Job Description
Senior Software Engineer – Data Platform
LightBox
• Design and implement API gateways, model routing layers, and service infrastructure that connect fine-tuned CRE models with production applications. • Develop internal developer tooling - prompt management interfaces, evaluation dashboards, trace viewers - that accelerate the team's ability to ship and iterate on AI features. • Implement integration patterns for embedding AI capabilities into LightBox's existing workflow applications, ensuring seamless user experiences. • Build observability and monitoring infrastructure for AI workloads: latency tracking, quality metrics, cost attribution, and usage analytics. • Contribute to the platform's knowledge retrieval and caching layers, optimizing for both accuracy and performance at scale. • Collaborate with ML engineers on model serving infrastructure, helping bridge the gap between training outputs and production deployment. • Participate in architecture decisions and technical design reviews, bringing a pragmatic full-stack perspective to the team's work.
Job Requirements
- 6+ years of software engineering experience with a strong full-stack foundation (backend-leaning preferred).
- Production experience building APIs, microservices, and platform infrastructure in Python and/or TypeScript/Node.js.
- Solid understanding of cloud infrastructure (AWS or GCP), containerization (Docker, Kubernetes), and CI/CD pipelines.
- Experience building developer-facing tools, SDKs, or internal platforms that other engineers consume.
- Familiarity with LLM integration patterns: API-based model consumption, prompt engineering, retrieval-augmented generation, and tool/function calling.
- Strong fundamentals in distributed systems, data modeling, and API design.
- Comfort working in a small team with high autonomy - you can own a feature end-to-end from design through deployment and monitoring.
