Onapsis eliminates this blind spot by providing cybersecurity solutions dedicated to business-critical applications. Whether running on premises, in the cloud, or in a hybrid environment, Onapsis helps nearly 30% of the Forbes Global 100 understand the threats and risks across their SAP and Oracle landscapes.
We are looking for self-motivated and enthusiastic Software Engineer in Test with Python and JavaScript who want to impact cybersecurity by continuing to advance, maintain, and enhance our platform features in Threat Detection & Response, Vulnerability Management, and Compliance Automation.

Working with leadership, product management, engineering, and the Onapsis research team. You will design, implement, and execute test procedures to ensure software features work as intended. Focused on automation and advancing automation capabilities, you will also design, build, and use test automation and build automation to ensure our software always fulfills business solution requirements to protect our customers. Work collaboratively as part of a software engineer team aligned with cybersecurity researchers and product managers to iterate toward product definition and realization. Additionally, you will be working with the Architecture team to take the platform to the next level of maturity in terms of technologies, quality, and architecture design while advancing our quality engineering processes to deliver high-quality products and services.
Responsibilities:
- Design and develop user-facing features and interfaces using modern front-end technologies such as HTML5, CSS3, and JavaScript frameworks (React).
- Ensure the technical feasibility of UI/UX designs and optimize applications for maximum speed and scalability.
- Conduct thorough testing and debugging of front-end components to ensure high performance and cross-browser compatibility.
- Stay updated on emerging trends and best practices in front-end development, incorporating new technologies and techniques as appropriate.
- Utilize Python to build backend services, APIs, and scripting solutions to support front-end functionality and enhance application features.
- Work alongside senior developers to contribute to the design and implementation of Python-based solutions, following best practices and coding standards.
- Participate in code reviews and provide constructive feedback to improve code quality and maintainability.
- Continuously expand your knowledge and skills in Python development through self-learning and mentorship opportunities.
- Conduct thorough testing of both front-end and backend components, identifying and addressing any issues or bugs in a timely manner.
