Particle Measuring Systems median: 45 days open

The posting

Particle Measuring Systems (PMS) is replacing its IFS ERP with Infor LN, delivered with Infor. Interface build and testing are under way from October 2026, with go-live targeted for July 2027.

The program includes integrations between Infor LN and the following third-party systems: Salesforce (sales and service, bidirectional), NoMuda (MES, on-premises), Modula (automated warehouse, on-premises), a trade compliance platform, a tax engine, e-invoicing and bank payment files, Workday, ADP, UPS, FedEx, PayPal Braintree and a software license service. Infor builds and tests the LN side. PMS owns the other side: third-party configuration or build, test environments, connectivity, credentials and end-to-end testing. The Business Systems team designs, prepares and builds, with one engineer close to full time on integration; build and test need a second.

Role summary

You are one of two hands-on integration engineers on the PMS side, from validating Infor’s technical specifications, through build, connectivity, testing and go-live support. You own the non-LN build and configuration (API configuration and authentication, middleware and connector configuration, file interfaces, scripts and test automation), the test environments, the connectivity between LN and each third-party system, and the tests that prove each integration works. Salesforce is administered in-house; for the two on-premises systems the vendors' professional services may be engaged for their side, in which case you coordinate and test that work. The first priority is proven connectivity for the complex integrations in test environments, followed by unit testing of the standard ones.

This is a systems-integration role, not an application development role: the craft is making an ERP and its surrounding systems talk, and proving it, on a live implementation.

Responsibilities

  • Review Infor's technical specifications (TAR-040) from the third-party side: mappings, keys, error handling, feasibility
  • Build and configure the third-party side: Salesforce with the Salesforce administrator, API and file interfaces for cloud vendors, vendor professional services for on-premises systems
  • Obtain and configure vendor test environments, credentials and service accounts; keep the inventory; maintain environment-specific endpoints, credentials and configuration across Infor's test, training and production tenants and each vendor's equivalent; keep the per-integration readiness record current
  • Prove each LN to third-party connection early in the test landscape; work with PMS infrastructure on network and security for on-premises systems
  • Trace failures across LN, middleware, network and third-party systems using API responses, logs, message queues, SQL and vendor diagnostics; own the fix or the escalation
  • Write and execute unit and end-to-end integration tests with process owners; load test data with the data migration team; log and chase defects with Infor
  • Support deployment through Infor's environments to production, cutover checks and hypercare
  • Document a hand-over note per integration
  • You support Infor's LN-side build, the Technical Delivery Architect's architecture decisions (the Business Systems Manager's until that role is in post), and process owners defining acceptance scenarios.

Experience, knowledge and skills

Required:

  • Five or more years of hands-on integration engineering between business systems: building, connecting and testing
  • REST API integration (OAuth, API keys, payloads, error handling) and file-based integration (flat file, XML, SFTP)
  • Setting up and running integration tests: environments, test data, defect tracking with a vendor team
  • Reading technical specifications critically; working with vendors to obtain documentation, sandboxes and support

Strongly valued:

  • An ERP implementation or major upgrade taken through go-live
  • Manufacturing or distribution experience: shop floor, warehouse, shipping, order-to-cash
  • An integration platform: Infor ION and its API Gateway especially valuable; Boomi, MuleSoft, Azure Integration Services or comparable count
  • Salesforce integration (Apex development is not expected; useful if you have it); exposure of on-premises systems to cloud applications
  • Automates what repeats: builds Postman or similar collections and runs them unattended; scripts test data setup and result comparison (Python, PowerShell or similar); generates and validates test files against schemas; reads integration logs and message queues to find where a transaction died; checks what actually landed with SQL. The person who succeeds here would rather write a script than click through the same test a third time

Comfortable on a small client-side team next to a much larger vendor team; documents as a habit; direct about what does not work. Drives technical issues with vendors and implementation partners to resolution without waiting to be asked.

Working relationships

Reports to the Technical Delivery Architect, who reports to the Transformation Director; until that role is in post, to the Business Systems Manager. Joins a small team of builders: an Enterprise Applications Engineer close to full time on integration and a Business Systems Analyst part of the time, both of whom design, prepare and build and continue to support IFS. Works daily with Infor's integration architect and functional consultants, PMS's Salesforce administrator, process owners, vendor professional services and PMS infrastructure.

Timing, location and hours

October 2026 start, or as soon as possible thereafter; six months, with the expectation of extension through go-live (July 2027) and hypercare. Boulder, Colorado preferred; remote possible with core overlap on US Mountain time. Infor works across US and India time zones; some early or late calls. Full time.
