About Us
Spare builds the Operating System for Cities. We power microtransit, paratransit, fixed-route, and municipal operations in 250+ cities worldwide. We are an aggressively AI-first company, rethinking how modern software is designed, built, and shipped.
About This Role
We are looking for a Junior AI-Accelerated Developer to help us dramatically increase engineering velocity by partnering closely with our COO and engineering team. This role is ideal for an ambitious junior developer who is excited about AI-assisted coding, eager to learn, and able to move quickly. You will report directly to Josh, our Co-Founder and COO.
You will work within Cursor, Claude Code, GitHub, and our engineering workflows to help iterate on code, address review feedback, maintain branch health, and push features from concept to merge. You won’t own architecture or complex systems yet. Instead, you’ll focus on accelerating delivery, improving code quality, and ensuring a smooth path through our development pipeline.
This is a new type of engineering role, combining software fundamentals with strong operational instincts and deep proficiency with AI coding tools.
Key Responsibilities
AI-Assisted Engineering
Work inside Cursor and Claude Code to iterate on code based on reviewer feedback
Translate high-level instructions into precise prompts to guide AI-generated code
Improve AI-generated code until it meets internal quality standards
Help refactor, clean up, and polish code before final review
Branch, Build and CI Management
Maintain functioning local and remote environments
Pull branches, resolve simple merge conflicts, rebase, and ensure builds run cleanly
Keep PRs unblocked by ensuring CI, linting, type checks, and tests pass
PR Execution and Throughput
Push commits and update branches rapidly based on reviews
Work through automated feedback (Meticulous, linters, TypeScript errors)
Re-request reviews and ensure PRs move swiftly through merge queues
Quality and Reliability
Apply checklists and QA steps before senior engineer review
Catch common issues the AI may miss, such as naming, structure, and missing edge cases
Ensure final code is clean, idiomatic, and consistent with our best practices
What Success Looks Like
Features vibe-coded by Product move quickly from prototype to polished to merged
Senior engineers spend minimal time on minor fixes or environment switching
You become highly skilled at working with AI tools and accelerating engineering throughput
Who You Are
Strong technical curiosity and the ability to learn quickly
Excellent attention to detail, especially in code quality
Ambitious, excited about AI-assisted coding, and able to move quickly
Requirements
1 to 2 years of hands-on experience with software development (internships welcome)
Basic familiarity with TypeScript, React, or Node.js
Comfortable with Git, PR workflows, and debugging build issues
Strong written and verbal communication skills including the ability to follow precise instructions
It will be considered a plus (nice-to-have):
Experience with AI coding tools (Cursor, Claude Code, GitHub Copilot)
Experience in frontend engineering or fullstack frameworks
Familiarity with monorepos (Nx), microfrontends, or modern React architecture
Don’t meet every single requirement?
Studies have shown that women and people of colour are less likely to apply to jobs unless they meet every single qualification in the job posting.
At Spare, we are committed to creating a diverse and inclusive environment, so we strongly encourage you to apply even if you don’t believe you meet every single qualification outlined. We also do our best to respond to all applications we receive.
Why Join Us?
Work directly with a founder on fast-moving, high-impact product initiatives
Gain hands-on experience with next-generation AI development workflows
Accelerate your career faster than in a traditional junior developer role
Become an expert in AI-assisted engineering, a skillset that will define the next decade
If you are excited to master AI-assisted engineering and help ship great products at speed, we’d love to hear from you!
