Project Brief

We’re building a cloud‑native data infrastructure powering AI‑driven products— from ingestion pipelines and vector search to MCP‑based integrations and multi‑tenant architectures. You’ll own the design, deployment, and reliability of data pipelines end‑to‑end, working across AWS, Terraform, and Pinecone in a fast‑moving environment where architectural decisions matter and ownership is real.

Must‑Haves

Strong Python skills — Lambda functions, scripting, API consumption, and data processing pipelines

Hands‑on AWS experience across: Lambda, S3, API Gateway, ECS/Fargate, Secrets Manager, Cognito, Cloud Watch, and SQS + DLQ

Terraform for infrastructure‑as‑code — remote state with S3 + DynamoDB, modular resource definitions, and multi‑environment management

Docker — containerization, Dockerfile hardening, and ECS task image builds

Pinecone — index creation, namespace design for multi‑tenancy, metadata schema, upsert logic, and hybrid search configuration

Experience with embedding models and ETL/data transformation pipelines

MCP protocol experience — FastMCP SDK, Streamable HTTP transport, tool definition

REST API consumption — Cognito‑authenticated requests, response parsing, and S3 persistence

Git/Git Hub — trunk‑based branching, semantic PRs, and branch‑per‑feature workflows

JSON schema design for pipeline service contracts and API response structures

Retry and error handling patterns — exponential backoff and failure architecture

Clear English communication and ability to work independently with minimal supervision

Nice to Have

Incremental update and change detection logic for pipeline efficiency





Cloud Watch alarm design and pipeline health dashboards

Content‑hash deduplication for embedding cost optimization

Lambda memory and concurrency tuning

VPN site‑to‑site configuration

Lang Chain / Lang Graph experience

Prompt engineering fundamentals

Git Hub Actions — CI/CD pipeline setup and deployment automation

Marketing Business Acumen

What You Will Do

Design, build, and maintain cloud‑native data pipelines across AWS Lambda, S3, ECS/Fargate, and SQS

Manage and evolve infrastructure‑as‑code using Terraform across multiple environments

Build and optimize vector search workflows in Pinecone — including multi‑tenant namespace design, metadata schemas, and hybrid search

Develop and improve MCP server integrations using FastMCP SDK and Streamable HTTP transport

Implement and harden authentication flows using AWS Cognito and Secrets Manager

Monitor pipeline health via Cloud Watch — log groups, alarms, and observability for Lambda and ECS

Apply cost modeling discipline — flag and mitigate high‑cost operations (e.g. embedding calls at scale)

Work within an established SA governance model, contributing to architectural decisions with clear documentation and standards

Collaborate with engineering and applied science teams to deliver reliable, scalable data infrastructure

Why This Could Be Your Next Big Move

Own the data foundation — You’re not maintaining legacy systems.



You’re designing the infrastructure that AI products are built on top of.

Work at the AI/data intersection — Vector search, embeddings, MCP integrations, and multi‑tenant architectures. This is where data engineering and AI meet.

☁️ Deep AWS stack — Lambda, ECS, Cognito, SQS, Secrets Manager and more — a real opportunity to broaden and deepen your cloud expertise across a full production stack.

High ownership, high impact — Fast‑moving environment where your architectural decisions shape the product directly, with visibility across the entire engineering org.

Benefits & Compensation

$[3,500] – $[5,000]/month — paid in USD, bi‑weekly via Deel

Fully Remote — work from anywhere in Latin America

Full‑time contract with a U.S. company — 6‑month initial term, full‑time conversion

️ Paid PTO — competitive package, grows with tenure

Referral Program — earn a bonus for referring talent that gets hired
