Backend Engineer (AI Search Project)

--Administrator--

Location: Remote / Offshore

Engagement: Full-time, 90 days (with possible extension)

About the Role
We’re building a next-generation AI-powered Search & Engagement platform that will transform static search into a guided, personalized experience.  Users will see tailored “swimlanes” of content, recommendations, and engagement features.

As a Backend Engineer, you’ll help design and implement the APIs, data flows, and integrations on AWS that power this platform. You’ll work closely with architects, frontend developers, and AI/ML engineers to deliver a secure and scalable system, all within an ambitious 90-day project timeline.

Key Responsibilities

  • Build and maintain backend services on AWS (Lambda, API Gateway) for search, feedback, tasks, and analytics.
  • Implement search and retrieval features in OpenSearch (keyword + vector search, ranking).
  • Create pipelines to enrich content with tags, lay terms, and related data.
  • Capture user interaction signals (clicks, ratings, dwell time) and process them for re-ranking and analytics.
  • Develop and document APIs for use by web, iOS, and Android clients.
  • Ensure performance targets (e.g., <2.5s retrieval time) and compliance standards are met.
  • Collaborate daily with frontend, DevOps, and product teams in an agile environment.


Required Skills & Experience

  • Solid experience building backend services with AWS (Lambda, API Gateway, DynamoDB, S3, Kinesis).
  • Hands-on knowledge of OpenSearch/Elasticsearch (indexing, search queries).
  • Experience designing and scaling APIs (REST/GraphQL, OpenAPI).
  • Familiarity with event-driven architectures and basic data pipelines.
  • Proficiency in at least one backend language (Python or Node.js preferred).
  • Understanding of secure coding practices; exposure to compliance-sensitive environments (HIPAA/PII is a plus).

Nice to Have

  • Experience with LLM-powered features or recommendation systems.
  • Familiarity with observability/monitoring tools (CloudWatch, PostHog, etc.).
  • Background in healthcare, wellbeing, or content-driven applications.

What We Offer

  • Opportunity to work on a cutting-edge AI + search + personalization platform.
  • A collaborative environment with architects, product leads, and AI specialists.
  • Fast-paced 90-day project with potential for longer-term engagement.
  • The chance to make a direct impact on real-world applications
