Résumé du poste

DOSS is building an Operations Cloud for real-world product businesses, delivering a flexible data model and AI-assisted tooling to automate workflows. This role focuses on an extensible EAV schema, versioned migrations, and enterprise-grade observability across supply-chain data.

You will scale analytics and build declarative APIs to empower ops teams, while mentoring engineers and collaborating with product and design to replace traditional ERPs with resilient systems.

Qualifications

• Expertise building large-scale ETL on databases like Postgres, Elasticsearch, DuckDB, Memgraph.
• Experience deploying reliable web applications in the cloud.
• Experience building graph-based architectures that scale.
• Strong communication and collaboration with both technical and non-technical teammates.
• Taking ownership of problems and pushing work forward without constant direction.
• Making sound technical decisions and understanding tradeoffs.
• Breaking down ambiguous problems and driving execution.

Responsabilités

• Design the core EAV data model & schema-as-code platform powering every customer's instance.
• Build a Git-style version-control + migration engine for live production tenants.
• Engineer AI-assisted tooling that uses foundation models to propose and apply new customer schemas.
• Scale our white-labeled data warehouse (BigQuery/Snowflake-like) for high-volume analytics.
• Create Terraform-like declarative APIs & SDKs for treating processes as code with strong security.
• Deliver end-to-end observability & search across supply-chain, finance, and ops data.
• Mentor and shape engineering culture, collaborating with product and design.

Description du poste

About Doss

DOSS is building an Operations Cloud for the real world.

A modern, AI-native platform for physical product businesses to manage the flow of goods, dollars, and data in real time, across:

• Procurement

• Inventory

• Orders

• Fulfillment

• Finance

Built to replace spreadsheet chaos and rigid, consultant-heavy ERPs. Fast time-to-value, adaptable as the business evolves.

Through our Adaptive Resource Platform (ARP) and unified operational data model, teams deploy quickly, automate workflows, and make changes without months of re-implementation.

We recently raised a $55M Series B, co-led by Madrona and Premji Invest. Participation from Intuit Ventures, Theory Ventures, General Catalyst, Contrary Capital, and Pathlight VC.

DOSS is trusted by fast-growing operators to run critical operations with speed, control, and confidence.

About the Role

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 We're Looking For

Experience

• 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

• Communicating clearly, asking thoughtful questions, and collaborating effectively with both technical and non-technical teammates.

• Taking ownership of problems, and pushing work forward without needing constant direction.

• Making sound technical decisions, understanding tradeoffs, and contributing meaningfully to complex discussions.

• Breaking down ambiguous problems, investigating root causes, designing practical solutions, and driving them through execution.

Qualities

• Team player: you bring positivity, openness, and curiosity to the team every day.

• Growth mindset: everything is an opportunity to learn and improve yourself, the team, and the company.

• Craftsmanship: you care about making something of quality.

• Pragmatic: you make the right decision based on circumstance, not theory.

• Low Ego: you work best in collaborative environments where everyone supports the team.
