Job Duties and Responsibilities

Are you an energetic and talented Senior Full Stack Developer who loves tackling complex challenges? Do you thrive in a fast-paced startup environment and want to be part of an innovative team? If so, we have an exciting opportunity for you to join our growing startup.

At Lastwall, we're revolutionizing the cybersecurity industry and seeking a skilled Senior Full Stack Developer with a passion for cutting-edge technologies. As a senior level resource, you'll play a vital role in developing and maintaining our next-generation web applications.

As part of a small, high-impact team, you’ll often be working in areas with incomplete specifications or shifting priorities. We value people who take initiative, operate independently, and bring structure to ambiguity when needed.

While this is a full stack role, it is backend-focused, with an emphasis on building scalable APIs, designing robust data models, and ensuring high performance in a Rust and Postgres environment. Frontend work using Angular and TypeScript may occur, but backend architecture and implementation will be the core focus.

• Completing well groomed tickets independently
• Collaborating with stakeholders to gather requirements and assisting in estimating timelines.
• Ensuring timely delivery of high quality solutions
• Conducting research on relevant product and feature based solutions
• Anticipating potential stack roadblocks and provide well thought out and researched solutions
• Architecting and building backend frameworks, while also contributing to front-end structure as needed
• Developing user-friendly web applications using TypeScript, Rust, Angular, and Postgres.
• Ensure code quality through peer reviews and contribute to peer testing efforts.
• Writing clean and maintainable code
• Writing unit and integration tests with good test coverage
• Utilize your knowledge of cyber security best practices, including familiarity with OWASP Top 10, to implement secure coding practices.
• Embrace an agile methodology, participating in sprint planning, and daily stand-ups
• Enhance the scalability and performance of our applications while maintaining a strong focus on user experience.
• Provide technical mentorship and support to peers, and help shape best practices across the frontend team
• Stay up-to-date with industry trends and emerging technologies to drive innovation and efficiency.
