Principal Backend Engineer

Who are we

We’re building the “Terraform for operators” — an AI‑generated schema layer driving a white‑labeled data warehouse that lets physical‑goods companies evolve their systems of record as fast as their business operations change.

Think AI foundation models driving schema migrations, real‑time observability across ops/finance data, complex git versioning of schema and data changes, and workflows you compose like infrastructure code.

What you'll do

• Design the core EAV data model & schema‑as‑code platform that powers every customer’s instance, balancing extreme flexibility with transactional integrity.
• Build a Git‑style version‑control migration engine capable of rolling forward/back complex schema and data changes on live production tenants in enterprise settings.
• Engineer AI‑assisted tooling that uses foundation models to propose, validate, and apply new customer schemas and workflow definitions.
• Scale our white‑labeled data warehouse (BigQuery/Snowflake‐like) for high‑volume, low‑latency analytics and automation workloads.
• Create Terraform‑like declarative APIs & SDKs so ops teams can treat business processes as code while you ensure security, tenancy, and performance.
• Deliver end‑to‑end observability & search across supply‑chain, finance, and ops data—surfacing business logic in plain language through AI‐native search.
• Build Enterprise guard rails into a composable system to proactively detect anomalous behavior or risky emergent patterns
• Mentor and shape engineering culture, partnering with product and design to turn unsexy back‑office pain into elegant, resilient systems loved by operators.

What you're good at

• Expertise building large scale ETL on databases like Postgres, Elasticsearch, DuckDB, Memgraph (Graph DB), etc
• Using cloud services to build deploy reliable web applications
• Working in abstractions to build complex graph-based architectures that scale
