Develop and maintain WPML plugin features, investigate and resolve client issues, debug root causes, write tests and clean code, and improve product reliability based on support insights.

Develop and maintain WPML: deliver new features, strengthen components, debug and fix root causes, support clients, write tests, improve performance, and influence product roadmap.

Build and own AI/LLM-assisted product features in Ruby on Rails: integrate LLM APIs, design robust backend systems with tests, fallbacks, and safeguards, improve reliability/latency/cost/security, and debug production issues.

Senior backend engineer owning feature implementation to production, building and maintaining Ruby on Rails systems at scale, writing automated tests (unit, integration, E2E), improving performance and reliability, and collaborating with product and engineers while working autonomously during EMEA hours.

Build and own AI/LLM-assisted features in Ruby on Rails: integrate LLM APIs, implement retrieval/context patterns and prompts, ensure reliability, tests, fallbacks, performance, security, and production operability.

Design and build production AI systems: integrate OpenAI APIs, embeddings, and vector DBs; implement async pipelines and background jobs; ensure robust SQL/Postgres integrations, Docker CI, testing, logging, and monitoring; collaborate with distributed teams to turn open-ended goals into reliable production services.

Build and productionize core AI systems using Python, OpenAI APIs, embeddings and vector databases. Implement multi-agent frameworks, async pipelines, background jobs, PostgreSQL, Docker and GitLab CI. Deliver clean API integrations with strong testing, logging, and monitoring. Work independently and with distributed teams to influence architecture and ship reliable systems.

Develop and maintain WPML plugin features, diagnose and fix customer issues, improve product reliability, write tests and clean code, and deepen expertise in PHP, WordPress, performance, and modern tooling while supporting clients and influencing the roadmap.

Build and own AI/LLM-assisted product features in Ruby on Rails: integrate LLM APIs, implement prompts and retrieval patterns, ensure reliability, security, and performance, write automated tests, debug production issues, and improve system behavior over time.

Build production-ready AI systems using Python, OpenAI APIs, embeddings and vector databases. Implement async pipelines, background jobs, PostgreSQL-backed storage, Dockerized deployments with GitLab CI, and robust testing, logging, and API integrations while collaborating with distributed teams.

Develop and maintain the WPML WordPress plugin: deliver new features, strengthen components, diagnose and fix bugs, support clients, write tests, improve performance, and feed user-driven product improvements.
