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
- Backend services
- Design, build, and maintain backend services in Python / Go to support our Data Platform Services - Agent runtimes on
AWS Bedrock AgentCore / ECS Fargate
, and event-driven
Lambda
handlers for our AI Platform Services
- Design and maintain our abstraction layers for for our data domain customers via custom developed utilities
- Maintain and service our infrastructure using IaC (Terraform) for our AWS accounts
•
AI / agents
- Build
RAG
pipelines and
tool-calling
AI agents for our data products: retrieval, orchestration, grounding/citations, and evaluation.
- Integrate model providers with our 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.
•
Data-platform automation
- 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.
•
Identity & security
- Implement auth and identity:
OAuth/OIDC
flows (per-user 3LO, token vaulting, session binding), least-privilege
IAM
, and secrets management.
- Enforce
multi-tenant isolation
and per-user identity/RBAC across services and agents.
•
Reliability & delivery
- 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.
