Sidechain is a talent platform connecting you with vetted security engineers, smart contract auditors and DevSecOps engineers for crypto, fintech and AI companies, a faster alternative to a security recruiter or recruitment agency.
Security engineers protect systems, data and assets from attackers. In crypto and fintech, they audit smart contracts for vulnerabilities, secure payment infrastructure handling real money, implement authentication and access controls, build monitoring systems to detect anomalies, conduct penetration testing, and respond to security incidents.
Beyond finding vulnerabilities, they design secure architectures, implement security tooling and automation, define threat models, conduct security reviews during development, maintain compliance controls, and teach engineering teams to build more secure systems. The role demands both defensive thinking (hardening systems) and offensive thinking (attacking systems to find weaknesses).
In practice, security engineering spans smart contract auditing (formal verification, vulnerability research), application security (authentication, authorization, input validation), infrastructure security (cloud configuration, network controls, secrets management), DevSecOps (security automation, SAST/DAST tools), and security operations (monitoring, incident response, forensics). For crypto and fintech companies, security failures have immediate financial consequences.
Many teams hire for credentials over practical experience. Certifications like CISSP or CEH demonstrate foundational knowledge but don't prove someone can find vulnerabilities in your specific systems. Look for engineers who have discovered real bugs, shipped security improvements that withstood production attacks, and learned from actual incidents. The best security engineers have battle scars.
Another mistake is hiring specialists who can't collaborate with product teams. Security engineers must balance protection with usability and velocity. They need to understand business trade-offs, communicate risk without fearmongering, and design controls that developers will actually use. A brilliant security engineer who alienates the engineering team creates more risk than they mitigate.
Finally, many companies underestimate domain-specific expertise. Securing smart contracts is fundamentally different from securing web applications or cloud infrastructure. Each domain has unique attack vectors, tooling and patterns. For crypto and fintech companies, you need engineers who understand financial systems, blockchain security, and the regulatory constraints that shape your threat model.
We're a curated talent platform for security recruiting, not a job board. Instead of sorting through hundreds of candidates, you tell us your security requirements and we introduce a tailored shortlist of pre-vetted security engineers from our network of 1,500+ engineers.
Every engineer has been screened on their previous work and shipped projects, background and references, communication skills, and culture fit. We evaluate real security work: vulnerabilities they have discovered, security tooling they have built, incidents they have responded to, and systems they have hardened. Only the top 3% make it through our vetting process.
Most clients receive their shortlist within 5-7 days and complete a hire within 1-2 weeks. We support both contract and full-time placements. You pay nothing until you hire, with success-based fees and no retainers. If a hire leaves within 90 days for reasons unrelated to company performance, we provide a one-time replacement at no additional fee.
Look for engineers with deep knowledge of attack vectors, experience finding and fixing real vulnerabilities, and the ability to think adversarially. The best security engineers have worked on production systems handling sensitive data or high-value assets, understand both application and infrastructure security, can communicate risk to non-technical stakeholders, and balance security with velocity. Practical experience matters more than certifications.
Most clients receive a tailored shortlist within 5-7 days. Our network includes engineers with experience across smart contract auditing, application security, cloud infrastructure security and DevSecOps for crypto, fintech and AI companies, so we can move at your pace.
Both. Whether you need an engineer to audit smart contracts, build security tooling, implement DevSecOps, or join your team permanently, we support contract and full-time placements.
We back every placement. If a hire leaves within 90 days of their start date for reasons unrelated to company performance, we provide a one-time replacement at no additional fee.
Nothing until you hire. We charge a success-based fee only once you've made a placement. No upfront costs, no retainers.
Yes. Our network spans smart contract security, application security, cloud and infrastructure security, DevSecOps, and security operations. We can match you with engineers experienced in the specific domains your company needs.
