Principal AI-Native Software Engineer

The posting, as ButterflyMX wrote it

OUR MISSION

ButterflyMX is on a mission to empower people to open and manage doors & gates from a smartphone. Our products are installed in more than 20,000+ multifamily, commercial, gated communities, and student-housing properties worldwide, including properties developed, owned, and managed by the most trusted names in real estate. Our features are designed for developers, owners, property managers, and tenants and our products lower operating costs and improve tenant satisfaction.

OUR SOLUTION

Developers and owners no longer need to run building wiring or install in-unit hardware. Property managers can grant building access, revoke permissions, and review entry logs from an online dashboard. Residents can open doors from their smartphones, issue visitor access, and see who is trying to enter the building.

OUR CULTURE & VALUES

Fantastic people are the key to our success. As a distributed, primarily remote workforce, we’re looking for more intelligent, passionate, collaborative, ai-forward, and down-to-earth individuals to join our growing team. We’re driven by a shared commitment to excellence and innovation, grounded in our core values: We delight our customers, We take ownership, We are a community of collaborators, We speak up, We think big and do small, and We are tenacious.

ROLE OVERVIEW

We are looking for an exceptional Principal or Staff-level engineer who has fundamentally changed how they build software because of AI. This is not a traditional software engineering role with an AI assistant bolted on. We want someone who uses AI agents, especially Claude Code, to independently take well-defined product initiatives from business requirements to secure, tested, production-ready software.

The ideal candidate is an excellent backend engineer first, grounded in our stack: TypeScript services, MongoDB and relational data, and cloud infrastructure across AWS and GCP. AI dramatically increases your output, but your engineering judgment is what makes that output valuable.

In this role, you will work closely with our Product and Design teams. You will operate with unusually broad engineering ownership. You may clarify requirements with Product, develop the technical specification, work through implementation details with Design, coordinate multiple coding agents, review their work, deploy the application, manage its infrastructure, and continue improving the product after launch.

The ideal candidate is already working this way. You routinely operate several Claude Code sessions or agents in parallel. You know how to divide work across agents, provide them with the right context, establish effective feedback loops, and keep multiple workstreams moving without losing control of quality or architecture.

You believe manually writing code should become a relatively rare part of software development. But you are not impressed by code merely because an AI generated it. You recognize over-engineered "AI slop," unnecessar

across unfamiliar programming languages, frameworks, and legacy systems, using AI to accelerate that work.

• Strong ownership, initiative, and bias toward building.
• Excellent written and verbal communication, particularly when expressing technical requirements, constraints, implementation plans, and engineering decisions to both business and technical audiences.

COMPENSATION

The expected base salary range for this position is $215,000 –$250,000. Actual compensation will depend on factors including budget, skills, experience, location, and internal equity. This position may also be eligible for bonuses, equity, or other forms of compensation, where applicable.
