About the Role
We are seeking a highly skilled and versatile Senior Manager, Software Development to join our Enterprise Digital Solutions team. In this role, you will design, develop, and maintain applications across the full technology stack — from intuitive front-end interfaces to robust back-end services — while leveraging existing integration platforms and tools to enable seamless data flow across the enterprise. You will play a key role in building and maintaining CI/CD pipelines, enforcing code security practices, managing the code repository, and driving application lifecycle management within an Agile environment.
Work arrangement:
This role offers flexibility to work away from the office for 20%–40% of a typical schedule. Employees may use this work schedule in increments of single days or multiple consecutive days, provided it does not exceed 40% within a 60-day period, and is approved by the hiring manager.

Integration & Data Enablement
- Leverage and extend existing enterprise integration platforms (e.g., Informatica IICS, or equivalent) to enable data flow across systems.
- Design and implement APIs, event-driven integrations, and data pipelines to connect applications and enable real-time and batch data enablement across the enterprise.
- Collaborate with data engineering and architecture teams to ensure integration patterns align with data governance and quality standards.
CI/CD & DevOps
- Design, implement, and maintain CI/CD pipelines using GitHub Actions, GitLab CI/CD, AWS CodePipeline, or similar tools.
- Automate build, test, and deployment workflows to accelerate delivery and improve code quality.
- Enforce infrastructure-as-code (IaC) practices using tools such as Terraform, CloudFormation, or CDK.
Application Lifecycle Management
- Manage the complete application lifecycle including version control, environment management, and release planning.
- Monitor application health, performance, and security; proactively identify and resolve issues.
- Maintain technical documentation, runbooks, and architecture decision records.
Code Security & Repository Management
- Implement and enforce code security best practices including static analysis (SAST), dependency scanning, and secrets detection within the development workflow.
- Own and manage the code repository (GitHub / GitLab) including branching strategy, access controls, merge/pull request workflows, and repository hygiene across all application projects.
- Ensure code quality gates, vulnerability remediation, and compliance checks are embedded in the CI/CD pipeline and enforced prior to release.
Agile & Collaboration
- Participate actively in Agile ceremonies — sprint planning, stand-ups, retrospectives, and backlog grooming.
- Collaborate cross-functionally with enterprise architects, product managers, UX designers, QA, Information and security and DevOps teams.
- Mentor junior engineers and contribute to code reviews with constructive, standards-driven feedback.
Required Qualifications
- 8+ years of professional experience in full stack software development, with demonstrated experience in application integration and data enablement.
- Strong proficiency in front-end technologies (React, Angular, or Vue.js) and back-end frameworks (Node.js, Python, Java, or similar).
- Hands-on experience with enterprise integration platforms or middleware (e.g., Informatica IICS, or equivalent) and RESTful/event-driven integration patterns.
- Demonstrated expertise designing and managing CI/CD pipelines with GitHub Actions, GitLab CI/CD, or comparable tools.
- Solid understanding of RESTful APIs, microservices architecture, and containerization (Docker, Kubernetes).
- Experience with application lifecycle management tools and version control workflows using GitHub or GitLab (branching strategies, protected branches, merge/pull requests).
- Working knowledge of code security tooling (SAST, DAST, dependency scanning) and secure SDLC practices, with experience embedding security checks into CI/CD workflows.
- Strong analytical and problem-solving skills with a proactive, ownership mindset.
Preferred Qualifications
- AWS Certified Developer, AWS Solutions Architect, or equivalent cloud certification (Azure, GCP).
- Certification or deep experience with an enterprise integration platform (Informatica IICS, or equivalent).
- Experience designing or consuming data pipelines, ETL/ELT processes, or working with data enablement platforms such as Informatica, and Databricks.
