Job description

Senior Full Stack Developer

We are seeking a highly motivated Senior Full Stack Developer to join our dynamic team and help expand our innovative product portfolio. Our mission is to seamlessly connect people and spaces through an open platform that includes cloud-based video intercoms, wireless locks, and third-party access control systems. The ideal candidate will possess a robust background in full-stack web development, proficiency in modern frameworks and best practices, and a passion for creating cutting-edge user experiences. In this role, you will design, develop, and optimize sophisticated web applications, mentor junior developers, and collaborate with cross-functional teams to ensure the highest standards of performance, reliability, and security.

Your Responsibilities
  • Coordinate with product and engineering managers to align development with business goals.
  • Architect, design, and implement efficient, scalable, and responsive web applications using modern frameworks and technologies across teams (e.g. design, platform).
  • Monitor relevant metrics and identify areas for improvement, e.g. according to web performance best practices.
  • Address bugs and performance issues through automated unit, integration, and end-to-end testing.
  • Address vulnerabilities, apply updates, and maintain security documentation proactively.
  • Mentor junior developers, interns, conduct code reviews, and offer guidance on complex tasks.
Your Qualifications
  • 6+ years of progressive experience in web development, including front-end and back-end integration.
  • Bachelor's degree in Computer Science, Information Technology, or a related field (preferred).
  • Expertise in web technologies (HTML, CSS) and languages, frameworks and libraries (e.g. TypeScript, React, React Query, Tailwind).
  • Strong full-stack capabilities, including server-side development and API integration.
  • Proficiency in Node.js and its http frameworks like express/fastify/tRPC.
  • Experience with relational database systems (e.g., PostgreSQL, MySQL)
  • Familiarity with cloud platforms (e.g., AWS, Azure, or GCP) and containerization technologies (e.g., Docker).
  • Proficiency in version control systems (Git) and agile collaboration (e.g., GitHub, Jira, or similar).
  • Proven track record of performance optimization, including load time improvements and resource management.
  • Experience with automated testing frameworks (Cypress/Playwright) and debugging complex issues across the full stack.
  • Outstanding communication skills, with the ability to articulate technical concepts to both technical and non-technical stakeholders.
  • Excellent organizational and project management abilities, ensuring efficient task prioritization and timely delivery.
  • Commitment to continuous learning and staying current with emerging web development trends and best practices.
Your Process With Us
  • Application: Submit your application through our online form and include a link to your LinkedIn profile.
  • CV Screening: Our recruiting team will review your resume to assess your background, skills, and fit for the role.
  • Technical test task: You'll receive a short, take-home technical assignment designed to simulate the kinds of problems you'll tackle on the job.
  • Technical interview: Meet one-on-one (via video call) with a member of our support team to walk through your test task, discuss your approach, and dive deeper into your technical experience.
  • Culture interview: Have a conversation with cross-functional team members to learn more about our values, work style, and company culture—and for us to learn more about what motivates you.
  • Offer: If it's a mutual fit, we'll extend a formal offer and welcome you to the Kisi team.

After successful interviews and the job offer is signed, we will conduct a background check.
