Description
Principal Software Engineer, AI Platform
Team: Software Engineering
Location: San Francisco, Los Angeles
Commitment: Full-Time
Workplace Type: remote
WHAT YOU WILL BE DOING
Lead the design, development, and scalability of core Java-based backend services that power our multi-tenant platform.
Architect and optimize platform components to support high-throughput, low-latency, and mission-critical workflows.
Integrate and manage core data systems (e.g., relational DBs, Redis, Elasticsearch, LDAP) to ensure performance, availability, and fault tolerance.
Drive the modernization of backend services, refactoring legacy Java components and adopting modern patterns (e.g., reactive programming, event-driven architectures).
Champion best practices for Java development, testing, observability, and deployment in a distributed, microservices-based environment.
Collaborate cross-functionally with teams across DevOps, Security, SRE, and Application Engineering to build robust platform capabilities.
Evaluate and implement scalable solutions for authentication, authorization, tenant isolation, and configuration management.
Mentor engineers across teams in deep Java design principles, debugging complex issues, and engineering for reliability.
Develop and maintain platform APIs, service orchestration logic, and critical workflows that support core business operations.
Identify and remediate bottlenecks in Java services, JVM performance, GC tuning, thread management, and memory footprint.
Build automation and guardrails for developer productivity and service reliability (CI/CD pipelines, code linting, config-as-code, etc.).
Partner with architecture and leadership to drive long-term technical strategy and platform evolution.
WHAT YOU BRING
10+ years of experience in Software Engineering with a strong focus on Java, Spring Boot, and distributed system design.
Proven track record of building and maintaining scalable backend platforms supporting millions of users or high concurrency.
Deep understanding of the Java ecosystem, JVM internals, memory management, performance tuning, and multithreading.
Hands-on experience with data systems such as PostgreSQL/MySQL, Redis, Elasticsearch, and LDAP.
Experience designing and supporting multi-tenant architectures, including isolation, resource control, and config management.
Strong experience in building and managing RESTful APIs, microservices, and platform-level abstractions.
Familiarity with infrastructure and deployment environments including Kubernetes, Docker, and AWS (or other cloud providers).
Solid knowledge of observability tools (e.g., Prometheus, Grafana, OpenTelemetry) and log management (e.g., ELK stack).
Experience integrating authentication and identity providers (LDAP, SSO, OIDC) into Java services.
Strong command of DevOps and automation practices (CI/CD, GitOps, IaC tools like Terraform, Helm, or Ansible).
Proven leadership in cross-team collaboration, mentoring, and influencing architectural direction.
Excellent analytical, problem-solving, and communication skills.
