Golang 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 hiring a core Golang developer with a quality-first mindset and a passion for software quality and continuous improvement to significantly scale our test automation coverage and build out our tooling infrastructure. 3+ years of hands-on Golang development 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, 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. Develop and maintain end-to-end automated tests using the existing Go-based framework Extend and improve the internal test automation framework Automate load testing and validation pipelines Take ownership of the Go SDK—the core library used by internal teams and customers—and its supporting ecosystem, including test suites, load-testing frameworks, health checks, and developer tooling. In the longer term - provide automation tooling (e2e tests framework too) that can be used directly by backend developers, managers, QA, etc Ultimately automate everything related to testing - turning manual and ad-hoc QA work (functional, load, healthchecks, etc) into automated, CI/CD-integrated coverage Solve complex engineering problems, perform deep root-cause analysis, and confidently navigate and debug unfamiliar code. The team has built award-winning AI products for tech corporations — devices, voice assistants, products that are actually in the world Cutting-edge tech stack: Speech Technologies, NLP, Generative AI (LLMs, diffusion models), voice-first agentic architecture with privacy-first and on-premises deployment High engineering bar and real ownership — the team cares about what actually works in production, not what looks good in a demo, and you'll see the impact of your work directly Fast career progression — a senior-heavy team and a high volume of real problems means you grow faster than you would anywhere else Startup pace with enterprise stability — real clients, real revenue, no bureaucracy Fully remote across Europe 21 vacation days + public holidays + 5 sick days Private English lessons via Preply Participation in Employee Stock Ownership Plan (ESOP)
