Role
Who you are
- 3 to 6+ years of experience as a software engineer
- Experience in a fast-growing startup or scale-up environment
- Meaningful contribution to a large web application, especially back-end
- Solid experience with back-end development (ideally Python)
- Comfortable with JavaScript or TypeScript
- Understanding of web-related security risks (or a strong motivation to learn)
- A fullstack & DevOps mindset
- Fluent in written and spoken English
- Hands-on experience with AI development tools and a genuine curiosity about their evolution
- Cares about the final product and the end user
- Gets things done with pragmatism
- Questions the status quo when necessary
- Communicates efficiently with others
- Knows how to deal with disagreements constructively
- If you don't meet every requirement but believe you'd be a great fit, we encourage you to apply and tell us why
What the job involves
- The Product & Engineering organization at CybelAngel is about 45-50 people, from product managers to support agents, from infrastructure experts to data scientists/ML engineers
- Teams are focused on building the web applications and underlying services used by our in-house security analysts, external partners, and clients to handle and remediate cybersecurity threats
- We are looking for a talented Software Engineer who will help CybelAngel build the next generation of those web applications using modern technologies, design principles — and an AI-first mindset
- The teams together share a wide functional scope which comprises dedicated web apps such as:
- Tools for investigating and remediating cybersecurity threats
- Dashboards to help our clients understand their exposure to risks
- APIs for partners to plug into our workflows
- Specialized panels to fine-tune our threat detection technologies
- Teams are able to decide and operate on the whole stack ranging from infrastructure to visual appearance, through data models, APIs and business logic, with guidance from more specialized teams when needed (e.g. SRE, Product Design)
- Join the Core Team, where you'll tackle a broad and impactful technical scope at the crossroads of all our engineering teams
- We're a backend-focused team, deeply immersed in building and maintaining Python APIs that power the products our customers rely on every day—from the APIs behind our frontends to the authorization and authentication systems that keep everything secure
- Made up of senior engineers with diverse areas of expertise, the team offers a rich environment to grow, collaborate, and make a real technical impact
- All software engineers routinely:
- Design, implement and deploy new product features
- Review and test code written by their teammates
- Monitor applications running in production
- Investigate incidents and fix bugs
- Take part in the daily life of their team
- Going further:
- More experienced engineers do their best to make their team better. More specifically, they:
- Inspire junior engineers by being exemplary
- Pair on difficult tasks with less-experienced engineers
- Improve practices to speed up development
- Identify major technical improvements to be pursued
- Promote attention to product quality
- AI in your daily work:
- AI is already part of how we build at CybelAngel — and we expect this to grow significantly. As an engineer here, you will:
- Use AI-assisted development tools (e.g. Claude, Cursor, or equivalent) as a genuine productivity lever, not just as an autocomplete
- Critically assess AI-generated code: you know when to trust it, when to push back, and how to review it rigorously
- Contribute to integrating AI/LLM capabilities into our products where relevant — whether that means calling an API, building a retrieval pipeline, or evaluating model outputs
- Share learnings with your team and help shape our collective practices around AI-assisted development
- Stay up to date with how AI tooling is evolving and bring relevant experiments to the table
- Stack:
- Front-end: VueJS/VueX, Vuetify, TypeScript
- Back-end: Python, Flask
- Databases: PostgreSQL, MongoDB, ElasticSearch
- Infrastructure: GCP, Kubernetes, Docker, Terraform, Gitlab CI, Datadog

- 30' — Call with Pierre, Recruiter, to make sure expectations from both ends have a good chance to match
- 45' — Call with Gauthier, Engineering Manager, to evaluate skills and culture fit
- 90' — Call with two teammates to explore and discuss a practical situation
- 30' — Call with Loïc, CTPO
Our take
Cybercrime is an ever-present threat for all organisations, both large and small. And certain sectors, such as healthcare, are especially vulnerable to data leaks. CybelAngel is a digital risk protection platform that uses its robust tech to scour each layer of the web for data leaks.
Its approach involves maximising encryption defences, monitoring all remote connections, and ensuring employees are aware of the risks. With an aim to provide a rapid scanning speed of under 24 hours, customers are able to monitor their own data and detect when it is exposed. This allows businesses to have ownership of their own data security.
Its definitely an attractive proposition, as the issue of data privacy continues to be a hot topic. In the evolving cyberthreat landscape, CyberAngel continues to meet new business requirements and improve efficiency as it expands its global ecosystem and develops new security solutions.
