A Software Engineer may focus on specific areas of software design and implementation, with less emphasis on full stack expertise. The roles overlap in skills and industry usage, but the senior developer typically has broader responsibilities and experience in full stack development.

What are the key skills and qualifications needed to thrive as a Senior Full Stack Software Developer, and why are they important?

A Senior Full Stack Software Developer needs advanced proficiency in both front-end and back-end programming languages, strong problem-solving skills, and several years of relevant software development experience. Familiarity with frameworks like React or Angular, back-end technologies such as Node.js or Django, and experience with cloud platforms, CI/CD tools, and version control systems like Git are typically required. Excellent communication, teamwork, and leadership abilities help developers collaborate effectively and mentor junior team members. These skills are crucial for designing robust, scalable applications and leading complex projects to successful completion.

What is a Senior Full Stack Software Developer?

A Senior Full Stack Software Developer is an experienced professional who designs, develops, and maintains both the front-end and back-end components of web applications. They are proficient in multiple programming languages and frameworks, enabling them to work on the entire technology stack, from databases and servers to user interfaces. In addition to coding, they often lead projects, mentor junior developers, and help architect scalable solutions that meet business needs. Their role requires strong problem-solving skills, a deep understanding of software development best practices, and the ability to collaborate with cross-functional teams.

What types of projects and technologies can a Senior Full Stack Software Developer expect to work on, and how does the team typically collaborate?

Collaboration is highly cross-functional—you’ll regularly coordinate with product managers, UX/UI designers, QA engineers, and other developers through agile methodologies, code reviews, and sprint planning sessions. This role offers opportunities to mentor junior developers, influence architectural decisions, and contribute to continuous process improvement.

Job description

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 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.
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.
  • Self-sufficiently manage project priorities, estimates, and deliverables
What You'll Need:
  • 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
Technologies & Tools We Use:
  • Development : TypeScript, React, Next.js, Tailwind, LangGraph, AI SDK, Drizzle
  • Ops : Git, GitHub, Amazon EKS, AWS, Sentry, Langfuse, Prometheus
At Kensho, we pride ourselves on providing top-of-market benefits, including:
  • Medical, Dental, and Vision insurance
  • 100% company paid premiums
  • Unlimited Paid Time Off
  • 26 weeks of 100% paid Parental Leave (paternity and maternity)
  • 401(k) plan with 6% employer matching
  • Generous company matching on donations to non-profit charities
  • Up to $20,000 tuition assistance toward degree programs, plus up to $4,000/year for ongoing professional education such as industry conferences
  • Plentiful snacks, drinks, and regularly catered lunches
  • Dog-friendly office (CAM office)
  • Bike sharing program memberships
  • Compassion leave and elder care leave
  • Mentoring and additional learning opportunities
  • Opportunity to expand professional network and participate in conferences and events
