Ruby on Rails Developer
Front end developer job in San Mateo, CA
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. The co-founders, Ajith and Avinash, have known each other for over 18 years and are on a life mission to help SMBs become wildly successful.
We are just getting started, and our vision is to build the AI Operating System for home services. If you vibe with this and want to be a part of the team, read on!
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.
About the job
We're all-in on Ruby on Rails, and our platform is a majestic monolith with a voice orchestration layer. Of course, we use "AI" with various LLMs, STT, and TTS models. We ship fast and continuously without running in circles, delivering work that matters.
As a founding team member, you'll be working very closely with Avinash, the co-founder & CTO to build the product. I love working with smart people who simply love building products. You will have the autonomy to own and ship features end-to-end. 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're a self-starter manager-of-one who can take ownership of large features - architect, build, and deploy them to production independently. 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! You must also be comfortable with the staples of full-stack web development: HTTP, HTML, JavaScript, and CSS.
We care about what you can do and how you do it, not about your credentials. Whether you have a Computer Science degree or took a different path, what matters to us is your skill set, your mindset, and your ability to deliver.

Competitive salary: $120-150k base salary + meaningful equity
Work in person with an energetic, highly collaborative team!

UI/UX Designer, Design Language
Front end developer job in San Francisco, CA
About Sift
At Sift, we're accelerating the advent of next-generation machines, improving life on and off the planet. We're at an inflection point where connected machines will shape nearly everything we do, and Sift is building the data infrastructure that underpins their engineering, manufacturing, and operation.
Our system is inspired by processes and software built at SpaceX for Dragon, Falcon, Starlink, and Starship. We're a fast-growing startup with engineers and operators from SpaceX, Google, Palantir, and Astra, backed by top investors in the sector. We're looking for high-performing teammates to define how Sift is experienced, from core product to customer touchpoints.
About the Role
We're hiring a UI/UX Designer to create and own Sift's visual design language - shaping how engineers interact with our platform.
This is not a surface-level branding role. You'll work closely with product, engineering, marketing, and leadership to design intuitive, scalable systems that let users stay in flow while tackling complex technical problems. You'll build a design system that reflects the sophistication of Sift and scales across every product surface.
Key Responsibilities
Define and maintain Sift's design system, including reusable components and patterns.
Translate complex architectures and telemetry workflows into clear, intuitive visuals.
Visualize large-scale, high-frequency data in ways that are both beautiful and informative.
Partner with marketing, product, engineering, and customers to ensure design resonates with technical users.
Create reusable templates, frameworks, and patterns to increase speed and consistency.
Ensure every design reflects the precision and quality of Sift's platform.
Act as a visual translator, bridging technical complexity with design clarity.
What You Bring
8+ years of experience in UI/UX, design systems, or data visualization.
Strong portfolio demonstrating visual clarity, systems thinking, and technical storytelling.
Experience designing for B2B SaaS or infrastructure-oriented products.
Proven ability to transform technical input into clear visual outputs (diagrams, workflows, visual systems).
Comfort working independently while leading cross-functional projects.
Proficiency in Figma; familiarity with motion design or front-end implementation a plus.
Clear communication skills; able to explain design rationale to technical and non-technical stakeholders.
Curiosity for technical audiences, complex systems, and design problem-solving.
Bonus Points
Experience in aerospace, defense, autonomy, or energy.
Background in system modeling (mechanical, software, or process).
Prior work on developer documentation, architecture explainers, or product walkthroughs.
Portfolio Required: Please include a link to your portfolio or design examples. Applications without visual work samples will not be reviewed.
Location:
We're looking for candidates who can collaborate in person twice a week in the SF Bay Area and join the team at Sift's headquarters in El Segundo, CA for a full week every two months. We're open to relocating candidates to San Francisco or considering those already based in the Los Angeles area for the right fit.
Salary range: $160,000 - $200,000 per year. Plus equity and benefits.
Eligibility:
U.S. Person Required: Must be a U.S. citizen, lawful permanent resident, or protected individual such as an asylee or refugee in compliance with ITAR (International Traffic in Arms Regulations) / EAR (Export Administration Regulations) regulations.
