Role Overview:

As a Senior Staff Software Engineer, you play a key role in technical execution and strategic architecture within your domain. Above all else, you aim to satisfy customer and business needs by delivering solutions that advance ABC's mission and goals. You lead the design, development, and implementation of sophisticated, modern software solutions while ensuring alignment with business objectives, system architecture, and customer outcomes.

Beyond implementation, you are also accountable for domain-level architecture, ensuring that services, APIs, and system components are scalable, modular, performant, and maintainable. You regularly collaborate with Enterprise/Solution Architects, Product Owners, and Engineering Managers to define technical boundaries, enforce best practices, and drive long-term technical strategy.

You will also guide and mentor engineers, fostering a culture of technical excellence, innovation, and continuous improvement. You play a crucial role in cross-functional collaboration, stakeholder engagement, and risk management, ensuring that technical decisions align with both business goals and engineering best practices.

Key Responsibilities:

• Shared Technical Leadership & Strategy

• Set a clear technical vision for the domain, ensuring alignment with strategy, long-term business goals and platform architecture.

• Lead the design, development, and deployment of scalable, high-performance backend and frontend solutions.

• Ensure that coding standards, architectural principles, and system design best practices are consistently followed and collaboratively advanced.

• Collaborate with Technical Architects and Engineering Managers to ensure engineering scalability, maintainability, performance, and security.

• API-Led Integration Development: Design, build, and implement API-driven integrations using modern integration platforms and methodologies.

• Leverage REST APIs, event-driven APIs, batch jobs, and API-led approaches to deliver efficient and scalable solutions.

• Ensure seamless data flow across systems by developing and maintaining robust integration solutions that meet the needs of internal and external stakeholders.

• Create and maintain comprehensive documentation for system and interface designs, ensuring integrations are easily understood, maintained, and updated over time.

• Software Quality & Testability

• Ensure testing is built alongside solutions, embedding unit, integration, and automated UI testing to improve reliability and maintainability.

• Advocate for testability in design and implementation, encouraging practices such as Test-Driven Development (TDD), Behavior-Driven Development (BDD), and Acceptance-Test-Driven Development (ATDD) where appropriate.

• Work with QA, automation engineers, and engineers to define effective, scalable testing strategies that support rapid and safe deployment.

• Promote clean coding practices, small batch changes, effective and efficient code reviews, and continuous integration to ensure a high standard of software quality.

• Domain Architecture & Design

• Define and maintain domain architecture, in coordination with their respective value stream, ensuring alignment with system-wide principles and business and customer needs.

• Work closely with enterprise and platform architects to ensure domain models, service boundaries, and technical solutions are well-structured and scalable.

• Ensure that technical solutions within the domain align with performance, resilience, and future scalability requirements.

• Work Breakdown

• Break down high-level designs or feature descriptions into actionable technical tasks with clear acceptance criteria. Collaborate with team members across disciplines, including web/mobile developers, business analysts, testers, DevOps, and product managers, to align on implementation plans.

• Innovation & Continuous Improvement

• Evaluate and adopt emerging technologies -in alignment with strategy- that improve software quality, performance, and efficiency.

• Promote a culture of continuous learning, driving improvements in engineering processes, automation, and tooling.
