Victor Omojoye
Last position:
AI Training Engineer at Confidential AI Research Client
- Codebase Evaluation & Problem Design: Designed and stress-tested complex software engineering problems against large open-source Python codebases (including pandas), requiring deep context acquisition and architectural understanding to produce well-scoped, realistic problem statements aligned to strict correctness guidelines.
- Agent Failure Analysis: Assessed LLM coding agent solutions for correctness and completeness, identifying meaningful failures across edge case handling, dtype behaviour, and multi-column NaN propagation logic; documented findings with precision for downstream evaluation use.

About the role
Secure systems
Security engineers protect infrastructure, applications, and data against misuse and attack. They design controls, close gaps, and help teams build secure systems without slowing delivery.
- Review architecture and identify weak points
- Harden cloud, network, endpoint, and identity layers
- Define secure baselines and technical guardrails
- Support incident handling and recovery steps
Typical work
A freelance security engineer is often brought in for security reviews before a launch, cloud migration support, zero trust rollout, or a response to a finding from a penetration test. They may also help with DevSecOps, SIEM tuning, IAM cleanup, or secure configuration work across AWS, Azure, GCP, Linux, and common CI/CD tools.
Core skills
Strong security engineers combine technical depth with clear judgment. They need to understand how systems fail, how attackers move, and how to reduce risk without creating friction for product and operations teams.
- Network, application, and cloud security knowledge
- Identity and access management, logging, and monitoring
- Threat modeling, vulnerability management, and remediation planning
- Clear communication with engineering, IT, and compliance teams
Deliverables
Companies usually expect concrete outputs, not just advice. Good work leaves behind decisions, settings, and documents that teams can keep using after the engagement ends.
- Security assessments and risk findings
- Hardening plans and remediation tickets
- Policies, runbooks, and incident notes
- Secure design reviews for new systems or changes
Berlin context
In Berlin, security engineers often work with startups, scale-ups, SaaS teams, fintech firms, and product companies that need hands-on support without adding a permanent hire too early. Mixed English and German collaboration is common, especially in larger or regulated teams, and many assignments combine remote work with occasional on-site sessions.
What strong people do
The best security engineers are practical. They spot the real risk, explain it in plain language, and focus on changes teams can actually implement.
- Prioritize issues by impact, not by noise
- Work well with developers, ops, and compliance
- Balance speed, usability, and control
- Leave the team better prepared for the next issue
Frequently asked questions
Questions about Security Engineers? Start with the answers below.
A Security Engineer protects systems, applications, and data by finding weaknesses and helping teams fix them. In a freelance setup, the work often includes security reviews, hardening, access control design, monitoring improvements, and support during incidents or audits. The goal is to reduce risk in a way the team can maintain after the engagement ends.
Look for strong knowledge of cloud, network, application, and identity security, plus the ability to explain trade-offs clearly. A good security engineer should also be comfortable with logging, vulnerability management, incident response, and secure configuration work. Practical experience matters more than broad claims.
A penetration tester focuses on finding exploitable weaknesses, usually in a defined assessment. A Security Engineer takes the next step: they design, implement, and improve the controls that prevent those weaknesses from turning into incidents. The roles can overlap, but the day-to-day focus is different.
A freelance security engineer makes sense when you need focused expertise for a specific project, a backlog of security fixes, or temporary support during a change or incident. This is common when a team needs help fast but does not yet need a full-time specialist. It also works well when the internal team needs a second pair of hands for design reviews or hardening work.
Most of the work can be done remotely, especially reviews, documentation, threat modeling, and cloud or application security tasks. Some clients in Berlin prefer on-site time for workshops, access to sensitive environments, or close work with infrastructure teams. A strong freelancer should be comfortable with either setup.
Common tools include cloud security controls, SIEM platforms, vulnerability scanners, IAM systems, secret management tools, and infrastructure-as-code pipelines. The exact stack depends on the client, but many projects involve AWS, Azure, GCP, Linux, Kubernetes, and CI/CD systems. The best fit is someone who can work across the stack, not just in one tool.
Ask for examples of security problems they solved, how they prioritized them, and what changed after their work. A strong Security Engineer can describe concrete decisions, not just frameworks and acronyms. Good signs are clear thinking, realistic recommendations, and an ability to work with developers and operations teams without creating blockers.
Not exactly, but the titles often overlap in practice. An application security engineer usually focuses more on code, APIs, and software delivery, while a cloud security engineer leans into cloud controls, identity, and platform hardening. Many freelance security engineers cover both areas, especially in smaller teams or fast-moving product environments.
