Senior Data Platform Engineer


Job overview:

As a Senior Data Platform Engineer — Agentic AI, you will design and implement the platform foundation for AI agents operating on real-world data and services at scale. This role sits at the intersection of Data Engineering, Backend Systems, and Applied AI — ideal for engineers who love ownership, reliability, and solving hard platform problems.


You will work closely with Data Science, Product, and Engineering to take agentic AI from prototype to secure, observable, production-grade systems.


This role is ideal for engineers who enjoy building production systems, collaborating cross-functionally, and owning end-to-end platform reliability — rather than focusing primarily on research or prototypes.


What You'll Do

  • Design and build scalable, reliable data pipelines and feature stores that power AI/ML & agent workflows
  • Productionize Agentic AI systems (tool-using LLM agents, workflow orchestration, retrieval, context management, guardrails)
  • Implement data-centric AI engineering best-practices: lineage, governance, testing, monitoring
  • Build server-side APIs, microservices & orchestration layers supporting AI agent workflows
  • Optimize data processing, storage, caching & latency across structured and unstructured data
  • Deploy and operate workloads across cloud environments (AWS/GCP/Azure)
  • Partner with ML engineers to enable experimentation, CICD, and observability for AI systems
  • Own platform reliability: performance tuning, alerting, SLAs
  • Establish security & compliance standards for AI-data interactions
  • Act as a senior technical contributor & mentor within the team


You'll Be Great In This Role If You Have:

Core Experience (Required)

  • 5+ years in Data/Platform/Backend Engineering
  • Strong foundations in data engineering concepts — batch, streaming, schema design, ETL/ELT, orchestration
  • Hands-on experience with Python or Node.js (server-side scripting)
  • Expertise with SQL + modern data warehouses/lakes
  • Experience building & maintaining production systems at scale
  • Strong command of cloud platforms & containerization (Docker, Kubernetes etc.)

Agentic AI & AI Platform Experience (Preferred):

Working knowledge of

  • LLM orchestration frameworks (LangChain, LlamaIndex, DSPy etc.)
  • RAG pipelines & vector databases
  • Agent-tool execution & sandboxing
  • Prompt/response handling
  • Experience deploying AI services behind APIs / microservices
  • Understanding of model & data governance, cost management, safety & guardrails

Bonus Skills

Experience with:

  • Airflow / Prefect / Dagster
  • Spark / Flink / distributed compute
  • Snowflake / BigQuery / Redshift
  • Feature stores / ML pipelines
  • Data observability platforms
  • Experimentation platforms (AB testing)

Soft Skills We Value

  • Bias for action & ownership mindset
  • Product-thinking and customer empathy
  • Ability to collaborate across data science, product & engineering
  • Comfort balancing speed with engineering rigor
  • Clear & structured communication


What We Offer

  • Work with a lean, high-impact Data & AI team
  • Ownership, autonomy & visibility
  • Supportive learning culture
  • Competitive compensation & benefits
  • Opportunity to shape the next-gen AI data platform
  • Comprehensive employee well-being benefits.
  • Free ELSA Premium courses to polish your language skills
  • Opportunity to contribute to a fast-growing, well-funded Silicon Valley startup with global impact.
