Senior Engineer for Centric PLM Migration (C#/.NET)

Summary
Senior Software Engineer – Centric PLM Migration (C# / .NET)

Duration: 6 months, full-time (~40 hrs/week)
Location: Remote



Overview:

Fabletics is migrating its Product Lifecycle Management system from Centric PLM 7.2 → 8.0.

A migration engine already exists in C# (.NET 4.7.2). This role is to take ownership of that codebase, stabilize it, and drive it to production.

This is not a greenfield build. You will be working with:

- real production data

- live APIs with inconsistent behavior

- complex dependency ordering across product hierarchies

You should be comfortable stepping into an incomplete system and making it reliable.



What You’ll Own:

Migration Engine (C# / .NET 4.7.2)

- Read from Centric 7.2 PostgreSQL HSE tables (ed_style, ed_colorway, ed_sku)

- Write to Centric 8.0 REST APIs (/styles, /product_colors, /skus)

- Enforce strict dependency sequencing:

-- reference data (Seasons, Categories, Size Ranges, etc.)

-- then Style → Colorway → SKU hierarchy

- Resolve foreign key dependencies across multiple reference types

- Ensure the migration is fully idempotent and safe to re-run


Data & Attribute Mapping

- Finalize ~30+ custom attribute mappings in the C8 tenant

- Resolve enum mismatches between C7 and C8

- Fix data type inconsistencies causing API failures


Reliability

- Stabilize API interactions (handling 500s, retries, edge cases)

- Improve logging (NLog) for traceability

- Ensure failed batches can be resumed safely



Success Criteria (First 6–8 Weeks)

- End-to-end migration of a representative datasets. Example: (Style → Colorway → SKU)

- No data integrity issues (no orphaned or mismatched records)

- Migration is fully re-runnable without duplication

- API interactions stabilized (no recurring unexplained failures)



Required Experience

- Strong C# / .NET experience (comfortable in existing production code)

- PostgreSQL and SQL Server (schema analysis, querying across systems)

- REST API integrations (auth flows, debugging, error handling)

- Proven experience with data migrations involving dependency ordering

- Experience building idempotent / re-runnable data pipelines


Strongly Preferred

- Centric PLM (7.x or 8.x)

- PLM / ERP integrations (e.g., SAP, BlueCherry)

- Experience working in legacy .NET environments



AI-Assisted Development

- We expect you to use AI tools effectively.

- In your proposal, include:

-- The tools you use (Copilot, Cursor, Claude Code, etc.)

-- A specific example of how AI helped you understand or modify an unfamiliar codebase

-- How you validate AI-generated code in high-risk scenarios (like migrations)



Who This Is NOT For

- Engineers without hands-on data migration experience

- Developers who primarily work on greenfield builds

- Candidates uncomfortable debugging live APIs and incomplete documentation



To Apply

Include:

- A concise example of a data migration or integration you shipped

-- What were the dependencies?

-- What broke?

-- How did you make it reliable?

- Any experience with Centric PLM or similar systems

- Your AI tool usage (with a concrete example)

- Your availability to start
