Senior Application Security Engineer

At Bumble the security of our customers is a top priority. As an application security engineer at Bumble, you should be mission-focused on protecting our customers’ data by securing our company’s applications and products. 
You will architect, build, and support the security of Bumble's applications and products, protecting millions of users’ ability to form meaningful connections. With an attacker’s mindset, you will proactively identify potential attack vectors, while applying an engineering mindset to problem-solving—crafting creative solutions that reduce friction and enhance security through context-aware and automation-driven approaches. You thrive on prototyping, experimentation, and mentoring others to develop their technical security skills.
In this role, you will work closely with our engineering and leadership teams to identify and remediate vulnerabilities, establish strategic security best practices, provide security consulting and review services to up level the security maturity levels of our application and products. You will be able to navigate through high levels of ambiguities and be able to make independent judgement to help stakeholders thoroughly understand the security risks and make well informed decisions.

• Collaborate with engineering teams to embed security best practices and enforce security at every stage of the SDLC.
• Conduct risk assessments and threat modelling exercises to identify potential vulnerabilities and prioritise security measures based on impact.
• Collaborate with engineers to design secure application architectures, identify potential risks, and recommend security controls.
• Identify and prioritise vulnerabilities, driving remediation efforts and offering mitigation strategies to engineering teams.
• Train engineering teams in secure practices and promote a security-first mindset across the organisation.
• Keep up with the latest security trends, threats, and technologies, updating practices as needed to address evolving risks.
• Mentor and develop the technical security knowledge of junior team members and colleagues who show interest in learning security.
