, benchmarks, and the execution tracer—not just familiarity with the concepts. Familiarity with Prometheus metrics and instrumentation. Hands-on experience using AI tools in day-to-day software development.
Nice to Have
Experience designing and maintaining public SDKs or libraries, including Go modules, semantic versioning, and backward compatibility. Experience with audio stream processing. Familiarity with SIP and telephony systems.
