Senior .NET Engineer/Lead .Net Engineer

• EnCompass is the customer facing user experience and technical integrations for Corporate Payments customers, including UIs, APIs, webhooks, and data streams.

• Security Integration:

• The platform needs to be integrated with a new security implementation built on a framework leveraging OWI (One WEX Identity) and OAuth protocols. Familiarity with security tools such as Auth0 and a strong understanding of modern authentication methods is essential.
• Engineering Resources:

• Dedicated engineering support is required to focus solely on this integration effort. Mariah will not have bandwidth to assist, so new resources must be able to contribute immediately with minimal ramp-up.
• Legacy System Updates:

• The platform currently utilizes old SOAP services and .NET technologies. These will need to be updated to ensure compatibility with OWI integration.
• User Identity Management:

• There is a need to address data separation between service users and human users who currently share the same ID structure. This will involve a strategic split and migration of identity data.
• Platform Migration:

• The Encompass platform is undergoing a migration to OWI to ensure compliance and avoid potential risks. This is a critical priority.
• Infrastructure Context:

• The platform runs on AWS, though this is a lower priority compared to the security and identity integration efforts.

• 5-8 years of .Net Development experience
• OAuth (or similar)
• Strong API experience, ideally SOAP, but open to REST
• AWS - nice to have
• Strong unit and integration testing
