What is a senior full stack engineer?

Senior Full Stack Engineers are experienced software developers who are proficient in both front-end and back-end technologies. They design, build, and maintain complex web applications, overseeing the entire software development process from user interface to server-side logic and databases. In addition to coding, they often mentor junior developers, lead technical decisions, and ensure best practices are followed throughout the project lifecycle. Their broad skill set allows them to bridge the gap between different development teams and deliver cohesive, high-quality solutions.

How do senior full stack engineers balance hands-on coding with mentoring and leading team projects?

Senior Full Stack Engineers often split their time between developing complex features, reviewing code, and guiding junior team members. Alongside hands-on coding, they play a key role in architectural decisions, ensuring code quality, and fostering best practices across the team. Effective communication and delegation skills are crucial, as they frequently collaborate with product managers, designers, and other engineers to align technical solutions with business goals. This balance provides opportunities for leadership growth while keeping technical skills sharp.

What are the key skills and qualifications needed to thrive as a senior full stack engineer, and why are they important?

To thrive as a Senior Full Stack Engineer, you need deep proficiency in front-end and back-end development, strong problem-solving skills, and a solid foundation in computer science, often supported by a relevant degree or equivalent experience. Familiarity with frameworks like React or Angular, back-end technologies such as Node.js or Java, cloud services, and version control systems like Git is typically required, along with experience in CI/CD and testing tools. Excellent communication, leadership, and collaboration skills help you guide teams and coordinate across disciplines.

Job description

Okara is an AI CMO that runs a team of specialized agents across every organic and social channel that matters for growth — SEO, GEO, an AI writer, Reddit, Hacker News, X, and more on the way. Each of those agents is a real, shipped product used daily, by us and by customers, and we need engineers who can own a piece of that and move fast.


You'll work directly with the growth team who actually use these agents every day, which means an unusually fast feedback loop: you ship something, someone on the growth team uses it that afternoon, and you hear immediately if it's wrong.


  • Our tech stack is NextJs, React, Vercel, AWS, etc.
  • Build and ship features across our agents — SEO, GEO, AI writer, Reddit, X — end to end, not just the easy parts.
  • Own at least one agent within your first month: not just tickets assigned to you, an actual area where you're the go-to person.
  • Work directly with the people using what you build, and fix what's actually broken, not just what's in the backlog.
  • You can explain what you built and why, clearly enough that someone outside engineering understands the tradeoff you made.


To succeed here, you need to have built and shipped something real, start to finish, that actual users touched, a previous founding engineer role in a growing startup would be great. 


To apply, send us a link to something you built and shipped that you're proud of, and one sentence on what you'd do differently if you rebuilt it today.
