About Us

We’re a boutique consultancy spinning up an AI-enabled SaaS product. Our AWS backbone—multi-AZ VPC, ECS Fargate, ALB, Terraform IaC, logging/monitoring, IAM hardening, etc. is already in place. Your brief is to layer business logic, API endpoints and a small admin UI on top of this platform, integrating an LLM-driven scoring pipeline plus a few external APIs.

What You’ll Tackle

  • Backend feature work
  • Design and ship REST or GraphQL endpoints.
  • Build multi-tenant data models and role-based workflows.
  • Trigger emails and webhooks for status changes.
  • AI / Retrieval-Augmented Generation
    • Wire existing prompts to an LLM API (OpenAI-compatible today, private model later).
    • Store embeddings in a vector store and perform RAG look-ups.
    • Surface “explanation” JSON for every model decision.
  • Cloud hand-offs
    • Deploy new services into the existing Terraform / ECS stack—extend, don’t rewrite.
    • Add CloudWatch alarms, log routes and parameter-store secrets where needed.
  • Quality & Ops
    • Write unit and integration tests and set up a lightweight CI pipeline.
    • Provide concise hand-over docs and 30 days of post-launch bug-fix cover.

    Must-Have Skills

    • Pro in Python (FastAPI) or Node.js (TypeScript / Nest)—ready to justify your pick.
    • Experience extending an AWS stack (Terraform, ECS Fargate, ALB, Secrets Manager, KMS).
    • Hands-on with LLM APIs and at least one vector database (Pinecone, Weaviate, OpenSearch, etc.).
    • Multi-tenant data design with GDPR awareness.
    • CI/CD and automated-testing mindset.

    Nice-to-Haves

    • Solution-architect background—ability to map future services and scaling paths.
    • Prior LLM fine-tuning or custom-model training.
    • Chrome-extension data capture.
    • Transactional-email tooling (SES, Postmark, Mailgun).

    Following this sprint project there will be an additional 2-3 sprint projects of similar size to follow.
