Most data platforms were built to feed dashboards. Ours has to feed dashboards, applications, and the AI agents we're building to let customers and our own teams dig into sensitive portfolio data far deeper than a dashboard allows - fast, governed, and auditable to the row.

We're hiring a Senior Data Platform Engineer to own the architecture of that layer. Everyone's talking about "AI-ready data infrastructure." This is the job where you actually build it.

Responsibilities

• Data as a product: You'll set up contracts, versioning, docs, SLAs and self-service onboarding, so product teams can use the data access layer without asking us every time.
• Modelling & migration: You'll design schemas for both transactional and analytical access, and lead the move of existing datasets onto them.
• AI-facing interfaces: You'll build tool definitions, scoped permissions, metadata exposure and audit trails, so agents can query data safely.
• Agent vs. pipeline judgment: You'll decide where agentic automation helps and where a deterministic pipeline is the better choice, then build the tooling to match.
• Platform health: You'll improve scalability, reliability and cost across Spark, Iceberg, Airflow and AWS.
• Governance: You'll own lineage, quality checks and isolation for client-sensitive data, whether a person or an agent is reading it.
• People & direction: You'll write and review design docs and turn requirements into epics

Requirements

• Experience in data or backend engineering, with strong Python and production API experience
• Hands-on GraphQL design (Hasura is a bonus)
• Deep relational database skills on RDS MySQL/PostgreSQL or similar: schema design, indexing, tuning
• Experience with Airflow plus lakehouse tools (Spark, Iceberg, Redshift, Athena)
• A track record of authoring and reviewing system design documents
• Real experience applying AI to engineering or data work, and daily use of AI coding tools

Nice to Have

• MCP servers or RAG pipelines
• Agent eval harnesses
• AI observability (tokens, latency, failure modes)
• LangGraph / Claude Agent SDK / OpenAI Agents SDK or your own orchestration
• Guardrails and prompt-injection defence
• Elasticsearch/OpenSearch

We Offer

• Play an instrumental role in reshaping one of the oldest industries in the world
• Learning and development assistance
• Vision and dental coverage
• Extra vacation days during winter holidays
• Flexible working hours and work-from-home option
• Company-supported mentorship and secondment programs
• Work abroad for up to 3 months with approval
