How We WorkWe share context, review ideas, pair on difficult problems, and step in when work crosses applications or specialties. We value teammates who communicate openly, document what they learn, and make the whole team stronger.
Talent does not always follow a traditional path. Skills gained through self-study, side projects, open-source work, experimentation, or experience outside a formal developer title are welcome. Tell us what you built, how you learned, and how you made something better. You do not need to check every box.

- Develop and support integrations using REST APIs, Power Platform connectors, third-party tools, and data workflows.
- Partner with the implementation team on the migration to Dynamics 365 Field Service, including data mapping, validation, testing, and issue resolution.
- Debug production issues, perform root cause analysis, and turn recurring problems into durable fixes or product improvements.
- Contribute to source control, testing, solution review, and release practices that improve quality and reduce deployment risk.
- Collaborate with service operations, IT, developers, and end users to gather requirements, review solutions, and validate outcomes.
- Support application releases, updates, user access, data quality, performance monitoring, and production stability.
- Create clear technical documentation, release notes, support guides, and training materials, and share reusable patterns and lessons with the team.

- Experience with Power Platform, including Power Apps and Power Automate.
- Hands-on programming or scripting experience in at least one language such as JavaScript, C#, PHP, Python, or PowerShell. You do not need to be an expert in every technology listed.
- Working knowledge of REST APIs, JSON, SQL/data querying, system integrations, and data flows.
- Ability to translate user needs into maintainable technical solutions and carry work from design through testing and deployment.
- Strong debugging, problem-solving, and analytical skills, including root cause analysis.
- Clear communication and collaboration, with the ability to explain technical concepts, learn unfamiliar systems quickly, and carry work to a reliable result.
- Bachelor's degree in Information Technology, Computer Science, or a related field, or equivalent practical experience gained through work, certifications, self-directed learning, or project-based experience.
Preferred Qualifications (Helpful, Not Required)- Experience with Dynamics 365 Field Service or supporting mobile workforce/service operations.
