Senior Java Engineer

As a Senior Java Engineer at ING, you are a senior technical leader and a hands-on expert who raises the engineering bar across multiple squads.

You design and evolve complex, scalable systems, lead critical initiatives end-to-end, and mentor engineers across chapters. You are adept at simplifying complexity, shaping technical strategy, and ensuring high standards in security, reliability, performance, and developer experience. You collaborate closely with Product Owners, Chapter Leads, and Architects to deliver resilient customer and platform outcomes—aligned with ING’s engineering standards and regulatory expectations.

Key Responsibilities

Technical Leadership & Architecture

• Own the architecture and technical direction of one or more business-critical domains, ensuring scalability, resilience, and security-by-design.
• Design and evolve APIs, services, data models, event-driven architectures, and integrations that meet strict availability and latency objectives (e.g., 99.9%+ where applicable).
• Lead threat modeling, capacity planning, performance engineering, and observability (SLOs, SLIs, error budgets).
• Run deep design reviews and RFCs, drive decisions with data, and ensure decisions are documented and discoverable.

Delivery & Operational Excellence

• Lead the end-to-end delivery of complex initiatives: discovery, design, implementation, testing, rollout, and post-incident learning.
• Drive reliability engineering practices (e.g., chaos experiments, failure injection, game days, postmortems with clear remediations).

Coding & Quality

• Write clean, secure, well-tested code; contribute to high‑impact components and reference implementations.
• Raise quality via code reviews, pairing/mobbing, test strategy, and non-functional requirements as first-class citizens.
• Improve developer experience (tooling, templates, libraries, golden paths), reducing cycle time and toil.

Security, Risk & Compliance

• Embed privacy, data protection, regulatory controls, and auditability in system design and pipelines.
• Partner with Control, Risk, and Security teams to meet bank-grade compliance (e.g., identity, secrets management, encryption-in-transit/at-rest, logging, traceability, segregation of duties).

Qualifications

Experience & Seniority

• 8+ years of professional software engineering experience, with a strong track record delivering and operating complex, distributed systems in production environments.
• Proven experience acting as a senior technical leader across multiple squads or domains, influencing architecture and engineering standards beyond a single team.
• Demonstrated ownership of business‑critical systems with high availability, resilience, and regulatory requirements (e.g., banking, fintech, or similarly regulated environments).

Technical Expertise

• Strong hands-on expertise in modern backend and/or full‑stack development (e.g., Java, Spring Boot, cloud‑native services, APIs).
• Deep understanding of:
  • Distributed systems design (scalability, consistency, fault tolerance)
  • Event-driven architectures, messaging, and integration patterns
  • API design (REST, async/event APIs), data modeling, and service decomposition
• Proven experience with reliability engineering concepts such as SLOs, SLIs, error budgets, capacity planning, and performance engineering.
• Strong experience with observability tooling (logging, metrics, tracing) and production support at scale.

Security, Risk & Compliance

• Strong understanding of security‑by‑design principles and embedding controls into system architecture and delivery pipelines.
• Practical experience with:
  • Identity and access management
  • Secrets management
  • Encryption in transit and at rest
  • Auditing, logging, and traceability
