[Hiring] Senior Golang Developer, Quality Engineering @Acclaim

Role Description

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.

Qualifications

• 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, 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, capable of writing efficient, low-overhead Go code that performs reliably under heavy load.
• Hands-on experience with profiling and performance tuning using pprof, benchmarks, and the execution tracer.
• Familiarity with Prometheus metrics and instrumentation.
• Hands-on experience using AI tools in day-to-day software development.

Requirements

• Experience designing and maintaining public SDKs or libraries, including Go modules, semantic versioning, and backward compatibility (Nice to Have).
• Experience with audio stream processing (Nice to Have).
• Familiarity with SIP and telephony systems (Nice to Have).

Responsibilities

• 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.
• Provide automation tooling (e2e tests framework too) that can be used directly by backend developers, managers, QA, etc.
• 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.

Benefits

• 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).
