Overview

We are looking for a senior software engineer with 5-10+ years of experience, with skills in modern Java, microservices, event-driven architectures, and cloud-native environments, who has already worked in production on complex and scalable systems. You will work in the Group Technology area of Intesa Sanpaolo as a senior individual contributor, solving complex technical problems independently, contributing to architectural decisions, bringing end-to-end solutions to production, and acting as a technical reference and mentor for more junior colleagues.

What your activities will be

  • Design, implement, test, and operate microservices on Quarkus and JVM/GRAALVM, exposing REST/GRPC or event-based interfaces.
  • Design event-driven flows on Kafka: topic topology, schema evolution (Avro/Protobuf), exactly-once semantics, retries, and dead-letter strategies.
  • Model and evolve persistence on MongoDB (document modeling, indexing, aggregation) and AlloyDB / PostgreSQL (relational modeling, performance tuning).
  • Package services as containers, deploy and optimize them on Kubernetes / GKE, with adequate observability (logs, metrics, traces).
  • Contribute to CI/CD pipelines, infrastructure-as-code (Terraform), and shared libraries / golden paths used by the entire team.
  • Review code written by junior colleagues; perform pair programming on non-trivial tasks; conduct brown-bag sessions and technical talks.
  • Investigate end-to-end production issues, including non-obvious ones that cross service and team boundaries.

Who we are looking for

If you have the following characteristics, we are waiting for you:

  • At least 5 years of hands-on software engineering experience in production environments and as a backend Software Engineer for distributed systems.
  • Deep expertise in modern Java (17/21/25), including concurrency, JVM performance, memory model, and testing.
  • Production experience with a modern microservices framework - Quarkus (preferred), Spring Boot, Micronaut, or Helidon. Candidates without Quarkus experience are welcome if the rest of their profile is solid and they demonstrate a willingness to retrain.
  • Hands-on Kafka in production: producer/consumer semantics, partitioning strategy, consumer groups, schema registry, idempotency, DLQ. Experience with Confluent Platform / Confluent Cloud is a plus.
  • Experience with a document database (MongoDB strongly preferred) and a PostgreSQL-compatible relational database (AlloyDB, Cloud SQL, Aurora, pure PostgreSQL). Ability to choose the right one and design schemas that scale.
  • Solid cloud-native fundamentals: Docker, Kubernetes, Helm, at least one hyperscaler in production (GCP strongly preferred; AWS or Azure acceptable with willingness to transfer).
  • Distributed systems culture: CAP, eventual consistency, idempotency, retry and back-off, outbox / transactional messaging, saga / choreography, CQRS.
  • CI/CD and DevEx: Git, pipeline design, automated testing strategies (unit, integration, contract, end-to-end), infrastructure-as-code (Terraform).
  • Observability: structured logging, metrics, distributed tracing (OpenTelemetry), ability to debug in production.

Preferred qualifications include the following knowledge:

  • Production experience with Quarkus, particularly native compilation / GraalVM.
  • Google Cloud Platform in production (GKE, AlloyDB, Pub/Sub, Cloud Run, IAM).
  • Confluent Platform / Confluent Cloud (schema registry, ksqlDB, Kafka Streams / Flink).
  • Domain-Driven Design applied to real-world systems (bounded context, aggregates, ubiquitous language).
  • Experience at scale: microservice ecosystems with dozens of services, or throughput in the order of thousands of events per second.
  • Experience in a regulated sector (financial services, insurance, telco, healthcare, utilities) - not just banking.
  • Security-aware development: OAuth 2.0 / OIDC, secret management, threat modelling, secure SDLC.
  • Previous experience in banking or payments (core banking, ledger, pricing, MDM, account servicing).
  • Contributions to open-source projects, technical blogs, speaking at conferences.
  • Experience in migrating workloads from legacy / mainframe systems.
  • Familiarity with the regulatory context relevant to core banking (DORA, PSD2, GDPR) from an engineering perspective.

What we offer you

  • Gross annual salary starting from €50.000

  • The Group provides a variable component of remuneration as regulated by the Remuneration Policies available on the Group website

  • Complementary elements regulated by the National Collective Labor Agreement for Credit and second-level company agreements

  • Professional development initiatives to support the growth of our people

  • Wide range of training offered through the Corporate Academy dedicated to the continuous development of professional, managerial, and transversal skills at all levels

  • Possibility to join flexible work arrangements and the 4x9 short week

  • Modern and integrated corporate welfare system ( link)

  • Health coverage and supplementary pension starting from hiring

  • Advantages on Group banking products and services
