As our platform continues to scale, security becomes a core product capability rather than a separate function. We're looking for a Product Security Engineer who can partner directly with engineering teams to build secure systems from the ground up.
This is a highly technical, hands-on role where you'll improve the security of our applications, cloud infrastructure, APIs, and development lifecycle.
Responsibilities
Day-to-day scope for the Product Security Engineer as described in the posting:
Application Security
- Review application architecture and new product features from a security perspective.
- Identify security vulnerabilities across backend services, APIs, mobile applications, and web platforms.
- Perform threat modeling and security design reviews.
- Support internal and external penetration testing activities.
Secure Development
- Build and improve Secure SDLC across engineering teams.
- Integrate security tooling into CI/CD pipelines.
- Improve developer security practices and provide technical guidance.
- Help engineering teams remediate vulnerabilities.
Cloud & Infrastructure Security
- Improve the security posture of our cloud infrastructure.
- Secure Kubernetes environments, IAM policies, secrets management, and infrastructure components.
- Implement security monitoring and hardening best practices.
- Work closely with Platform and DevOps teams.
Security Automation
- Deploy and maintain SAST, DAST, dependency scanning, container scanning, and secret detection.
- Automate security checks and developer workflows.
- Continuously improve security visibility across the engineering organization.
- 4+ years of experience in Product Security, Application Security, Software Engineering, or Security Engineering.
- Strong software engineering background.
- Experience securing backend systems, REST APIs, and microservices.
- Experience with cloud platforms (AWS, GCP, or Azure).
- Strong understanding of Kubernetes, Docker, networking, and infrastructure security.
- Experience with Secure SDLC and security automation.
- Hands-on experience with SAST, DAST, dependency scanning, and secrets management.
- Understanding of OWASP Top 10, common attack vectors, and secure coding practices.
- Ability to work closely with software engineers and influence technical decisions.
- Fluent English.
Nice to have
Additional experience noted as a plus:
- Mobile application security experience.
- Experience in fintech, crypto, payments, or blockchain.
- Offensive security or penetration testing experience.
- Security certifications are a plus but not required.
- Professional growth: support for courses, conferences, and English learning (up to 100% coverage).
- Work-life fit: remote or hybrid format with flexible hours across international teams.
- Paid leave: up to 20 vacation days + 8 company holidays + 5 personal days per year
- Recognition programs: structured performance reviews and team awards.
- Team culture: retreats in international locations (for example, company apartments in Cyprus).
Build a standout application
For the Product Security Engineer at GoMining, reviewers look for concise evidence over buzzwords. Mirror the language of the posting sparingly, quantify support or delivery outcomes, and show how you handled ambiguity, time-zone collaboration and user empathy. Keep your resume to impact, keep your cover note to one page, and link to artifacts — tickets resolved, docs shipped, dashboards owned — that prove you can operate in a fast-moving Web3 team. Prepare to discuss a time you turned a confusing user report into a clear fix and how you measure quality in support and operations.
Web3 hiring values reliability: on-time follow-through, clear writing, and a track record of improving runbooks and tooling. Treat the application as a work sample. For interviews, be ready to walk through how you prioritize across time zones, handle a difficult user, and decide when to escalate versus resolve directly. Show how you document decisions so the next teammate benefits.
In a distributed Web3 org, trust builds through written clarity. Use the cover note to demonstrate it. Add links to public work, keep formatting scannable, and close with a clear ask. Hiring managers skim — make impact obvious in the first half-page.
Career growth in Web3 rewards continuous learning. Follow protocol changelogs, practice with testnets, and contribute to open issues. Small, consistent contributions compound into credibility more than one-off credentials.
