About the Role

We are seeking a highly skilled and versatile Senior Manager, Software Development to join our Enterprise Digital Solutions team. This is an individual contributor role at the Senior Manager level, with no direct people management responsibilities. 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.

Key Responsibilities

Full Stack Development

• Design, build, and maintain scalable front-end and back-end applications using modern frameworks and best practices.
• Develop responsive, user-centric UI components and integrate them with cloud-hosted APIs and microservices.
• Own end-to-end feature development from requirements through deployment and post-release monitoring.

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.
• Familiarity with big data technologies, data pipelines, or analytics platforms.
• Knowledge of security best practices for cloud applications (IAM, secrets management, OWASP).
