We’re hiring a senior full-stack engineer to make a major contribution across the LCI platform. You’ll ship features end-to-end on our Ariadne product, strengthen the shared services and libraries that every team depends on, and help shape new greenfield initiatives. The work spans backend services in Kotlin/Spring Boot, a React/TypeScript frontend, and the cloud infrastructure that ties them together. You’ll own problems from fuzzy idea to production — designing, implementing, shipping, watching them run, and iterating.
Core Functions of the Role
- Design, build, and maintain backend services and APIs that power our customer-facing applications.
- Build and evolve frontend features in React/TypeScript that surface those capabilities to end users.
- Contribute to and improve the shared libraries (API models, auth, messaging, AWS utilities) used across our microservices ecosystem.
- Take on greenfield work — propose architecture, build the first version, and iterate based on real usage.
- Collaborate across engineering, product, and design to define requirements, iterate quickly, and deliver reliable releases.
- Participate in planning, design, code review, deployment, and on-call rotation using Agile practices.
- Propose pragmatic solutions and improvements that directly influence product direction.
Required Qualifications
- 5+ years of professional software engineering experience building and operating production systems.
- Strong backend fundamentals: API design, testing, debugging, performance, and operational thinking.
- Production experience in Kotlin or another JVM language (Java/Scala). Kotlin strongly preferred.
- Production experience with Spring Boot and the broader Spring ecosystem (or demonstrated ability to ramp quickly with equivalent framework experience).
- Demonstrated production experience with React and TypeScript
- Experience working in a real microservices architecture with cross-service communication.
- Experience with at least one authentication/identity system (JWT, SAML/SSO, OAuth, passwordless).
- Experience with event-driven systems and message brokers (RabbitMQ, SQS, Kafka, or similar) and the eventual-consistency trade-offs they imply.
- Experience building B2B SaaS, ideally multi-tenant.
- Solid understanding of relational databases (PostgreSQL preferred), data modeling, and query patterns.
- Comfortable working in a small team with high ownership and ambiguous problems.
Preferred Qualifications
- Experience with Redis (caching, pub/sub) in production.
- Experience with Elasticsearch / OpenSearch in production.
- Experience with Hibernate / JPA, including audit-logging frameworks (e.g., Envers).
- AWS depth — S3, SQS, Secrets Manager, ECS, Lambda, CloudFront.
- Containerized deployment experience (Docker, ECS, CI/CD).
- Experience with SAML2 / SSO federation (e.g., OpenAthens, Okta, Azure AD).
- Experience integrating LLMs or AI workflows into production applications.
- Experience with Gradle (Kotlin DSL) and multi-module JVM builds.
- Awesome Extended Health Care Plan
- Dental Care
- Life & Disability insurance
- Health spending accounts
- Unlimited Vacation Leave
- 12 Paid Holidays
- $3,000 Employee Referral Program
- Employer contribution to VRSP
- Rewards and recognition programs
