Senior Java Software Engineer

What you’ll build

• Design, build, and own high-performance backend services and APIs in Java 17/21, using Spring Boot, Spring Cloud, Quarkus, or Micronaut
• Architect microservices and event-driven systems with REST, gRPC, GraphQL, Kafka, RabbitMQ, or similar messaging platforms
• Model data and tune queries across PostgreSQL, MySQL, Oracle, MongoDB, Redis, and Elasticsearch, with attention to transactions, consistency, and scale
• Write clean, testable code with JUnit 5, Mockito, Testcontainers, and contract testing, and keep quality high through thoughtful code reviews
• Profile and tune the JVM: garbage collection, memory, threading, virtual threads, and concurrency, so services stay fast and predictable
• Containerize and deploy on Docker and Kubernetes across AWS, Azure, or GCP, working closely with platform and DevOps teams
• Build and improve CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI, ArgoCD) and ship small, safe, frequent releases
• Add observability with logs, metrics, and tracing (OpenTelemetry, Datadog, Grafana, Splunk, New Relic) and lead calm, blameless incident reviews
• Build secure services with OAuth2, OIDC, JWT, secrets management, and OWASP best practices, and support audits (SOC 2, PCI-DSS, HIPAA) where they apply
• Modernize legacy monoliths and older Java versions, including migrations to Spring Boot 3, Jakarta EE, and cloud-native architecture
• Write design docs and ADRs, lead technical discussions, and help the team make sound architecture decisions
• Mentor mid-level and junior engineers through pairing, reviews, and career conversations
• Use AI-assisted coding tools (Copilot, Claude, or similar) to speed up boilerplate, tests, and refactoring, while owning and reviewing every line that ships
• Partner with product managers, designers, QA, and security to turn fuzzy goals into reliable features
• Take part in a fair on-call rotation and keep runbooks and documentation current

Where you could grow

• Level Typical experience What you’ll own
• Senior Java Developer - 5-8 years : Services and features end to end, technical design for major initiatives, code review standards, and mentoring mid-level engineers
• Staff / Lead Java Engineer - 8-12 years : Architecture across multiple teams, platform and framework decisions, cross-team projects, and raising engineering standards
• Principal Engineer / Engineering Manager (optional paths) - 12+ years : Either company-wide technical strategy and deep individual-contributor influence, or people leadership with hiring, coaching, and delivery ownership

We use a dual career ladder with written promotion criteria and regular career conversations. Many of our engineers have moved into architecture, platform engineering, SRE, data engineering, and engineering management.

What you bring

Must have

• 5+ years of professional experience building production backend systems in Java
• Strong command of core Java: collections, concurrency, streams, generics, and modern language features (Java 11+)
• Hands-on experience with Spring Boot or a comparable framework, and with building and consuming RESTful APIs
• Solid experience with relational databases, SQL, and performance tuning
• Experience with automated testing, version control (Git), and CI/CD
• Understanding of distributed systems, microservices patterns, and tradeoffs such as consistency, resilience, and idempotency
• Clear communication in design reviews, code reviews, and with non-engineers
• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent experience. We care about what you’ve shipped.
• Authorization to work in the United States

Nice to have (not required)

• Cloud experience on AWS, Azure, or GCP, plus Docker and Kubernetes
• Experience with Kafka or other event streaming platforms
• Familiarity with Terraform, Helm, or other infrastructure-as-code tools
• Knowledge of Kotlin, Scala, or Python alongside Java
• Experience with reactive programming (Project Reactor, WebFlux) or virtual threads
• Background in fintech, healthcare, insurance, e-commerce, telecom, logistics, or the public sector
• Certifications such as Oracle Certified Professional (Java SE), AWS Developer or Solutions Architect, or CKAD (we’ll pay for exams and renewals)
• Open-source contributions, technical writing, or conference talks
• Experience integrating or building AI-powered features (LLM APIs, vector search, RAG)
• Public trust or security clearance, or willingness to obtain one [if applicable]
