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 autonomously, contributing to architectural choices, delivering end-to-end solutions into production, and acting as a technical reference and mentor for more junior colleagues.

What you will do

  • 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, retry, dead-letter strategies.
  • Model and evolve persistence on MongoDB (document modelling, indexing, aggregation) and AlloyDB / PostgreSQL (relational modelling, performance tuning).
  • Package services as containers, deploy and optimise 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; do pair programming on non-trivial tasks; run brown-bag sessions and technical talks.
  • Investigate production issues end-to-end, 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 of distributed systems.
  • Deep expertise in modern Java (17/21/25), including concurrency, JVM performance, the memory model and testing.
  • Production experience with a modern microservices framework - Quarkus (preferred), Spring Boot, Micronaut or Helidon. Candidates without Quarkus are welcome if the rest of the profile is solid and they show willingness to upskill.
  • Hands-on production Kafka: 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 to design schemas that scale.
  • Solid cloud-native fundamentals: Docker, Kubernetes, Helm, and at least one hyperscaler in production (GCP strongly preferred; AWS or Azure acceptable with willingness to transfer).
  • Culture of distributed systems: 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), production debugging skills.

The following are considered a preferential advantage:

  • 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 systems (bounded contexts, aggregates, ubiquitous language).
  • Experience at scale: microservice ecosystems with dozens of services, or throughput on the order of thousands of events per second.
  • Experience in a regulated sector (financial services, insurance, telco, healthcare, utilities) - not only banking.
  • Security-aware development: OAuth 2.0 / OIDC, secrets 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, conference talks.
  • Experience migrating workloads from legacy systems / mainframes.
  • Familiarity with the regulatory context relevant to core banking (DORA, PSD2, GDPR) from an engineering perspective.
  • Significant professional or study experience in international contexts.

What we offer

  • Gross annual salary starting from 50.000 €

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

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

  • Professional development initiatives supporting the growth of our people

  • Possibility to opt for flexible work and the 4x9 compressed week

  • Modern and integrated corporate welfare system ( link)

  • Health coverage and supplementary pension from the date of hiring

  • Advantages on the Group's banking products and services
