Senior Backend Engineer — 1Secure Platform

Position Overview

We are building a cloud-native SaaS platform composed of Java and Spring Boot services deployed to Kubernetes. The platform uses REST and gRPC APIs, reactive and event-driven communication patterns, and a combination of relational, document, caching, and search technologies. The platform architecture and engineering standards are established; engineers will extend existing services and build new capabilities within those guardrails.

Candidates must be able to navigate an unfamiliar codebase, trace request, event, and data flows across services, and own changes through implementation, automated testing, deployment, observability, and production support.
We value practical engineering judgment over a checklist of technologies. Candidates should be able to explain design choices, make sensible trade-offs, and build services that are secure, observable, testable, and supportable in production.

This is a hybrid role with visits to our Kraków office.

Key Responsibilities

• Build maintainable backend services and APIs using modern Java, Spring Boot, and appropriate Spring modules, following the platform's defined architecture and standards.
• Read and understand existing code across services to grasp feature sets, data flows, and integration points, and build on them effectively.
• Develop reactive, non-blocking services with Spring WebFlux and Project Reactor, with practical judgment about when reactive programming is - and is not - the right choice.
• Implement well-designed REST APIs and, where appropriate, gRPC services, with clear contracts, validation, versioning, error handling, and backward compatibility.
• Build event-driven integrations using Kafka and/or RabbitMQ, applying sound practices for message delivery, idempotency, retries, ordering, and dead-letter handling.
• Model and access data in relational databases (PostgreSQL/MySQL) and NoSQL databases, apply caching effectively with Redis, and use Elasticsearch/OpenSearch for indexing and search workloads.
• Package and deploy services to Kubernetes end-to-end: authoring Helm charts, managing Kubernetes configuration (ConfigMaps, Secrets (Hashicorp Vault), health probes, resource requests/limits, HPA), and executing safe rolling deployments.
• Write automated tests, participate in design and code reviews, troubleshoot production issues, and continually improve service reliability and performance.
• Collaborate with product, architecture, security, DevOps/SRE, and other engineering teams throughout the software delivery lifecycle.

Qualifications

• Strong Java development skills: object-oriented design, collections, concurrency, asynchronous processing, and JVM fundamentals.
• Production experience with Spring Boot; practical knowledge of Spring WebFlux/Project Reactor and reactive programming principles.
• Demonstrated ability to ramp up quickly on unfamiliar codebases: tracing code paths, understanding existing features and conventions, and making changes that fit the established design.
• Strong API engineering skills: REST/HTTP semantics, API contracts, validation, error handling, pagination, versioning, and OpenAPI documentation.
• Distributed-systems fundamentals: timeouts, retries, circuit breakers, rate limiting, idempotency, caching, and graceful degradation.
• Experience with Kafka or RabbitMQ and event-driven/asynchronous communication patterns.
• Solid relational database skills with PostgreSQL or MySQL: schema design, SQL, transactions and isolation, indexing, query optimization, and schema migrations (e.g., Flyway/Liquibase).
• Working knowledge of NoSQL data modeling, querying, indexing, consistency, and performance; Elasticsearch/OpenSearch experience is valuable.
• Experience using Redis (or a comparable distributed cache) for caching, session state, or rate limiting, including cache invalidation and TTL strategies.
• Strong automated-testing practices with JUnit 5, Mockito, AssertJ, Spring Boot Test, and Testcontainers; integration and contract testing expected.
• Application security fundamentals with Spring Security: TLS, JWT, OAuth 2.0/OpenID Connect, authentication vs. authorization, secrets management, and secure API development.
• Hands-on Kubernetes deployment experience, including Helm: writing and maintaining charts, values management across environments, Kubernetes configuration (ConfigMaps, Secrets, readiness/liveness/startup probes, resource requests and limits), horizontal scaling, and rollout/rollback strategies.
• Practical scripting with Shell and/or Python for automation, diagnostics, build/deployment tasks, and developer tooling.
• Git, Maven or Gradle, CI/CD pipelines, and production observability through structured logs, metrics, and traces (OpenTelemetry).
• Hands-on experience with production observability tooling — at least one in each category: metrics/dashboards (Prometheus, Grafana), log aggregation (Splunk, ELK/OpenSearch Dashboards, Loki), and APM (New Relic, Datadog, Dynatrace, or Azure Application Insights) — for monitoring, alerting, and troubleshooting live services.
• Ability to communicate trade-offs clearly, review code constructively, and take ownership of services in production.
