- Own core systems critical to our contributor platform, with direct impact on Scale’s GenAI data pipeline and business outcomes
- Architect and scale infrastructure capable of handling millions of tasks per week with high reliability and low latency
- Partner cross-functionally with ML teams, Forward Deployed Engineers, and Product to ensure data quality and operational excellence
- Contribute to a strong engineering culture while setting best practices for teammates through mentorship, code reviews, and process improvements
Requirements
- 5+ years of software engineering experience, ideally in high-growth, product-focused environments
- Proven track record of shipping production systems at scale
- Drive reliability and performance across critical infrastructure systems, ensuring our platforms scale predictably and operate with high availability
- Strong technical depth in one or more areas: front-end frameworks, distributed systems, data infrastructure, or developer tooling
- Experience working across the stack, ideally with React, TypeScript, Node.js, Python, MongoDB, Elasticsearch, and/or Temporal
- Strong product sense and ability to translate ambiguous problems into technical solutions
- Comfortable working in a fast-paced, high-ownership environment with a bias toward execution
