What you'll do

  • Design and ship agentic systems (tool calling, multi-agent workflows, structured outputs) that reliably fetch, extract, and normalize data across the web and APIs.
  • Build and operate search / indexing pipelines on OpenSearch / Elasticsearch (schema design, analyzers, reindex / data migration strategies, relevance tuning).
  • Own robust web scraping : directory crawling, CAPTCHA handling, headless browsers, rotating proxies, anti-bot evasion, and backoff / retry policies.
  • Develop backend services in Python + FastAPI with clean contracts and strong observability.
  • Scale workloads on AWS + Docker (batch / queue workers, autoscaling, fault tolerance, cost control).
  • Parallelize external API requests safely (rate limits, idempotency, circuit breakers, retries, dedupe).
  • Integrate third-party APIs for enrichment and search; model and cache responses; manage schema evolution.
  • Transform and analyze data using Pandas (or similar) for normalization, QA, and reporting.
  • Pitch in across the stack : billing (Stripe), and occasional front-end changes to ship end-to-end features.

Minimum requirements

  • Hands-on experience with agentic architectures (tool calling, structured outputs / JSON, planning / execution loops) and prompt engineering.
  • Deep knowledge of OpenSearch / Elasticsearch

    • index design, analyzers, ingestion pipelines, snapshots, rolling upgrades, and

    zero-downtime reindexing / data migrations

  • Proven web scraping expertise : solving CAPTCHAs, session / auth flows, proxy rotation, stealth techniques, and legal / ethical constraints.
  • AWS + Docker in production (at least two of : ECS / EKS, Lambda, SQS / SNS, Batch, Step Functions, CloudWatch).
  • Building high-throughput data / IO pipelines with concurrency (asyncio / multiprocessing), resilient retries, and rate-limit aware scheduling.
  • Integrating diverse external APIs (auth patterns, pagination, webhooks); designing stable interfaces and backfills.
  • Strong data wrangling with Pandas or equivalent; comfort with large CSV / Parquet workflows and memory / perf tuning.
  • Familiarity with Stripe (subscriptions, metered billing, webhooks) and basic front-end changes (React / TypeScript or similar).
  • Excellent ownership, product sense, and pragmatic debugging.

    • Nice to have

  • Entity resolution / record linkage at scale (probabilistic matching, blocking, deduping).
  • Experience with Langfuse , OpenTelemetry, or similar for tracing / evals; task queues (Celery / RQ), Redis, Postgres.
  • Search relevance (BM25 / vector / hybrid), embeddings, and retrieval pipelines.
  • Playwright / Selenium, stealth browsers, anti-bot frameworks, CAPTCHA providers.
  • CI / CD, infrastructure as code (Terraform), and cost / perf observability.
  • Security & compliance basics for data handling and PII.
