Staff Backend Engineer

About the role

DOSS is building an Operations Cloud designed for physical product businesses. The platform aims to manage the flow of goods, dollars, and data in real-time across procurement, inventory, orders, fulfillment, and finance.

Responsibilities

• 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 ensuring 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 guardrails into a composable system to proactively detect anomalous behavior or risky emergent patterns.
• Mentor and shape engineering culture, partnering with product and design to transform back-office pain into elegant, resilient systems loved by operators.
