ABOUT ENEBA
At Eneba, we’re 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. We’re proud of what we’ve 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.
ABOUT YOUR TEAM
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.
ABOUT THE ROLE
As a Security Engineer, you'll cover a broad range of operational and strategic security work rather than a single narrow specialty. In your first few months, you'll focus on learning Eneba's 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.
ABOUT THE TECH
The tech stack is the same one our backend teams work with. You're 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 you'll also be working across other languages and systems used throughout the company as your role demands.

An overview of this role
As a Backend Engineer on the Plan: Spec-Driven Development team, you'll help build GitLab's intent-to-code loop: agentic workflows that turn a stated intent into a refined work item, an implementation plan, and verified, mergeable code. You'll own early-stage backend work across the flows, application programming interfaces, data models, and evaluation systems behind this experience, using Ruby on Rails, Python, PostgreSQL, GitLab Duo Agent Platform, large language model application programming interfaces, and an artificial intelligence gateway.
You'll join a small, distributed team working on one of GitLab's highest-visibility product bets, collaborating with design partners toward a public beta. In your first year, you'll lead major features from an unclear problem through release, help shape scope with product and users, mentor other engineers, and influence technical decisions across agent workflows and evaluation methods.
What you’ll do
Lead backend features from early product discussions through technical design, implementation, rollout, and post-launch learning.
Build the flows, application programming interfaces, and data models behind agent-generated work items, implementation plans, durable specifications, and mergeable code.
Develop evaluation and benchmarking systems that measure workflow quality, token cost, and success rate.
Use Ruby on Rails and Python to build reliable production systems, with PostgreSQL, GraphQL, representational state transfer, GitLab Duo Agent Platform, large language model application programming interfaces, and an artificial intelligence gateway.
Collaborate directly with product, design, engineers, design partners, and users to shape scope and make practical trade-offs.
Coordinate multi-person projects across the team and communicate decisions clearly in GitLab's asynchronous, all-remote environment.
Mentor other engineers and contribute to technical direction across the Plan group and related artificial intelligence initiatives.
Work in short iterations, share progress through demos, and use results and user feedback to guide what comes next.
Take part in on-call or operational support where your team’s ownership model requires it.
What you’ll bring
Strong Ruby on Rails experience in a large production codebase and production experience with Python.
Experience driving substantial projects with several engineers over multiple months, with clear user or business outcomes.
A product mindset and experience owning features end to end, including shaping scope, making trade-offs, engaging with users, and learning from adoption after launch.
A full stack background with a current focus on backend engineering, plus the ability to read modern frontend code and design effective APIs.
Strong application programming interface design and structured query language fundamentals.
Experience exploring artificial intelligence-assisted development.
The ability to work independently, collaborate across functions and regions, and support others through technical leadership and mentoring. Experience with GraphQL, PostgreSQL performance at scale, or building and evaluating large language model or agent systems is helpful but not required.
We welcome candidates with different backgrounds and transferable experience. If you're excited about the role but don't meet every qualification, we encourage you to apply.
About the team
We are a team of four engineers, with two backend and two frontend engineers across Canada and Europe. You'll work in an all-remote, async-first environment with weekly sync calls, retrospectives, demos, and short iterations.

