Software Developer - Remote

Wildix is building AI agents for business communication. The role involves building AI agent features with Node.js/TypeScript on AWS and React, integrating LLM providers, and making AI production-ready. The team is remote-first and international.

• 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.
