The roots of Blackbird Capital lie in combat operations, founded by an air force veteran. This military DNA is exactly what shapes our strict approach to risk: absolute discipline, tactical precision, and zero tolerance for chaos. Today, we apply that same battlefield execution to global financial markets, deploying systematic quantitative models to capture structural anomalies across equities, fixed income, and commodities. Because managing complex derivatives requires flawless cognitive readiness, we have zero tolerance for bad habits or dependencies. We require clean, sober, and sharp minds. Being physically active is a massive plus for us. We believe that physical endurance directly drives mental stamina and analytical clarity under pressure. However, we don’t believe in toxic corporate grind. Work is not your life. We operate with high intensity and expect high momentum, but we will never expect you to answer emails 24/7 or be chained to your screen around the clock. When you are on the clock, give us absolute focus. When the work is done, you disconnect. If you want a highly disciplined team, zero bureaucratic fluff, and real market impact, this is where you belong.

Learning for software developers is broken. Available options are boring, time-consuming, not relevant to everyone, or require the company to take a big productivity hit. We've designed a fast, effective training solution for tech teams that avoids those pitfalls. Targeted Capability Training is: - Core to how an engineering team operates, not a fringe add-on or an after-thought. - Learning that aligns with business priorities and changes what the team is capable of. And we’re called Skiller Whale because … well, our love of puns knows no bounds. Our mission is to change what tech teams are capable of. We’ve found the most effective way to accomplish this is through challenging, realistic exercises that can be explored and tackled in our interactive teaching model. We strive to be intelligent, playful learners, like our Orca, Ada (yes, we love a Lovelace reference). These principles define who we are, not only as a company providing a product, but also as a group of people working together. We believe that diversity makes us stronger and are dedicated to building a company that represents society as a whole. We value marginalised people’s safety over privileged people’s comfort. We value honest and open communication, and we believe that in order to foster an environment that enables this, it’s important that our team feel included, recognised and like they can bring their full selves to work.

FairwAI is building real-time accountability infrastructure to detect bias in the moments that matter most. We’re solving one of the toughest challenges in tech: how to make fairness not just a principle but a system. From healthcare and hiring to hospitality and housing, bias shows up when people are most vulnerable. FairwAI turns those moments into measurable, actionable data—using AI, computer vision, and behavioral science to flag risks and enable institutional change before harm happens. We’re not a DEI tool. We’re compliance infrastructure for a new era—where safety, dignity, and fairness are non-negotiable. Our team includes engineers, policy thinkers, civil rights advocates, and public interest technologists from MIT, Harvard, Stanford, The UN, and beyond. We’re launching high-impact projects and building the backbone of ethical AI adoption across sectors. For interns & fellows, this is not a coffee-run experience. You’ll co-design tools, analyze live scenarios, and help shape the future of bias detection and remediation. Your work will be mentored, respected, and turned into real-world impact. If you care about fairness, ethics, and building tools that actually change lives—FairwAI is where your skills meet purpose. Join us. Let’s build the infrastructure fairness deserves.
