As a Full Stack Software Engineer II , you will work end-to-end across front-end and back-end systems to ship features that directly impact our customers and partners.

Role Overview

You will:

• Design, build, and operate end-to-end product features across the stack (front-end, back-end, data & integration).
• Work in a cross-functional team (product, design, data, other engineers) to solve real customer problems.
• Take ownership from design and implementation to production, monitoring and iteration.
• Contribute to engineering quality, reliability, and best practices within your team.
• Rapidly developing next-generation scalable, flexible, and high-performance services for the SS&F Department.
• Design, Develop and Maintain High Critical Services serving

Key Responsibilities

• Design & build end-to-end features across web front-ends and back-end services.
• Implement and evolve APIs and microservices (REST/GraphQL/event-driven) that are secure, scalable, and observable.
• Develop user interfaces using modern JavaScript/TypeScript, HTML/CSS and a component-based framework (e.g. React or equivalent).
• Strong experience designing and implementing backend services in Java (or similar JVM languages), including APIs, business logic and integrations.
• Work with relational databases (e.g. MySQL) and caching solutions to model, store and retrieve data efficiently.
• Write high-quality, testable code with unit, integration and end-to-end tests as appropriate.
• Use CI/CD pipelines to ship changes frequently and safely.
• Monitor services in production (logs, metrics, traces, alerts) and participate in on-call / incident response where applicable.
• Collaborate closely with product, design and data to refine problems, define solutions and run experiments (A/B tests).
• Contribute to technical design discussions, code reviews, and knowledge sharing.
• Champion security, privacy, performance and reliability in your solutions.
• Mentor junior engineers informally and help raise the engineering bar in the team.

Required Qualifications

• 5-8 years of professional software engineering experience, including production systems.
• Have a strong drive to build high quality systems and improve the quality of existing systems
• Strong skills in back-end language (Java, Spring Boot / Dropwizard) and one modern front-end framework (e.g. React).
• Experience building and consuming HTTP APIs / microservices.
• Solid understanding of data structures, algorithms, and object-oriented design.
• Hands-on experience with relational databases (MySQL or equivalent) and writing efficient SQL.
• Experience with automated testing (unit, integration; familiarity with test pyramids and quality gates).
• Experience using CI/CD tools and version control (Git).
• Comfort working in agile, cross-functional teams and collaborating with non-engineering stakeholders.
• Strong communication skills, with the ability to explain trade-offs and make pragmatic decisions.
• Mindset of ownership, learning and continuous improvement.
• Experience using modern AI tooling (e.g. Claude, GitHub Copilot, Windsurf or similar) to accelerate design, coding, testing and documentation, while maintaining high engineering standards.
• Experience operating high-volume, low-latency services in production, including performance tuning, capacity planning and incident handling.
• Hands-on experience with AWS cloud services (e.g. EC2/EKS, S3, RDS, networking and monitoring) for deploying and operating backend workloads.

Nice-to-Have

• Experience with high-traffic, distributed systems and performance tuning.
• Exposure to Kubernetes / container orchestration and cloud environments (e.g. AWS).
• Experience with message queues / streaming (e.g. Kafka) and event-driven architectures.
• Familiarity with A/B testing and experimentation platforms.
• Front-end experience in design systems / component libraries and accessibility best practices.
• Previous experience in e-commerce, travel, payments, or fraud/risk domains.
