About The Role
DATAE is building an operations console for large, regulated banks: a single window where infrastructure operations teams can see and act on events, job status and incidents from many mainframe and enterprise tools, without switching between six or more products.
We're looking for a senior backend engineer to lead the integration and security backbone of the platform. You'll design how the console connects to each tool, processes events in real time, and enforces enterprise-grade security: certificates, SSO, RBAC and audit. You'll work closely with our mainframe specialists, a second backend engineer focused on integration and AI, and a frontend engineer.
What You'll Do
Design and build the backend architecture, including a pluggable connector layer for each integrated tool.
Build real-time event processing: ingestion, normalisation, deduplication, correlation and an event lifecycle (acknowledge, assign, escalate, resolve).
Own security end to end: certificate management and mTLS, SSO integration, RBAC and fine-grained permissions, approval workflows for high-risk actions, and tamper-evident audit logging.
Integrate with enterprise systems such as ServiceNow, event management platforms and collaboration tools.
Deliver real-time updates to the frontend.
Design the platform to run on a public cloud or on-premises, depending on each bank's requirements.
Work with bank security and infrastructure teams through security reviews, penetration testing and audit requirements.
Set engineering standards for code quality, testing, CI/CD and documentation, and mentor the wider team.
What We're Looking For
7+ years of backend engineering, with strong Java/Spring Boot. Working knowledge of Python is a plus.
Proven experience designing integrations across many third-party systems via REST APIs, with resilience patterns (retries, circuit breakers, idempotency, rate limiting).
Hands-on Kafka and event-driven architecture.
Certificate management: X.509, PKI, mTLS, keystores/truststores, automated rotation and expiry monitoring (e.g. HashiCorp Vault, Venafi, cert-manager).
SSO: OAuth 2.0, OpenID Connect and SAML 2.0 with enterprise identity providers such as Entra ID, Okta or Ping; JWT handling and service identities.
Authorisation: RBAC design, mapping directory groups to roles, least privilege, approval workflows.
Security engineering: OWASP Top 10, secrets management, encryption in transit and at rest, audit logging to a SIEM, threat modelling, secure SDLC (SAST, DAST, dependency scanning).
PostgreSQL, plus Elasticsearch/OpenSearch and Redis.
Cloud-native, portable design: Docker and Kubernetes or Red Hat OpenShift, able to run in public cloud or on-premises without unnecessary lock-in.
CI/CD, infrastructure as code, and observability (OpenTelemetry, Prometheus).
Strong plus
Experience in banking or financial services, working within controls such as SOX, PCI DSS, NIST 800-53 or SOC 2, and with FIPS-validated cryptography.
Hands-on experience with at least one major cloud (Azure, AWS or GCP), ideally Azure: networking (VNets/VPCs, private endpoints), identity (managed identities, IAM), key and certificate management (Azure Key Vault, AWS KMS/ACM) and Terraform.
Hybrid connectivity between cloud and on-premises environments, including secure network paths to data centres.
Cloud security and compliance controls in regulated industries (e.g. CIS benchmarks, cloud security posture management).
Integration with ServiceNow and event management tools (Netcool, BMC, PagerDuty or similar).
Real-time delivery via WebSockets or server-sent events.
High-availability and DR design.
Nice to have
Exposure to mainframe integration: Zowe API Mediation Layer, z/OSMF REST APIs, z/OS Connect, mainframe data via Kafka, or RACF/PassTicket authentication.
Experience building a product used by multiple clients.
You don't need every item on this list, but strong integration engineering and hands-on security (certificates, SSO, RBAC) are essential.
