At Workana, we’re looking for a Senior Developer first and foremost — someone who loves building things with code, ships clean features fast, and thrives in production environments.We’re not looking for a ‘prompt engineer’ or a data scientist. This isn’t an academic research role, and it’s not about leading an AI team. It’s about being a developer who loves to code, gets excited about using AI to improve real products, and knows how to turn those ideas into production-ready features.If you love testing a new API, wiring it into a feature, and seeing it run live, this role is for you.RequirementsWhat you’ll do
  • Build and maintain user-facing features in our stack (Node.js, React.js, PHP legacy migration).
  • Explore, test, and integrate AI tools (OpenAI, Claude, Hugging Face, embeddings, agents, etc.) into real product features.
  • Deliver fast MVPs and prototypes to validate ideas and bring value quickly.
  • Stay curious: experiment, iterate, and translate early concepts into production-ready code.
What we’re looking for
  • 5+ years as a fullstack or backend-heavy developer.
  • Strong production experience with Node.js (Express/Nest) and ideally React.js.
  • Ability to work with PHP legacy code during migration.
  • Hands-on with Docker, REST APIs, testing frameworks, and CI/CD pipelines.
  • 2+ years applying AI tools in real projects (not just experiments or theory).
  • Experience delivering MVPs quickly and iterating based on feedback.
  • A maker mindset: you balance curiosity and exploration with execution and delivery.
Mindset we value
  • You’re a developer first: clean code, working features, and impact over perfection.
  • You treat AI as a tool, not hype — and know how to make it useful.
  • You’re proactive, self-driven, and thrive in uncertain or evolving environments.
  • You enjoy being a senior voice in tech conversations while remaining hands-on.
BenefitsWhat’s in it for you
  • A high-impact senior role shaping how Workana adopts AI at scale.
  • Autonomy and ownership from day one, in a remote-first culture with no bureaucracy.
  • The chance to experiment, learn, and build meaningful features with AI that thousands of users will use.
  • A team that values speed, bold ideas, and continuous learning.
