Satellit - Senior .Net Developer

Satellit is seeking an experienced .NET developer with Java know-how to join a multi-disciplinary team delivering digital identity and authentication capabilities for a major energy-sector engagement. The role involves building, validating and documenting reusable authentication/authorization components, contributing to deployment automation, collaborating with IT stakeholders, and participating in agile squad activities. This position follows a hybrid work model with an expectation of being on-site about two days per week and is planned to start in the mid-October to mid-November timeframe.

Full-time commitment is required.

Who are you?

What will you do? Design, implement, unit-test and document libraries, services or components that handle user authentication and authorization. Create example applications and code samples to illustrate how to integrate identity and access services into new or existing systems, and communicate these to engineering teams.

Customize and extend commercial or open-source products (for example access managers, authorization engines, API gateways, reverse proxies and directory services) and produce supporting documentation for those extensions. Improve and automate continuous integration and continuous delivery workflows, including configuration and release automation. Work closely with IT and application teams to identify integration points, diagnose issues, and resolve problems when connecting to identity fabric services.

Install and configure third-party and open-source components by following technical guides and producing any required deployment notes. Take part in squad sprint activities, including planning, execution and retrospective work. Own assigned backlog items, drive tasks to completion and report progress to the squad.

Prepare for and actively participate in meetings and workshops, tracking actions and follow-ups. Propose technical solutions that align with requirements and constraints, present them to stakeholders and refine based on feedback. Continuously acquire new technical knowledge, standards and tooling needed to fulfill assigned work.
