This role is heavily focused on:
  • Building model-driven Power Apps and workflows
  • Developing API-based integrations between systems
  • Designing cloud-native solutions in Azure

The ideal candidate is someone who can turn complex business processes into simple, scalable, and maintainable automated solutions.
Key Responsibilities
Workflow Modernization (Primary Focus)
  • Replace legacy workflow systems with model-driven Power Apps and Power Automate solutions
  • Design and implement standardized automation patterns across the bank
  • Build scalable, reusable workflows using Dataverse and Power Platform
  • Partner with business teams to streamline and automate critical processes

API & Integration (Critical)
  • Design and implement RESTful APIs and system integrations
  • Connect internal systems and third-party platforms securely and reliably
  • Perform data mapping and transformation across systems

Azure & DevOps
  • Build and support solutions in Microsoft Azure
  • Create and maintain CI/CD pipelines and automated deployments
  • Use Infrastructure as Code to provision and manage environments
  • Ensure solutions are secure, scalable, and observable

What You Bring
  • Strong experience building Power Apps (model-driven) and Power Automate workflows
  • Proven ability to design and deliver API integrations (REST/JSON)
  • Hands-on experience with Microsoft Azure
  • Experience with CI/CD pipelines and DevOps practices
  • Ability to simplify complex processes into efficient automated solutions

Nice to Have
  • Experience in regulated industries (banking, finance)
  • Familiarity with ServiceNow or RPA tools
  • Exposure to SharePoint

What We Value
  • Practical experience delivering real automation outcomes, not certifications
  • A focus on standardization, scalability, and simplicity
  • Ability to drive change and modernize legacy processes

Qualifications, Competencies and Skills
What You Need for this Position
  • Minimum of five years software development experience required
  • Hands-on software trouble-shooting experience.
  • Knowledge of applicable data privacy practices and laws.
  • Experience working both independently and in a team-oriented, collaborative environment

Compensation Disclosure
The range for this role takes into account many factors that First Bank considers when making hiring decisions, including but not limited to prior experience, skill set, training, and other internal business and organizational factors. First Bank generally does not hire at or near the top of the stated range. The range is driven by the geographic location of the anticipated hiring location; however, the specific range may vary depending on the geographic location for remote positions. Compensation decisions depend on the specific facts and circumstances of each hiring instance. A reasonable estimate of the current pay range is $110,000 - $130,000 per year.
