đź“‹ Description

  • • Embark on a pivotal role as a Senior Fullstack Engineer within SoSafe GmbH's dynamic Simulation Team, contributing to our ambitious mission to become Europe's leading human risk management provider. You will be instrumental in developing, monitoring, and maintaining highly scalable and reliable fullstack software systems, leveraging a modern tech stack centered around Typescript, React, and Node.js, all deployed within a robust AWS environment.
  • • Your responsibilities will extend to actively participating in the architectural design of complex web applications, ensuring that our platform is not only functional but also built for future growth and resilience. This involves deep collaboration with both the platform and frontend engineering teams to guarantee seamless integration of services and features, fostering a cohesive and efficient development process.
  • • A key aspect of this senior position involves mentoring and coaching less experienced developers. You will share your expertise, guide them through technical challenges, and foster a culture of continuous learning and improvement within the team. Your leadership will be crucial in elevating the overall technical capabilities of the Simulation Team.
  • • You will be at the forefront of innovation, working on features that directly impact our award-winning awareness platform. This platform is designed to trigger behavioral change by providing effective and engaging training and simulations on cybersecurity and data protection, a critical area given that cybercrime is costing the world over $10 trillion annually and growing by 15% per annum. You will be part of the solution to this growing global problem.
  • • The role demands a strong understanding of relational databases, with a preference for Aurora PostgreSQL, and a solid grasp of RESTful API design principles and microservices architecture. Familiarity with the AWS ecosystem is essential for deploying and managing our cloud-native applications.
  • • You will also be responsible for ensuring the health and performance of our systems by utilizing monitoring tools such as Sentry, Datadog, and Grafana. Proactive identification and resolution of issues will be a core part of your daily activities, ensuring a stable and high-performing user experience.
  • • We are seeking individuals who thrive in environments characterized by scale-up operations and rapid change, ideally within SaaS businesses. Experience with Agile/Scrum development methodologies is expected, enabling you to adapt quickly to evolving project requirements and deliver value iteratively.
  • • Your ability to think analytically and solve complex problems will be highly valued. You will contribute to technical discussions, propose innovative solutions, and drive technical excellence across the team. This role offers a unique opportunity to make a significant impact in the cybersecurity space, working with a passionate team dedicated to making the digital world safer.
  • • You will be a key contributor to the continuous improvement of our development processes, code quality, and overall system architecture. This includes participating in code reviews, advocating for best practices, and staying abreast of emerging technologies and trends in fullstack development.
  • • The collaborative nature of this role means you'll be working closely with product managers, designers, and other stakeholders to translate business requirements into robust technical solutions. Your input will be vital in shaping the future of our product and ensuring it meets the needs of our growing customer base.
  • • By joining SoSafe, you are not just taking on a job; you are becoming part of a purpose-driven organization that is making a tangible difference in cybersecurity. You will have the opportunity to grow your career alongside a rapidly expanding company, backed by leading VCs, and contribute to a culture that values innovation, diversity, and collaboration.
