Web3 Security Engineer
Job description
About the role
The Web3 Security Engineer embeds with engineering squads to safeguard smart contracts across development and production.
Security professionals protect systems, data, and users. They review code, run tests, monitor threats, and respond to incidents. The field spans application security, infrastructure security, and governance. Security work is careful, evidence based, and constantly evolving. Security teams work in a landscape of constant change, with new threats and new rules every year. Most companies invest heavily in training and tooling for their teams.
Key facts
What you'll do
Security assessments drive the evaluation of products and infrastructure to identify vulnerabilities before launch. You conduct threat modeling, tabletop exercises, and code reviews while hunting for security weaknesses.
Smart contract monitoring ensures blockchain events are emitted sufficiently to support observability. You leverage monitoring platforms to maintain ongoing visibility into contract behavior.
Incident response runbooks are maintained and updated to guide handling and escalation.
Technology evaluation identifies and tests new security tools for internal adoption. You assess solutions to advance the security practices across the organization.
Security gap analysis uncovers weaknesses in smart contract architecture. You collaborate with engineering to close these gaps and improve the overall security posture.
Cross-functional collaboration with engineering teams clarifies requirements and integrates security into smart contract design. You work effectively with partners and respond quickly to needs.
Requirements
Solidity expertise is required with strong knowledge of the language and smart contract development patterns. You can audit Solidity code for correctness and security flaws.
Blockchain security experience includes hands-on work with blockchain and smart contract security tooling. Familiarity with blockchain monitoring solutions is required.
Bias for action describes an attitude of ownership and rapid execution. You are a top talent who is driven to learn and deliver results.
Clear communication in English enables effective collaboration across diverse teams. You listen actively and build trust with partners.
Analytical problem-solving supports identifying and resolving security issues. You apply strong analytical skills to complex challenges.
Practical notes
Typical interview steps
Security interviews usually include a technical assessment, a threat modeling exercise, and behavioral rounds. Candidates may be asked to review a code sample for vulnerabilities or design a secure system. Practical knowledge and clear risk communication are the core skills. Interviewers often ask how you triage and communicate risk. Showing calm judgment under pressure matters as much as technical depth.
Good to know
Blockchain security professionals commonly work with smart contract audit tools and monitoring platforms. Development teams often use AI assisted tools to accelerate security reviews. Security engineers build runbooks to standardize incident handling.
Questions to ask
Useful questions for the interview: what a typical week looks like, how work is assigned, what tools the team uses, and how feedback works. Asking how the role has changed recently and what the team wishes it had known when joining is also reasonable. Questions about the manager's priorities are especially valued.
Career growth
Security careers grow from analyst or engineer to senior, staff, and leadership roles. Specializations include cloud security, application security, and security operations. Certifications help early; demonstrated impact matters later. Security careers reward specialization and a track record of finding and fixing real issues. Written communication of risk is a core skill at senior levels.
