Senior DevSecOps Engineer

TinyFish • Ho Chi Minh City, CA

6d • $150,000 - $200,000 • Remote

About The Position

TinyFish is looking for a hands-on Senior DevSecOps Engineer to drive the execution of our security program across infrastructure and product engineering. You will own the day-to-day vulnerability management process, implement and automate security controls, and work with engineering teams to drive findings through remediation and verified closure. You will help translate security policies, compliance requirements, penetration-test findings, and identified risks into concrete engineering work. This is an individual-contributor role for someone who combines strong cloud and application-security fundamentals with a bias for execution. You will partner closely with Infrastructure, Engineering, Product, and company leadership. You will not be expected to single-handedly own every aspect of company security strategy, compliance, and risk acceptance.

Requirements

• 5+ years of hands-on experience in DevSecOps, cloud security, application security, security engineering, or a related role.
• Demonstrated experience building or operating a vulnerability-management program and driving findings through verified remediation.
• Strong knowledge of AWS security, including IAM, VPC networking, KMS, secrets management, logging, monitoring, and multi-account environments.
• Production experience with infrastructure as code, preferably Terraform.
• Experience securing CI/CD pipelines, preferably GitHub Actions, including identity, permissions, secrets, dependencies, and build artifacts.
• Practical experience with security tooling such as SAST, DAST, software-composition analysis, secret detection, container scanning, cloud-security posture management, and infrastructure-as-code scanning.
• Solid understanding of common application-security risks, secure coding practices, authentication and authorization patterns, and the OWASP Top 10.
• Experience reviewing technical designs, conducting threat models, and turning identified risks into actionable engineering recommendations.
• Experience supporting security incident response, root-cause analysis, and corrective-action tracking.
• Familiarity with SOC 2, ISO 27001, CIS Benchmarks, or similar security and compliance frameworks.
• Ability to automate security workflows using Python, Bash, or another scripting language.
• Strong written and verbal communication skills, including the ability to explain risk, priorities, and remediation requirements to both engineers and leadership.
• A pragmatic, risk-based approach and a strong bias toward measurable execution.

Nice To Haves

• Experience securing containerized or isolated workloads running on ECS, EKS, Kubernetes, or similar platforms.
• Experience with AWS Organizations, Control Tower, Security Hub, GuardDuty, AWS Config, CloudTrail, and IAM Identity Center.
• Experience securing distributed systems, public APIs, browser automation infrastructure, or systems that handle customer credentials and session data.
• Experience with SIEM, centralized security logging, and detection engineering.
• Experience automating compliance evidence collection or working with platforms such as Vanta.
• Experience coordinating penetration tests, red-team exercises, or customer security reviews.
• Security certifications such as CISSP, CISM, CCSP, AWS Security Specialty, or OSCP.

Responsibilities

• Own the vulnerability-management lifecycle across cloud infrastructure, application code, dependencies, containers, CI/CD systems, and production services.
• Establish repeatable processes for vulnerability discovery, triage, severity assessment, ownership, remediation SLAs, exceptions, verification, and reporting.
• Drive critical and high-severity findings through closure by partnering with service owners and escalating unresolved risks when necessary.
• Implement and maintain security controls across AWS, including IAM, networking, encryption, key management, secrets, logging, and workload isolation.
• Integrate security into the software-development lifecycle through practical guardrails such as SAST, DAST, dependency scanning, secret detection, container scanning, and infrastructure-as-code checks.
• Review security-sensitive designs and changes, perform threat modeling, and provide concrete recommendations to engineering teams.
• Improve security across public APIs, authentication and authorization, service-to-service communication, customer credentials, sensitive data, and software-supply-chain workflows.
• Coordinate third-party penetration tests and ensure findings are assigned, prioritized, remediated, and validated.
• Develop and maintain incident-response playbooks, participate in security incidents, facilitate tabletop exercises, and track corrective actions after incidents.
• Partner with Infrastructure and Observability teams to improve security logging, alerting, investigation workflows, and threat detection.
• Translate security policies and compliance controls into technical requirements, automated checks, and engineering work.
• Support SOC 2, ISO 27001, and other applicable assurance or regulatory initiatives through control implementation, evidence collection, and remediation of audit findings.
• Maintain clear reporting on security posture, vulnerability backlog, remediation performance, control coverage, and overdue risks.
• Create practical security guidance and documentation that helps engineers ship secure systems without unnecessary friction.

Benefits

• A high-impact role securing infrastructure and products at the core of an AI-powered web automation platform.
• Direct collaboration with Infrastructure, Product, and Engineering teams.
• Significant ownership and the ability to shape how security is implemented as TinyFish grows.
• A culture that values security, engineering quality, pragmatism, and accountability.
• A remote, distributed, and async-friendly work environment.
• Competitive compensation.
