About the Role

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 green‑field 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 green‑field 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.
