Build robust observability, monitoring, logging and cost-management capabilities.
Identify and address architectural risks ahead of deployments with design partners.
Review, test and refactor AI-assisted code produced using tools such as Claude and Codex.
Introduce pragmatic engineering standards across testing, documentation and code quality.
Shape the long-term technical architecture as the company progresses from pre-commercial development to customer deployments.
Skillset
Significant software engineering experience at Principal, Staff or Senior Staff level.
Deep expertise in backend engineering and distributed systems architecture.
Hands-on experience building proxies, gateways, networking infrastructure or high-performance data-processing systems.
Strong proficiency in at least one systems or backend programming language, ideally Rust or Java.
Experience designing, deploying and operating production infrastructure on AWS.
A strong understanding of system reliability, scalability, latency and performance optimization.
The ability to assess an early-stage codebase and implement pragmatic architectural improvements.
Experience working within startups, innovation teams or similarly fast-moving and lightly structured environments.
The confidence to work independently while collaborating closely with a technical co-founder.
Familiarity with AI infrastructure, model gateways, observability or FinOps is a plus.
