Full Stack Development Engineer

PDF Solutions•Vancouver, BC

About The Position

PDF Solutions is redefining the way the semiconductor industry approaches data, analytics, and experience design. As part of our journey, we’re building Next gen platform — a modern, human-centered analytics platform. We believe design systems aren’t just about consistency — they’re about scalability, collaboration, and performance. This Full Stack Developer owns the ongoing development and maintenance of the Sapience® Manufacturing Hub enterprise (SMHe) product — a cloud-native platform that unifies manufacturing, shop-floor, and process data into enterprise business systems. They will be responsible for building and maintaining SMHe's own back-end services in Java and Spring Boot (microservices, REST APIs, data access against Oracle and Cassandra, Kafka-based messaging), the customer-facing SMHe web UI, the security and IAM layer, and observability — then shipping it all on Kubernetes via Helm across cloud, on-premises, and air-gapped environments. The developer delivers the platform features customers depend on, such as custom monitoring dashboards and end-to-end certificate management. Equally important is keeping the product healthy over its lifecycle: fixing defects, refactoring, raising test coverage, hardening security, and guaranteeing upgrade safety and backup/restore across releases. The role calls for solid grasp of the platform's architecture — high-availability and disaster-recovery topologies, RBAC, and PKI/TLS — and proven agentic development skills, meaning fluency with AI coding agents to accelerate and improve delivery, backed by concrete evidence (repos, PRs, before/after metrics). Familiarity with Apache Camel and the Karavan visual designer is a plus, but it is supporting context rather than the core of the role.

Requirements

Minimum of 8 years of experience
Strong Java (17+) and Spring Boot — building and maintaining production microservices and REST APIs.
Spring ecosystem depth: Spring Data / JPA, Spring Security, and Spring for Kafka.
Relational and NoSQL persistence — Oracle (SQL, schema/migration design) and Cassandra (data modeling, drivers).
Event-driven development with Apache Kafka (producers, consumers, serialization, error handling).
Front-end / full-stack web development for the SMHe UI (modern JavaScript/TypeScript SPA; specific framework per the codebase).
Containerization and orchestration: Docker, Kubernetes, and Helm.
Security engineering: OAuth2 / OIDC / JWT, RBAC, and identity integration with Keycloak (SMHe IAM); TLS/PKI fundamentals including corporate-CA certificates, Java truststores, and certificate lifecycle.
Observability instrumentation with Micrometer / Spring Boot Actuator, Prometheus, and Grafana.
Git-based source control and CI/CD pipeline contribution.
Proven agentic development skills with Claude Code or Cursor — demonstrated, hands-on use of AI coding agents to implement, refactor, test, and document software, with concrete evidence (repositories, pull requests, or before/after productivity metrics).
Solid grasp of distributed-systems architecture: high availability, replication, and upgrade-safe, backup/restore-friendly design.

Nice To Haves

Semiconductor or Manufacturing industry experience preferred
Apache Camel and the Karavan low-code visual designer.
Infrastructure automation with Ansible.
Experience with air-gapped or regulated/enterprise PKI deployments.

Responsibilities

Develop and maintain SMHe's back-end services and microservices in Java and Spring Boot — REST APIs, business logic, scheduled jobs, and service-to-service integration.
Build full-stack product features end to end, spanning back-end services and the SMHe web UI, including customer-facing monitoring dashboards (Grafana), panel thresholds, and alerting.
Enable logging and auditing within the product, internally and through integration with entrerprise solutions such as splunk or Dynatrace. Use and management of Elastic/Opensearch to gather and analyze data.
Implement persistence and data access against Oracle (RAC) and Cassandra using Spring Data / JPA and appropriate drivers, ensuring data integrity, migrations, and upgrade-safe schemas.
Integrate Kafka-based messaging through Spring (producers, consumers, serialization, and error handling) for event-driven product capabilities.
Maintain product quality across releases: triage and fix defects, refactor, raise unit and integration test coverage, perform code reviews, and manage technical debt.
Build security into the the product: Spring Security / OAuth2 / OIDC / JWT integration with SMHe IAM (Keycloak), fine-grained RBAC, and end-to-end TLS/PKI — corporate-CA certificates, Java trust stores, Kubernetes TLS secrets, NGINX ingress, mutual TLS, and certificate rotation/revocation (CRL/OCSP).
Code with security in mind: develop and review code for best practices, respond swiftly to change or update code, libraries and dependencies to address CVEs.
Guarantee persistence, upgrade safety, and backup/restore for customer-managed artifacts (dashboards, thresholds, alerts, certificates) across pod restarts and version upgrades.
Containerize and ship services with Docker, Helm, and Kubernetes; instrument with Micrometer / Spring Boot Actuator to expose Prometheus metrics and Grafana dashboards; support cloud, on-prem, and air-gapped builds.
Manage source control in Git and contribute to CI/CD pipelines: branch, build, deploy, roll back, and version product releases.
Demonstrate agentic development skills by using AI coding agents to implement, refactor, test, and document features, with evidence of measurable productivity and quality gains.
Build agentic and automated capabilities into the product where they add value — self-service workflows and automated monitoring, alerting, and remediation.
Author developer and operator documentation, and collaborate with support teams and customer admins to reproduce and resolve product- and platform-level issues.
