Job description

We are seeking a highly technical, forward-thinking Technical Lead to drive the end-to-end design, development, and integration of our core API ecosystem. In this role, you will balance hands-on backend engineering with strategic technical leadership—guiding a team of systems analysts and developers to deliver scalable, high-performance solutions.

Drawing from top-tier banking engineering standards, you will be responsible for alignment of the technical direction, evolving engineering best practices, and ensuring our platforms deliver exceptional reliability, observability, and business value.

Team Leadership & Delivery Alignment

• Engineering Mentorship: Lead, mentor, and strengthen the development team; foster a collaborative environment and cultivate a high bar for engineering craftsmanship.
• Cross-Functional Collaboration: Partner closely with Product Owners to scope, review, and refine user stories, and collaborate with Solutions Architects to map out robust technical solutions.
• Roadmap & Project Delivery: Plan, drive, and execute 2 to 5 parallel project implementations, ensuring milestones align seamlessly with the broader product roadmap.

Architecture, Integration & Cloud Evolution

• API & Microservices Architecture: Design and review highly secure, scalable, and resilient RESTful APIs and distributed microservices platforms.
• Financial & Systems Integration: Lead complex third-party and backend system integrations, with an emphasis on optimized routing and secure financial message transformation.
• Cloud & Infrastructure Advocacy: Continuous evolution of cloud infrastructure, making it easier for engineers to utilize cloud platforms efficiently while maintaining code quality and system performance.

Git Workflow & GitOps Process Engineering

• Process Standards Definition: Define, standardize, and govern the team's version control branching strategies and code promotion pathways.
• Commit Strategy & Hygene: Enforce strict rules around atomic commits, structured conventional commit messages, and local pre-commit hooks (e.g., linting, secret scanning, formatting).
• Merge Request (MR / PR) Governance: Establish rigorous merge request policies including mandatory peer code reviews, automated security/vulnerability gating, architectural alignment checks, and successful integration test runs before approval.
• Post-Merge Activities & Automation: Oversee post-merge triggers, ensuring successful automated deployment to lower environments (Staging/UAT), managing artifact versioning/tagging, executing post-deployment sanity/smoke tests, and tracking deployment observability metrics.

Testing, Observability, & Incident Management

• Development and Production Escalation: Act as the ultimate technical point of escalation to rapidly diagnose, troubleshoot, and resolve critical production issues.
• Quality Assurance & Sanity Testing: Drive the execution of thorough deployment sanity testing across environments to validate critical workflows and integration points before production releases.
• System Reliability: Focus deeply on system reliability and observability, ensuring proactive health tracking and automated error management across environments.

Core Development & Frameworks

• Experience: Minimum 5 to 8 years of hands-on experience in backend development using C#.NET Framework and .NET Core/.NET 6+.
• Banking Domain Tech (Plus): Familiarity or proficiency with modern banking ecosystem architectures (e.g., Java/Spring Boot microservices or core banking platforms) is a major advantage.
• Integration Standards: Deep understanding of data serialization, API management platforms, and financial messaging formats (JSON, XML, SOAP).
• Processes: Solid experience developing automated background processes, batch jobs, and console applications.

Testing & Code Quality

• Unit Testing: Proven expertise in writing comprehensive unit tests and utilizing mocking frameworks to maintain high code coverage and ensure business logic accuracy.
• Sanity & Regression Testing: Experience designing and executing rapid sanity checks and API test suites (e.g., via Postman, SoapUI, or automated scripts) to verify core API health post-deployment.

Database & Data Management

• Strong proficiency in relational database management systems, specifically PostgreSQL and Microsoft SQL Server (MSSQL).
• Advanced capability in writing optimized SQL queries, complex stored procedures, and managing evolving data schemas.

DevOps, Cloud & Infrastructure

• Containerization & Orchestration: Hands-on experience with containerization using Docker and production orchestration platforms like Kubernetes (K8s) or Red Hat OpenShift.
• Cloud Experience: Prior experience building and deploying scalable solutions on major cloud infrastructure, preferably AWS, GCP, or Azure.
• CI/CD & Agile: Strong understanding of automation through modern CI/CD practices (Git, automated deployment pipelines) paired with Agile methodologies using tools like Jira.

Accountability & Adaptability

• Accountability & Adaptability: A strong problem-solving mindset with the resilience to thrive under pressure and adapt to moving project scopes.
• Strategic Communication: Excellent verbal and written communication skills to translate dense technical architecture into actionable, dependency-free tasks for developers.
• Critical Thinking & Quality Focus: A natural inclination toward establishing engineering standards, ensuring rigorous unit test code coverage, and maintaining thorough system documentation.

Benefits

• Government Mandated Benefits (SSS, Pag-Ibig, Philheath, and 13th month)
• Health Insurance
• Standard Leave (Emergency, Sick, and Vacation)
