Job Title: Senior Software Engineer (Catalog & Data Architecture)

Location:
Remote

Reports To:
Chief Digital / Chief Technology Officer

Who We Are:
Voomi is a fast-growing eCommerce distributor transforming how HVAC and industrial supplies are purchased. As an early mover in a large, underserved market, we offer a catalog of over 1M products through a fast, streamlined online experience for contractors, pros, and DIYers. Backed by a team with deep retail, eCommerce, and technology experience, we’re building a modern platform in a category ready for digital disruption. We recently raised our Series A and are scaling quickly, with significant growth ahead and a strong focus on innovation.

The Challenge:
Suppliers send data in every format imaginable — EDI, SFTP, API, CSV, portal exports. Different naming conventions, inconsistent attributes, missing fields, conflicting specs. Your job is to build the automated machinery that takes this chaos and produces a single, high-fidelity canonical product model.

What You’ll Own:

- Onboarding Engine:
Build a highly automated framework to onboard new suppliers in days, not weeks, regardless of their tech stack.
- Product Taxonomy:
Define and evolve the core product schema — how we handle complex industrial attributes, brand hierarchies, and multi-layered categories.
- Entity Resolution & Deduplication:
Solve the "same product, different name" problem. Build the logic that identifies when two different supplier feeds describe the same item.
- Automated Enrichment:
Lead the transition from manual data entry to AI-driven enrichment — deploying LLM agents to extract technical specs, generate descriptions, and classify products at scale.
- Data Quality & Governance:
Design the system that monitors feed health, detects price and inventory anomalies, flags schema drift, and ensures bad data never makes it to the catalog.
- API Integration:
Connect to supplier systems, marketplace APIs, and internal platforms. Make unreliable third-party connections reliable.

Requirements:

- 5+ years
building and scaling data systems in production. E-commerce, supply chain, or marketplace experience preferred.
- Architectural mindset.
You don't write scripts — you build systems. You understand idempotency, state management, and how to build resumable pipelines.
- Python & SQL.
Heavy lifting in Python. Complex relational work in SQL — CTEs, window functions, JSONB, performance optimization.
- Orchestration.
Strong experience with Dagster (preferred), Airflow, or Prefect.
- Columnar databases.
Experience with ClickHouse, Snowflake, BigQuery, or Redshift.
- Transformation frameworks.
SQLMesh, dbt, or equivalent.
- API integration.
REST, webhooks, rate limiting, pagination, auth. You've connected to messy third-party APIs and made them work.
- Product sense.
You understand that data quality isn't abstract — it's the difference between a contractor buying the right part or returning a $5,000 piece of equipment.

Nice To Have:

• Experience at a product data or commerce middleware company (Feedonomics, ChannelAdvisor, CommerceHub, Salsify, or similar).
• LLM APIs in production — not prototypes. Confidence scoring, feedback loops, human-in-the-loop review.
• Experience with product matching, entity resolution, or deduplication at scale.
• Philadelphia area.

The Team

You'll work directly with the CDTO on architecture and vision and collaborate with product management and the data team. This isn't a solo IC role and it isn't managing a large org — it's a high-ownership position where you build the systems and set the technical standard.

Why Voomi

• Venture-backed and growing fast.
• Modern stack, no legacy. You're building, not maintaining.
• Small team, direct access to leadership, ship daily.
• Competitive compensation and benefits.
