What does a Sr Full Stack Web Developer do?

A Sr Full Stack Web Developer is responsible for designing, building, and maintaining both the front-end (client-side) and back-end (server-side) components of web applications. They work with various programming languages, frameworks, and databases to create seamless and efficient user experiences. In addition to coding, they often lead technical projects, mentor junior developers, and help shape the overall architecture of web solutions. Their role requires a deep understanding of both user interface design and server-side logic, ensuring that all parts of a web application function together smoothly.

What are the key skills and qualifications needed to thrive as a Sr Full Stack Web Developer?

To thrive as a Sr Full Stack Web Developer, you need advanced proficiency in both front-end (e.g., HTML, CSS, JavaScript frameworks) and back-end (e.g., Node.js, Python, databases) development, typically supported by a degree in computer science or related experience. Familiarity with tools such as Git, cloud platforms (AWS, Azure), RESTful APIs, and relevant certifications like AWS Certified Developer are commonly required. Strong problem-solving skills, effective communication, and the ability to mentor junior developers are essential soft skills for this role. These competencies ensure you can deliver robust, scalable solutions while collaborating efficiently within multidisciplinary teams.

How does a Sr Full Stack Web Developer typically collaborate with cross-functional teams during a project lifecycle?

As a Sr Full Stack Web Developer, you will frequently collaborate with UX/UI designers, product managers, QA engineers, and sometimes DevOps specialists throughout a project's lifecycle. You may participate in sprint planning, code reviews, and daily stand-ups, ensuring alignment on project goals and technical requirements. Effective communication is key, as you'll often translate business needs into technical solutions and provide guidance to junior developers. This collaborative environment supports the delivery of robust, user-friendly web applications and fosters professional growth through shared knowledge.

Job description

Nebulock is an agentic threat hunting platform that autonomously surfaces behaviors, not just IOCs, from various data sources. Nebulock acts like a teammate: a 24/7 AI threat hunter that investigates hypotheses, reasons through telemetry, and learns from an environment. Today, threat hunting is broken. Security teams spend weeks chasing alerts, writing detections by hand, and manually validating findings often just to confirm what their existing tools already flagged. Meanwhile, attackers exploit credentials, move laterally, and operate in silence. Nebulock flips the model. We continuously and autonomously hunt across endpoint, identity, and cloud telemetry identifying the subtle behavioral signals that point to credential misuse, lateral movement, insider threats, and post‑access activity. Then we turn those hunts into hardened, behavior‑based detections automatically.
