Software Engineer — AI agents

Wildix is a global leader in UCaaS building an AI layer for business communication. The role is in the AI Agents stream, an 8-person engineering team owning the product end to end, building voice and chat agents and the platform behind them.

• Build and ship AI agent features end to end — from Node.js/TypeScript services on AWS to the interfaces used to configure, test and observe agents.
• Extend the AI agent platform — building skills, workflows, sandboxes, tools, connectors, tracing, audit and orchestration capabilities.
• Integrate and orchestrate AI providers — LLM, STT and TTS — using prompt and context engineering, tool calling, structured outputs, streaming and robust failure handling.
• Make AI quality measurable and production-ready — build evaluations, tracing and monitoring while engineering for latency, reliability, cost, privacy and security.
• Drive product discovery and ownership — challenge scope, propose solutions, bring your own ideas and stay involved after release by using quality and adoption signals to iterate.
• Raise the engineering bar through code reviews, architecture decisions, knowledge sharing and collaboration across the AI Agents stream.

• 5+ years of commercial software engineering experience, with strong JavaScript/TypeScript and Node.js backend skills and confidence working across the frontend with React or equivalent.
• Hands-on experience building and shipping LLM-powered features used by real users in production.
• Practical experience with AI application patterns including prompt and context engineering, tool/function calling, structured outputs, RAG, streaming and handling non-deterministic behaviour in production.
• Experience making AI systems measurable and observable through evaluations, tracing, monitoring and regression detection.
• Strong production AWS experience with serverless and/or containerized environments. Our stack includes Lambda/SAM, ECS, SQS, DynamoDB, RDS and OpenSearch.
• Strong engineering fundamentals across REST/API design, WebSockets, SQL and NoSQL data modelling, caching, testing, CI/CD and production debugging.
• A strong ownership and product mindset — you take initiative, challenge assumptions, work comfortably with ambiguity and turn ideas into shipped features rather than waiting for detailed specifications.
• English B2 or above.

• Flexible Time Off — Take the breaks you need to relax, recharge, and come back inspired.
• Top-Tier Tech — Love Mac? So do we! We equip our team with the best tools for success.
• Career Growth & Development — Access to programs and events to keep you at the top of your game.
• Compensation — The total compensation for this role is between EUR 48,000 and EUR 60,000 per year.
• Well-being Support — We offer access to psychology sessions to support your mental and emotional health
