Python Backend Developer · Full Remote - vigo

About LiliHo LiliHo is a B2B SaaS platform at the intersection of AI, real-time messaging, and automation. We build infrastructure that handles high-volume guest communication across multiple channels, think WhatsApp Business API, PMS integrations, Pub/Sub pipelines, and LLM-powered workflows. Our stack is Python-first, our team is international, and we move fast. The Role We're looking for a backend developer who takes ownership seriously. You'll work directly on the core product, integrating with external platforms, building reliable messaging infrastructure, and helping shape the architecture as we grow. This isn't a ticket-execution role. You'll be expected to think, challenge, and improve. You'll report directly to our CTO, with real visibility into technical decisions from day one. We use Jira for planning and Confluence for documentation. What You'll Do • Build and ship new product features following LiliHo's engineering principles • Own integrations with external platforms (PMS providers, messaging APIs, third-party services) • Design and maintain automated testing pipelines • Contribute to architectural decisions and continuous improvement of the codebase What We're Looking For Must-haves: • 4+ years of Python experience with frameworks such as Flask or FastAPI • Solid grasp of REST API design, Pydantic, Git, and Docker • Experience with integrations or solutions engineering • Strong communication and a bias toward documentation and clarity Nice to haves: • CI/CD pipelines (GitHub Actions) • LLM frameworks (LangChain, LlamaIndex, PydanticAI) and/or RAG systems • Cloud environments (Azure, GCP, AWS) and/or Terraform • Grafana, Prometheus. • Experience with messaging APIs (WhatsApp Business API or similar) • OAuth / OIDC What Makes You Stand Out You hold yourself to a high standard. You review your own PRs like a critic. You don't wait to be told what to do next you identify the problem, propose a solution, and move. You're comfortable zooming out to the system level and zooming back into the detail. You learn independently, communicate clearly, and think in terms of tradeoffs not just solutions. What We Offer • Salary band: €50,000–55,000 • Fully remote