Build and improve agentic flows and their reusable parts with LangChain and LangGraph, including the Flow Registry.
Work with Product Management, UX, frontend, backend and AI specialists to refine requirements and ship improvements in small iterations.
Design, implement and review APIs (including GraphQL and REST) and the backend logic behind them, with reliable, scalable and clear contracts for clients such as the GitLab monolith, IDE extensions and Duo CLI.
Improve and extend automated testing (pytest and other frameworks), including evaluations of agent and flow behavior, to strengthen quality and give developers faster feedback.
Share standards, patterns and learnings with other engineers to raise the bar for responsible AI integration and evidence-driven engineering.
Join Tier 2
on-call rotations
to troubleshoot production issues, contribute to root cause analysis, and improve observability and resiliency.
Keep an eye on the competitive landscape to help keep GitLab's agent platform best-in-class as more work becomes agentic.
Take part in on-call or operational support where your team’s ownership model requires it.
What you'll bring
Experience building and maintaining production Python backend applications, including APIs, asynchronous or background processing, and data models.
Experience with LLM application frameworks such as LangGraph, or designing and shipping AI-powered backend features or harnesses.
Skill in designing or extending APIs (REST, GraphQL or gRPC) with attention to scalability, maintainability and backward compatibility.
Comfort working across the stack in a mature codebase. Familiarity with Ruby on Rails and/or JavaScript and Vue is a plus.
Experience finding and fixing performance bottlenecks in applications.
Clear written and verbal communication, including technical proposals and documentation, in a remote, async, cross-functional team.
Openness to learning and to applying skills from related technologies or fields.
About the team
The
Agent Foundations stage
builds the foundations for GitLab's agentic AI experiences. We provide the platform, catalog and execution features that help teams deliver resilient agents and flows to customers. The stage has three groups: Agent Developer, AI Catalog and Agent Execution. Between them, they own the GitLab Duo Developer foundational flow and the Flow Registry; the AI Catalog, including custom agents, custom flows and external agent integrations; and agent execution, agent tools and agent observability.
Our engineers work async-first across EMEA, AMER, and India timezones. We work with teams across AI engineering and the rest of GitLab so the Duo Agent Platform can power many of GitLab's AI features.

An overview of this role
As a Backend Engineer on the Plan: Spec-Driven Development team, you'll help build GitLab's intent-to-code loop: agentic workflows that turn a stated intent into a refined work item, an implementation plan, and verified, mergeable code. You'll own early-stage backend work across the flows, application programming interfaces, data models, and evaluation systems behind this experience, using Ruby on Rails, Python, PostgreSQL, GitLab Duo Agent Platform, large language model application programming interfaces, and an artificial intelligence gateway.
You'll join a small, distributed team working on one of GitLab's highest-visibility product bets, collaborating with design partners toward a public beta. In your first year, you'll lead major features from an unclear problem through release, help shape scope with product and users, mentor other engineers, and influence technical decisions across agent workflows and evaluation methods.
What you’ll do
Lead backend features from early product discussions through technical design, implementation, rollout, and post-launch learning.
Build the flows, application programming interfaces, and data models behind agent-generated work items, implementation plans, durable specifications, and mergeable code.
Develop evaluation and benchmarking systems that measure workflow quality, token cost, and success rate.
Use Ruby on Rails and Python to build reliable production systems, with PostgreSQL, GraphQL, representational state transfer, GitLab Duo Agent Platform, large language model application programming interfaces, and an artificial intelligence gateway.
Collaborate directly with product, design, engineers, design partners, and users to shape scope and make practical trade-offs.
Coordinate multi-person projects across the team and communicate decisions clearly in GitLab's asynchronous, all-remote environment.
Mentor other engineers and contribute to technical direction across the Plan group and related artificial intelligence initiatives.
Work in short iterations, share progress through demos, and use results and user feedback to guide what comes next.
Take part in on-call or operational support where your team’s ownership model requires it.
What you’ll bring
Strong Ruby on Rails experience in a large production codebase and production experience with Python.
Experience driving substantial projects with several engineers over multiple months, with clear user or business outcomes.
A product mindset and experience owning features end to end, including shaping scope, making trade-offs, engaging with users, and learning from adoption after launch.
A full stack background with a current focus on backend engineering, plus the ability to read modern frontend code and design effective APIs.
Strong application programming interface design and structured query language fundamentals.
Experience exploring artificial intelligence-assisted development.
The ability to work independently, collaborate across functions and regions, and support others through technical leadership and mentoring. Experience with GraphQL, PostgreSQL performance at scale, or building and evaluating large language model or agent systems is helpful but not required.
We welcome candidates with different backgrounds and transferable experience. If you're excited about the role but don't meet every qualification, we encourage you to apply.
About the team
We are a team of four engineers, with two backend and two frontend engineers across Canada and Europe. You'll work in an all-remote, async-first environment with weekly sync calls, retrospectives, demos, and short iterations. This is early-stage work with broad ownership, space for creativity, and a fast pace. For more about our team and its work, see
