Qualifications

• 15+ years designing, building, and maintaining production backend services at scale.
• Expert-level Python / Go / Java for server-side development; solid grasp of relevant frameworks and the WSGI/ASGI model.
• Service & API design: REST (and/or gRPC), request/response and streaming patterns, pagination, versioning, idempotency, and backward-compatible contracts.
• Data layer: SQL and data modeling, query optimization and indexing, transactions, connection pooling; relational, warehouse (Snowflake), and NoSQL/key-value (DynamoDB) stores.
• Server-side patterns: caching strategies, background jobs/workers, queues and event-driven processing, rate limiting, retries/backoff, and timeouts.
• Performance & reliability: profiling, load handling, latency/throughput trade-offs, graceful degradation, and designing for failure.
• Observability: structured logging, metrics, distributed tracing, and debugging live production issues.
• Production AWS: ECS/containers, Lambda, IAM, API Gateway, DynamoDB.
• Infrastructure as code with Terraform; CI/CD (GitHub Actions or equivalent) and container builds.
• Distributed systems: scalable, resilient, loosely coupled services with proper failure handling.
• Security: OAuth/OIDC, authz, multi-tenant isolation, secrets management.
• Nice to have: dbt, Airflow/MWAA, Snowflake hands-on experience.

Responsibilities

• Design, build, and maintain backend services in Python/Go to support Data Platform Services — Agent runtimes on AWS Bedrock AgentCore / ECS Fargate, and event-driven Lambda handlers for AI Platform Services.
• Design and maintain abstraction layers for data domain customers via custom developed utilities.
• Maintain and service infrastructure using IaC (Terraform) for AWS accounts.
• Build RAG pipelines and tool-calling AI agents for data products: retrieval, orchestration, grounding/citations, and evaluation.
• Integrate model providers with LLM Gateway with response streaming, prompt caching, and structured outputs in an auditable way (OTeL).
• Stand up eval harnesses, guardrails, and tracing so agent quality, latency, and cost are measurable and regressions are caught before release.
• Build and maintain data-platform automation: dbt services, MWAA/Airflow orchestration, and tooling that makes data products discoverable, governed, and consumable.
• Extend the platform CLI and shared utilities that data teams use as their day-to-day interface to the platform.
• Implement auth and identity: OAuth/OIDC flows (per-user 3LO, token vaulting, session binding), least-privilege IAM, and secrets management.
• Own service reliability and delivery: Terraform, GitHub Actions CI/CD, container builds, structured logging, metrics/tracing, alerting, and cost controls.
• Set technical direction: system and API design, code review, and mentoring.

About Salesforce

Salesforce is the #1 AI CRM, where humans with agents drive customer success together. Here, ambition meets action. Tech meets trust. And innovation isn’t a buzzword — it’s a way of life. The world of work as we know it is changing and we’re looking for Trailblazers who are passionate about bettering business and the world through AI, driving innovation, and keeping Salesforce’s core values at the heart of it all.

Ready to level-up your career at the company leading workforce transformation in the agentic era? You’re in the right place! Agentforce is the future of AI, and you are the future of Salesforce.

Summary

Design, build, and maintain the backend services, APIs, data-platform automation, and AI platform / agent systems behind our data products. This is a backend-heavy role: distributed Python services, streaming. LLM/agent runtimes on AWS, RAG pipelines, and the dbt/Airflow automation that powers a Snowflake-based lakehouse.

You will work inside the Developer Experience team, whose mandate is to build the tooling, "paved paths," and automation that let internal data teams ship discoverable, governed, and consumable data products quickly and safely.

About the platform you’ll work on

Lakehouse & warehouse — Snowflake with Apache Iceberg tables in a medallion architecture (Bronze → Silver → Gold → Semantic Views).

Transformation — dbt (Cloud on Fusion) with data contracts, tag-driven governance, and automated project-evaluation checks.

Orchestration — Airflow on AWS MWAA; DAGs and schedules authored and deployed through platform tooling and CI (metadata driven).

Developer tooling — an internal CLI and reusable utilities (dbt, Iceberg operations, Snowflake load, REST API based ingestions, etc.) that abstract the platform for data teams.

Data quality & governance — Monte Carlo for data observability (monitors as code) and centralized governance (tagging, lineage, PII classification, cataloging).

AI layer — Agent/MCP/Skill deployment framework, RAG, semantic router / broker agents, over our data products and catalog metadata; conversational agents in Slack;

model access via AWS Bedrock / AgentCore, centralized LLM Gateway, and Snowflake Cortex.

Cloud & delivery — AWS (ECS Fargate, Lambda, API Gateway, DynamoDB, S3, IAM, etc.), Terraform IaC, GitHub Actions CI/CD, containerized builds, structured logging, metrics, and tracing.

Responsibilities
