Job Specifications

Kensho 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 much 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 with one another is open, honest, and efficient. We dedicate time and resources to explore new ideas, but 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 Full-Stack Software Engineer II, you will build AI-centric web applications in TypeScript ranging from experimental POCs to full-fledged product offerings. You'll work with the team to understand trade-offs and make technical and architectural decisions. You'll aim for high iteration velocity and optimize for learning. The ideal candidate loves product and views technology as a means, not an end, and is excited to gain familiarity with 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 130 -175k. 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
Collaborate on technical decisions and conventions
Quickly level up and learn from the team and the broader organization via mentorship, code review, knowledge sharing, etc.
Manage project priorities, estimates, and deliverables

What You'll Need

At least three years of direct experience building commercial web applications in JavaScript/TypeScript
At least two years of that experience working directly on web UIs in a modern framework
At least one domain of interest to develop deep expertise (e.g., web performance, design systems, framework knowledge, etc.)
Some interest in product design
Kind and efficient communication skills for both technical and non-technical audiences
Ability to deeply understand product and technical requirements

Technologies & Tools We Use

Development: TypeScript, React, Next.js, Tailwind, LangGraph, AI SDK, Drizzle
