Founding Engineer- Nexon

Founding Engineer

Full-time

On-site

San Francisco

Seniority

• 1 4 years of experience as a backend-leaning Software Engineer or ML Engineer.

Role Overview

This is not a narrow backend role. You'll be building across classical backend systems and a frontier product area: reliable computer use in enterprise workflows.

The work spans APIs, infrastructure, automation, and AI-adjacent systems, with significant opportunities for ownership. You'll be joining during a period of rapid growth at a well-capitalized startup led by an experienced, second-time, exited founding team.

What You'll Do

• Build backend services, APIs, and data integrations, including data modeling and schema design.
• Develop infrastructure for AI-powered computer-use workflows, including orchestration, state management, and recovery.
• Improve observability, alerting, debugging, and production hardening.
• Own engineering relationships and feedback loops with customers.
• Build product features spanning deterministic code, browser automation, and model-driven execution.

Key Pain Points & Challenges

• Current models struggle with reliability when executing end-to-end workflows. The team is looking for engineers who can improve this.
• Seeking candidates who can tackle complex technical challenges and contribute to the company's rapid growth.

Work Experience

• Has shipped production-grade code in a full-time engineering role.
• Experience working at a high-growth startup or a top technology company.
• Experience in a customer-facing or forward-deployed engineering role.

Education

• Undergraduate degree from Harvard, Stanford, MIT, Princeton, Carnegie Mellon University (CMU), or Caltech. Open to candidates from a number of companies.
• Bachelor's degree in Computer Science or a related technical field.

Required Technical Skills

• Strong engineering fundamentals with demonstrated proficiency in Python.
• Experience productionizing machine learning models or building ML infrastructure.

Additional Requirements

• Must be able to work onsite in San Francisco, CA, five days per week.
• This is not a traditional 9-to-5 role.
