[Hiring] Full Stack Developer @Magellan AI

Role Description

We are looking to hire an experienced full-stack developer to join our team of seven engineers, to help launch a major new feature and continue to enhance our core product. The job has changed shape over the past year:

• Adding new features to our Ruby on Rails application from top-to-bottom, full stack.
• Directing AI coding agents through real work: framing the problem and its constraints, reviewing what comes back line by line, pushing back when a solution has outgrown the problem, and starting over simpler when that is the right call.
• Increasing system/code quality by using practices such as TDD and refactoring.
• Writing the design down before the code: specs, architecture decision records, and product documentation for our operations team.
• Extending our own tooling — the skills, subagents and CLI helpers that encode how we work.
• Building AI-facing product surfaces, like our Ad Intelligence MCP server.
• Enhancing usability of existing features via Turbo/Stimulus and other front-end improvements.
• Troubleshooting and fixing performance issues and complicated logic across Postgres and ClickHouse.
• Experimenting and providing stopgap solutions for potential opportunities.
• Sharing in providing operational support to make sure the system stays running and address any bugs.
• Experimenting via internal hackathons to produce novel solutions and feature enhancements.

Qualifications

• 3+ years of software development experience
• Expertise with Agile web development, with practices such as TDD and Refactoring
• Fluency working with AI coding agents day to day, or the obvious appetite for it.
• Clear writing skills for writing specs, ADRs, and documentation.

Requirements

• Nice to Have:
• Ruby on Rails
• ClickHouse
• Python
• NYC-based
• Experience designing MCP servers or other LLM-facing APIs
• Background in ad tech
• Interest in the podcasting world

Benefits

• Competitive base salary and bonus structure
• Medical, dental, and vision coverage - individual coverage is free
• Company-subsidized family coverage
• Home office improvement reimbursement up to $500 per year
• Company laptop and external monitor
• 11 company holidays
• 20 PTO days for vacation, illness, and personal time
