Senior Software Engineer

You will lead our GraphQL API strategy and delivery

Your primary focus will be the new application suite

Required Skills and Selection Criteria:

• Minimum of 8+ years experience in technical engineering roles, with

  significant, demonstrable experience in designing, developing, and architecting complex, cloud-native applications.

• Deep understanding of cloud-first strategies and design principles, specifically with

  hands-on experience building applications on Google Cloud Platform (GCP) or one of the other major cloud platforms.

• 3+ years of hands-on, production experience

  designing and delivering GraphQL APIs at scale

  (schema-first/SDL), including resolver design, schema evolution, and consumer alignment.
• Practical experience with GraphQL in Java ecosystems (e.g., Spring for GraphQL, graphql-java, or Netflix DGS). Experience with federation patterns (e.g., Apollo Federation) is highly desirable.
• Strong application architecture knowledge designing solutions with API Gateways (e.g., Apigee) and GraphQL-first APIs (with complementary REST where appropriate). Solid experience designing RESTful APIs and understanding when REST vs GraphQL is the right fit.
• Deep familiarity with GraphQL performance and security: DataLoader, caching and persisted queries, query cost/depth/complexity limits, and field-level authorization with OAuth2/JWT.
• Experience operating GraphQL on GCP (Cloud Run/Functions, Apigee GraphQL proxy or Apollo Gateway), with CI/CD integration and production-grade observability/tracing.
• Proven hands-on expertise working with applications using Java frameworks (especially Spring Boot/Spring MVC/Spring Batch).
• Strong application architecture knowledge designing with GCP serverless technologies (e.g., Cloud Run, Cloud Functions, App Engine).
• Exceptional technical leadership, communication, and interpersonal skills. Proven ability to clearly articulate complex technical ideas to both technical and non-technical audiences (developers, product owners, business stakeholders, management). Strong problem-solving skills.

Nice to Have

• Google Professional Cloud Architect certification
• Master s degree in computer science / engineering, Data science or related field
• Experience in Banking, Finance, or Automotive Finance domains.
• Commercial development experience using front-end frameworks like React or Angular (for understanding full-stack implications) and consuming GraphQL APIs from these clients.
• Ability to work on multiple related components within the application suite in a fast-paced & dynamic environment.
• Experience with No-SQL and BigQuery databases is a plus.
• Experience with GraphQL schema registry and contract tooling (e.g., Apollo Studio, GraphQL Inspector) and integrating contract checks into CI/CD.
• Familiarity with frontend GraphQL clients (Apollo Client, Relay) and pagination patterns (e.g., Relay-style connections) to optimize consumer experience.

Role & Responsibilities:

• Lead the technical design and architecture

  within the dedicated squad for the Vehicle Configuration Service, Residual Data, and Marketing Program applications.

• Own the end-to-end GraphQL architecture

  for these services, including schema (SDL) design, query/mutation/subscription definitions, resolver design, and schema evolution.
• Establish schema

  governance and versioning strategies

  (naming conventions, deprecation policies, schema registry) and drive consumer-aligned API contracts with European stakeholders.
• Drive

  GraphQL performance, reliability, and security

  : DataLoader-based batching, caching strategies, avoiding N+1, persisted queries, query cost/depth/complexity limits, and robust observability/tracing.
• Collaborate closely with the Product Lead, Business Analysts, Architects, and European Stakeholders to

  understand requirements and translate them into robust, scalable, and efficient application-level technical solutions

  on GCP.
• Develop and maintain key application architecture documentation, including component designs, sequence diagrams, API specifications (GraphQL SDL and, where used, REST/OpenAPI), and technical design documents, ensuring clarity and alignment with best practices.
• Provide

  hands-on technical leadership and guidance to the development team

  (senior and junior engineers), mentoring them on best practices (including schema-first development, contract testing, and non-breaking evolution), performing code reviews for critical components, and overseeing the implementation of architectural designs.
• Perform

  technical feasibility studies, evaluate technology choices, frameworks, and patterns

  specifically for the application, ensuring they meet functional and non-functional requirements.
• Actively

  participate in hands-on development for proofs-of-concept, complex features, or critical troubleshooting

  to drive progress and resolve technical challenges.
• Champion technical excellence, code quality, and sound engineering practices within the team.
