Security Engineer performs hands-on coding, incident response, threat-hunting, and policy development to secure backend systems and infrastructure.
About Eneba
At Eneba, weâre building an open, safe and sustainable marketplace for the gamers of today and tomorrow. Our marketplace supports close to 20m+ active users (and growing fast!), provides a level of trust, safety and market accessibility unparalleled to none. Weâre proud of what weâve accomplished in such a short time and look forward to sharing this journey with you. Join us as we continue to scale, diversify our portfolio, and grow with the evolving community of gamers.
You will join a growing security team where you can take meaningful ownership of the practices and policies you help develop. You will work closely with backend engineering and other departments to integrate practical security requirements across the company.
As a Security Engineer, youâll cover a broad range of operational and strategic security work rather than a single narrow specialty. In your first few months, youâll focus on learning Enebaâs tech stack and understanding how our services and systems fit together. That foundation is essential before you can secure those systems effectively.
Day-to-day, you can expect to:
Hands-on coding and security implementation work make up the largest part of the role today, alongside incident response and threat-hunting responsibilities.
Review and triage security submissions and incident reports.
Evaluate and respond to bug bounty reports, including remediation follow-through
Build, operate, and improve incident response and remediation processes.
Write and maintain security policies and documentation.
Communicate security requirements and risks clearly to non-technical departments
Review application monitoring and logs to catch and investigate anomalies
Support access governance and permission-management processes.
The tech stack is the same one our backend teams work with. Youâre not expected to know all of it on day one, but you should expect to be learning how to use most of it within your first 3 months, and youâll also be working across other languages and systems used throughout the company as your role demands.
Code
PHP/Symfony
Golang
GraphQL
gRPC
CQRS, commands via saga/temporal, queries via GraphQL
Microservices architecture
Service orchestration withSaga /temporal.io
Databases
InfluxDB
Redis
ElasticSearch
MariaDB
MySQL
Infrastructure
Kubernetes
Helm
AWS
Terraform
Prometheus
Strong written and verbal communication skills - this is our highest priority, since youâll regularly need to explain technical risk to non-technical audiences
Solid PHP knowledge
Security knowledge, or a clearly demonstrated interest in security (bug bounties, CTFs, security blogs, following the security community)
A background in IT, backend engineering, or a related technical field
Self-sufficiency - comfort taking ownership of tasks and making progress without constant guidance.
Ownership mentality and strong problem-solving skills
Openness to learning and working across multiple systems, languages, and technologies rather than staying in one lane
Nice to have
Experience with monitoring tools and application monitoring
Familiarity with the OWASP Top 10
âŹ58,000 - âŹ69,000 a year
