The team at Pattern is leveraging our experience building sophisticated autonomous robots to address pressing industrial applications. Our robots operate both indoors and outdoors, around people and vehicles. We're riding the sweet spot between cutting-edge r&d and actual solution scaling. Our goal is to build the most capable autonomy systems for the most challenging unstructured environments in the solar system by quickly scaling, learning, and delivering real value by solving stepping stone applications immediately. We can do this because we love the thrill of adventure and exploration. The thrill of being pioneers. It's partly our Colorado roots, beckoning us to go faster/bigger/further than anyone before. We have mountains to climb! (figuratively & literally) .

Project Canary is a mission-driven B-Corp that helps reduce emissions in the energy, waste, and agriculture industries through independent assessment of carbon and environmental footprints. With offices in Denver and Austin, Project Canary achieves this goal by ingesting data from various sources, including its own proprietary environmental sensors, to calculate carbon emissions from different facilities in real-time. The resulting independent, trusted data can inform the procurement of offsets in real-time using microtransactions, formulate the data-driven ESG strategy that investors now demand, improve operations by identifying problem areas in minutes, and bolster customer engagement through radical supply chain transparency. Initially, Project Canary is focused on the energy industry. With thousands of energy assets analyzed and hundreds of environmental and air quality sensors currently deployed, Project Canary is positioned better than anyone to provide empirical ESG data. Project Canary’s success is attributed to the motivation, skill, and teamwork of its employees. The team understands the importance of maintaining a culture where relationships are valued, feedback is crucial, and trust in each other and our products/services is paramount. If you enjoy a fast-paced environment, mission-driven work, and being a valued member of a motivated diverse team, we want to hear from you.

At Aligned, we’re building a new type of company that brings great engineers, designers, and product managers together onto remote squads. We create product and engineering teams that move as one, aligned with company missions, values, and visions.

IR Labs is an applied AI studio and a venture of Integrated Research Limited. We build products where AI meets hard engineering problems, and we run them as real businesses. Our first product, Agentic SQA, is live. It investigates pull requests in C codebases and reports likely defects with evidence: the suspected failure mode, the exact scope and the next step. When nothing clears the bar, it stays silent. It runs on real repositories today, it is generally available and customers pay for it. It was built for the hard layer. Kernel modules, device drivers, firmware, embedded targets and the C libraries everything else stands on. The code where a bad merge costs weeks, not minutes. AI solved writing code. Trusting it is the harder problem, and verification is the scarce layer. That is the company. We are a small senior team, US based and fully remote, working in cross-functional squads across AI and ML, data infrastructure, systems, compiler engineering and product. We look for deep technical ability, strong systems judgment and a bias toward proving ideas in working systems. We are comfortable being wrong fast and changing direction when the data says to. Before you talk to us, use the product. Form your own view. Every conversation we have starts with what you saw.

The only conversational AI platform for Self Storage. When others close their doors at 6PM, you’re still open. 24/7 in fact. You’d be surprised at how many people are looking to rent storage units at 2AM. The goal of automation should be to make the lives of people easier—whether those people are your customers or your facility manager. Automation eliminates repetitive and tedious tasks—freeing up people to spend their time on more worthwhile activities.
