Come Work At Cactus! We are the 24/7 AI copilot built specifically for home services companies (plumbing, HVAC, electrical). It answers every call, qualifies leads, follows up, and books jobs - ensuring no opportunity is ever lost, day or night. We are a team of builders who are not afraid to create products in the most unconventional way.

About Cactus & the team We're a well-funded (read our latest funding announcement), YC-backed seed-stage startup with a mission to build the AI Operating System for SMBs. We're still in the early days, and you will get to shape the product. We have seen great traction and product-market fit with customers who love what we've built. We've built something truly special that's making a real impact in the small business space. We're a no-nonsense team of high-performing contributors and builders, and we wear multiple hats. We are in-person, working out of San Mateo. Here are the core values and principles that define us: Product at Core: Our mission is to go beyond utility, sparking joy and delivering real value with product. We design with the user in mind, ensuring that every interaction is meaningful, intuitive, and leaves a smile! One Team Always: We are the best of the best, holding ourselves to the highest standards. We push together for collective success-when one wins, we all win; when one struggles, we all step up to support. Being Nice: We default to kindness and respect in every interaction. It's about choosing empathy, practicing patience, and creating a culture where being nice isn't just encouraged-it's our natural instinct. Focus and Execute: We focus on action and rapid learning, using each experience to drive growth. By building, testing, and refining quickly, we ensure every step brings us closer to a bigger impact.

Your role will involve developing new features, shaping the product, building and scaling our AI platform, internal tools, integrations, and most importantly, ensuring our entire tech-stack is robust About You You take pride in your work and have always done an excellent job everywhere you've gone. We have an ambitious goal, and as such, we've built a team of A-players. If you want to work with others like you, this is the place.

You must enjoy writing code (yes, we love to vibecode) and creating delightful products. As with all early-stage startups, you're excited to wear multiple hats and eager to learn. Having experience building web applications end-to-end with Ruby on Rails is key. Some experience with implementing AI will be a plus!

WindBorne Systems is supercharging weather models with a unique proprietary data source: a global constellation of next-generation smart weather balloons targeting the most critical atmospheric data. We design, manufacture, and operate our own balloons, using the data they collect to generate otherwise unattainable weather intelligence. Our mission is to eliminate weather uncertainty, and in the process help humanity adapt to climate change, be that predicting hurricanes or speeding the adoption of renewables. We are building a future in which the planet is instrumented by thousands of our microballoons, eliminating gaps in our understanding of the planet and giving people and businesses the information they need to make critical decisions. The founding team of Stanford engineers was named Forbes 2019 30 under 30 and is backed by top investors including Khosla Ventures. You get to do every engineer's dream-push features for which you are the user. But first you must become the user! Unlike a traditional software engineering role, you will be directly involved in day-to-day meetings and decision-making related to flight automations, navigation and quality control. WindBorne Systems operates the world's largest constellation of autonomous weather balloons. We achieve full atmospheric coverage by manufacturing balloons at our headquarters in Palo Alto, and launching them from our 10 launch sites across the globe. Importantly, we only find out whether we're doing a good job when the balloon goes into the air. Although things like the balloon launch process and manufacturing revision systems may not seem directly relevant to flight, they are paramount to understanding flaws in our systems and subsequently propagating those flaws to the appropriate parties. In short, to become the best operations software engineer possible, you need to be armed with context and curiosity. This is fundamentally an operational role and one of your core responsibilities will be doing operational tasks. This job is not for if you want a chill job, or want to sit in a room by yourself and push code. To be good at this role, you must be a competent web developer. But to be great, you must be a holistic problem-solver. We capture huge amounts of information about our constellation through downlinked telemetry and our flight database. In this role, you'll be tackling the challenge of combining said data into a digestible and useful form. This can be through a new process, automation, abstraction, bugfix, quality of life change or even just a meeting. This is an opportunity to not only become a better software engineer, but also a better systems thinker, communicator and designer. In this role, you'll be given full ownership of load-bearing and mission-critical systems from day one-and live with the outcomes. If you want to grow fast, this is your shot. Responsibilities Serve as a web developer for our mission control dashboard Develop tools to facilitate manufacturing quality loop closure and improve flight performance Lean into chaos and immerse yourself in day-to-day operations Directly connect with our constellation of nearly 200 balloons Design systems that will scale from 200 to 10,000 balloons Interface directly with customers and fulfill real-time operational requests Preferred Skills Self-directed learning in ambiguous, low-structure environments Fundamentally curious problem-solver with bias towards action Strong work ethic and drive for constant improvement, balanced with the ability to work effectively in a team environment Ability to prioritize and execute tasks in a high-pressure, fast paced environment Excellent communication skills (oral and written) and the ability to clearly and concisely articulate complex problems to a wide variety of audiences Tech stack Ruby on Rails React Benefits 401(k) Dental insurance Health insurance Vision insurance Unlimited PTO Stock Option Plan Office food and beverages Salary $90,000-$130,000 *We are considering a range of backgrounds and experience levels for this position and will adjust our offers accordingly to be competitive with market rates.
