Job description
Kensho Technologies is S&P Global’s hub for AI innovation and transformation. With expertise in machine learning, natural language processing, and data discovery, we develop and deploy novel solutions to innovate and drive progress at S&P Global and its customers worldwide. Kensho's solutions and research focus on business and financial generative AI applications, agents, data retrieval APIs, data extraction, and more.
At Kensho, we hire talented people and give them the autonomy and support needed to build amazing technology and products. We collaborate using our teammates’ diverse perspectives to solve hard problems. Our communication is open, honest, and efficient. We dedicate time and resources to explore new ideas, always rooted in engineering best practices. As a result, we can innovate rapidly to produce technology that is scalable, robust, and useful.
Kensho’s Applications group develops the web apps and APIs that deliver Kensho’s AI capabilities to our customers. Our teams are small, product-focused, and intent on shipping high-quality code that best leverages our efforts. We’re collegial, humble, and inquisitive, and we delight in learning from teammates with backgrounds, skills, and interests different from our own.
Our App Experiences team focuses on breathing life into novel ML capabilities, translating them into valuable and intuitive end-user experiences. We collaborate closely with our Product and Design teams to understand user needs, looking for creative applications and delivery mechanisms of our technology. We demo early and often, and we keep a tight iteration loop. We sweat the details when it comes to UX.
As a Senior Full‑Stack Software Engineer, you will build AI‑centric web applications in TypeScript ranging from experimental POCs to full‑fledged product offerings. You'll have significant autonomy over technical and architectural choices, and be responsible for managing short‑ and long‑term trade‑offs. The ideal candidate loves product and views technology as a means, not an end, and is excited to collaborate across all aspects of the software development lifecycle.
At Kensho, we believe in flexibility‑first, and give our employees the opportunity to work from where they feel most productive and engaged (must be in the United States). We also value in‑person collaboration, so there may be times when travel to one of our Kensho hubs (e.g., Cambridge, MA or NYC) will be required for team meetings or company events.
Kensho states that the anticipated base salary range for the position is 150k–225k. In addition, this role is eligible for an annual incentive bonus and equity plans. At Kensho, it is not typical for an individual to be hired at or near the top of the range for their role and compensation decisions are dependent on the facts and circumstances of each case.
What You’ll Do
Build full‑stack and SPA TypeScript applications ranging from experiments to flagship products
Collaborate on product decisions and communicate technical constraints and considerations
Own and collaborate on technology/architecture decisions and conventions
Teach and learn from the team and the broader organization via mentorship, code review, knowledge sharing, etc.

At least five years of direct experience building commercial web applications in JavaScript/TypeScript
At least three years of that experience working directly on web UIs in a modern framework
At least one domain of deep technical expertise (e.g., web performance, design systems, framework knowledge, etc.)
Product sense, or a strong interest in developing it
Kind, thoughtful, and high‑signal communication skills for both technical and non‑technical audiences
Ability to translate ambiguous needs and constraints into clear technical requirements
