Descripción del empleo

Overview

You are a senior engineer with strong skills in Java and/or Kotlin, building secure, observable, cloud-native services on Azure. You are comfortable designing containerized microservices, deploying to Kubernetes, and making pragmatic architectural trade‑offs. You pair strong implementation skills with the ability to step back, evaluate patterns, and propose resilient, evolvable solutions.

Responsibilities

• Design and build containerized microservices (Java / Kotlin) with clear domain boundaries.
• Define and maintain OpenAPI specifications; drive contract-first API evolution.
• Write high‑quality unit, integration, and contract tests (coverage + meaningful assertions).
• Instrument services with structured logging, metrics, tracing, and health probes.
• Optimize use of data stores (relational, NoSQL, binary/object) based on access patterns.
• Apply security best practices (least privilege, secrets management, dependency hygiene, threat considerations).
• Contribute to event-driven patterns (producers/consumers, schema evolution, Kafka / streaming semantics).
• Support CI/CD and infrastructure as code (Terraform/Bicep or ARM, YAML pipelines, scripting in Bash/PowerShell Core).
• Participate in code reviews, pair/mob sessions, and iterative refinement.
• Provide mentoring and technical guidance to mid and junior engineers.

Tech Stack (Indicative)

• Area: Primary Tools / Technologies
• Languages: Java, Kotlin
• API: REST, OpenAPI, JSON, OAuth2/OIDC
• Runtime: Key Vault, Monitor, Storage, Managed DB (PostgreSQL / SQL), Kafka (if applicable)
• Data: Relational + NoSQL patterns; caching (Redis)
• Observability: Metrics, tracing (OpenTelemetry), structured logs
• Security: Managed identities, secret rotation, TLS, RBAC
• DevOps:

Required Qualifications

• Professional experience building production APIs in Java and/or Kotlin.
• Strong grasp of containerization and Kubernetes deployment patterns.
• Demonstrated use of Azure services (at least Key Vault + one data platform + monitoring).
• Solid understanding of HTTP semantics, RESTful design, and API lifecycle.
• Experience with event-driven architectures (streaming, pub/sub, consumer resilience).
• Proficient in automated testing: unit, integration, and (preferably) contract tests.
• Applied security knowledge: authentication, authorization, secret management, dependency risk awareness.
• Effective debugging and performance tuning (profiling, thread/heap analysis, query optimization).
• Clear written and verbal communication in English.

Nice to Have

• Exposure to Go (golang) for internal tooling or performance‑critical paths.
• Exposure to building APIs in a variety of programming languages.
• Experience with async messaging (Kafka) schema versioning or CDC patterns.
• Knowledge of distributed tracing correlation (W3C trace context) and SLO/error budget practices.
• Hands-on with resilience frameworks (e.g., Resilience4j) or service meshes.
• Previous work in insurance / fintech / regulated environments.

Ways You Work

• Constant learner who tracks industry and open source trends pragmatically.
• Collaborative mindset; promotes psychological safety and inclusive discussions.
• Bias toward incremental delivery and empirical validation (measure, adjust, repeat).
• Comfortable balancing refactoring with feature delivery.
