- Design data models and work with PostgreSQL, MariaDB, or similar SQL databases.
- Build and support distributed, asynchronous, and event-driven systems.
- Work with Kafka or similar event-streaming technologies.
- Own development from technical design through implementation, testing, deployment, and production support.
- Build observability into applications through logging, metrics, and tracing.
- Partner with Product, Design, and Engineering teams to deliver high-impact features.
- Mentor engineers and contribute to architecture, code quality, and engineering best practices.
- Help develop and improve AI-assisted and agentic development workflows using modern AI engineering tools.
What We're Looking For
- 5+ years of professional full-stack software engineering experience.
- Strong React, Next.js, and TypeScript experience.
- Strong backend development experience with Kotlin, Java, Spring, or comparable technologies.
- Experience designing and building REST APIs and distributed systems.
- Strong SQL and relational database experience.
- Experience with AWS, GCP, or similar cloud platforms.
- Experience developing and deploying applications in containerized environments.
- Understanding of asynchronous processing and event-driven architecture.
- Experience with Kafka or similar messaging/event-streaming platforms.
- Experience with observability technologies such as Grafana, OpenTelemetry, or similar tools.
- Experience incorporating AI development tools into software engineering workflows.
- Strong communication, problem-solving, and technical decision-making skills.
- Experience building consumer-facing, fintech, financial services, or other high-scale digital products is a plus.
Technology Environment: React, Next.js, TypeScript, Kotlin, Java, Spring, PostgreSQL, MariaDB, Kafka, AWS / GCP, Containers, Grafana, OpenTelemetry, AI-Assisted Development
This is an excellent opportunity for a Senior Engineer who enjoys working across the entire stack, wants ownership of meaningful production systems, and is interested in modern cloud, event-driven, and AI-assisted software engineering.
