We believe in straight talk, quick decisions, strong execution and elegant solutions. Rapyd is where hard work pays off and careers take off. Join us and let’s build the future of fintech together.

We’re looking for a builder with a backend backbone—someone who can spot an opportunity, sketch a solution, and ship a working service fast. You’ll turn AI ideas into production-grade APIs and microservices, then iterate based on real data and feedback.

You’ll work at the edge of what’s possible with LLMs, RAG pipelines, and vector-based retrieval. The mission: wire up smart systems that automate workflows, elevate productivity, and make AI feel less like magic and more like reliable infrastructure.

• Design, build, and scale backend services and RESTful APIs to power AI-driven features.
• Develop and iterate on LLM-based applications, including context-aware pipelines (e.g. with vector-store retrieval).
• Own the full lifecycle: prototyping, evaluation, deployment, monitoring, and continuous iteration.
• Define KPIs, run experiments, and optimize systems based on metrics and data.
• Collaborate across product, data, and engineering to translate ideas into robust, shippable systems.
• Stay current with the evolving LLM/agent ecosystem and rapidly apply new tools or protocols (e.g., MCP).

• 5+ years of professional software development experience with a strong backend focus.
• Experience with advanced LLM workflows: prompt engineering, inference optimization, fine-tuning, and evaluation.
• Demonstrated experience integrating generative models with external knowledge (via RAG or similar patterns).
• Practical knowledge of embeddings and vector databases (e.g. FAISS, Pinecone).
• Experience building and scaling data pipelines for LLM ingestion and retrieval.
• Strong communication skills, bias for action, and ability to thrive in fast-paced environments.

• Previous work with agent frameworks or context protocols.
• Experience with Agile practices and a habit of staying on top of AI research and tooling.
• Hands-on experience designing and building microservices architectures.
