Calling all innovators – find your future at Fiserv.

We’re Fiserv, a global leader in Fintech and payments, and we move money and information in a way that moves the world. We connect financial institutions, corporations, merchants, and consumers to one another millions of times a day – quickly, reliably, and securely. Any time you swipe your credit card, pay through a mobile app, or withdraw money from the bank, we’re involved. If you want to make an impact on a global scale, come make a difference at Fiserv.

Job Title

Principal Engineer

About your role:

At Fiserv, we are modernising a high-volume global payment processing platform — moving from a monolithic, batch-driven architecture to an event-driven microservices platform on AWS. This is a ground-up build: Confluent Cloud for event streaming, Aurora PostgreSQL for persistence, Kubernetes for compute, and a modern Java/Kotlin stack throughout.

As a Principal Engineer, you will drive technical delivery strategy across the programme — shaping the architecture patterns teams build on, driving the engineering practices that ensure quality at pace, and making every team around you faster and more effective. You will have influence across both engineering teams and the architecture community, coaching and challenging in equal measure.

You believe AI fundamentally changes how software is built and delivered, and you will drive its adoption as a core part of how teams work — from architecture and design through to code, testing, and delivery.

This is hands-on and outward-facing. You will lead through code, architectural direction, and constructive challenge — ensuring we are building the right things in the right way, and getting to production incrementally rather than in big-bang releases.

What you’ll do:

Own the technical delivery strategy — how we decompose, sequence, and integrate work so that teams deliver end-to-end value early and iterate from there.
Shape cross-cutting architecture patterns — resilience, event-driven integration, idempotency, observability — and ensure they are adopted consistently across services.
Drive architecture decisions toward delivery — challenging over-engineering, unblocking teams when decisions stall, and ensuring designs are practically deliverable.
Establish engineering practices that scale: test-driven development, contract testing, continuous integration, trunk-based development, and vertical slicing.
Coach and raise the bar across engineers and architects — through pairing, design review, code review, and hands-on demonstration of what good looks like.
Apply domain-driven design practically — bounded context integration, aggregates in code, anti-corruption layers — bridging strategy and implementation.
Define testing strategy for an event-driven microservices architecture — unit, integration, contract, and end-to-end, with clear guidance on where each adds value.
Ensure teams are self-sufficient faster — through reusable patterns, service templates, and clear architectural guardrails that accelerate rather than constrain.

Experience you’ll need to have:

Significant experience as a senior/principal engineer or technical lead delivering distributed systems in production.
Deep hands-on experience with modern Java or Kotlin, Spring Boot, and microservices architectures.
A track record of shaping technical strategy and architecture direction across multiple teams — not just delivering within one.
Strong experience with event-driven architectures — Kafka, event sourcing patterns, eventual consistency, and integration patterns.
Practical application of domain-driven design — both strategic (bounded contexts, context mapping) and tactical (aggregates, domain events, repositories).
Experience designing for resilience in distributed systems — circuit breakers, retries, timeouts, bulkheads, graceful degradation.
Proven ability to coach and influence engineers and architects, shifting culture toward pragmatic engineering excellence.
A conviction that AI-assisted engineering is transformative, with experience applying AI tools to accelerate development, testing, or delivery workflows.
Experience with iterative delivery — vertical slicing, walking skeletons, integration-first approaches.

Experience that would be great to have:

Familiarity with payments, financial services, or high-volume transactional domains is a plus but not essential.
Exposure to Confluent Cloud, AWS, Kubernetes, GitLab CI, or observability tooling (Dynatrace, distributed tracing) is beneficial.
