The Role

The Security Engineer starts primarily in managed detection and response (MDR). On a normal day, the focus is detecting, investigating, and responding to security events. When project work requires additional engineering capacity, the engineer may be moved to support project work. When a significant cybersecurity incident occurs - whether for a client or internally - incident response becomes the priority and the broader security team participates as needed, regardless of normal schedules.

What You Will Do

• Investigate security alerts and events and determine whether activity is benign, suspicious, or requires escalation.
• Participate in detection and response operations, including guided containment and remediation decisions.
• Analyze security issues and recommend remediation or configuration changes; early in the role, changes are performed under guidance rather than independently.
• Work with logs and telemetry from endpoints, operating systems, networks, identity systems, cloud environments, and security platforms.
• Participate in client and internal cybersecurity incidents as part of the incident response team.
• Contribute to cybersecurity projects when assigned, learning the required technology as part of the project.
• Analyze internal and client security environments and make practical security recommendations under guidance.
• Grow into broader engineering responsibilities as your technical capability and interests develop.

Core Technical Foundation

We do not expect one person to know every security product. We care more about a strong technical foundation and the ability to understand how technologies fit together.

• Strong understanding of TCP/IP and computer networking. Networking knowledge is fundamental to this role.
• Intermediate knowledge of Windows and Linux administration and security, including how systems are secured and hardened without relying only on security tools.
• Solid understanding of core cybersecurity concepts, threats, controls, detection, and response.
• Working understanding of firewalls, network perimeter security, and modern security architecture concepts such as Zero Trust.
• Ability to reason through unfamiliar technical problems and learn new technologies quickly.
• Prior security operations, systems administration, network administration, or security engineering experience.
• Experience with any SIEM, EDR/XDR, log collection, or security monitoring platform.
• Active Directory, Microsoft Entra ID, identity management, or identity security experience.
• Cloud infrastructure or cloud security experience.
• Communication is in English – B1+ English level is required

Experience That Is a Plus

• Scripting or automation experience, such as PowerShell, Python, or similar technologies.
• Relevant technical certifications. Strong certifications in foundational technologies are valuable; we do not require a specific cybersecurity certification.

What Matters Most

• Responsibility and ownership – you take ownership of assigned work, follow it through to completion, communicate when something is blocked or unclear, and make sure important issues do not fall through the cracks.
• Curiosity - when something looks unusual, you want to understand why.
• Creativity - you can think beyond a checklist when an investigation does not follow an obvious path.
• Investigative mindset - you keep digging until the situation is understood and you are comfortable that the environment is secure.
• Attention to detail - small technical details can change the meaning of a security event.
• Learning ability - how quickly you comprehend new technologies and apply what you learn will directly influence how quickly you grow.
• Initiative and engagement - you are interested in the technology and the problem, not simply completing a queue of assigned tasks.

Training and Career Growth

This is a growth-oriented position. The initial concentration is detection and response. From there, the career path is not predetermined. We want to develop each engineer around both capability and passion. Someone with strength in scripting and automation may grow in that direction; another engineer may become stronger in infrastructure, cloud, incident response, security engineering, projects, or client-facing work. With sufficient growth, the path can lead to senior engineering, project leadership, client management, and potentially virtual CISO responsibilities.

Working Model

• Fully remote position.
• Aligned with U.S. working core hours (9 am to 5 pm EST/EDT).
• Detection and response is a 24x7 company function; over time, shifts may become more flexible based on team coverage and what works for the engineer.
• Significant cybersecurity incidents are treated as team events and may require participation outside the normal schedule.
• Client communication is not expected from day one; it can become part of the role as the engineer develops.
• No travel requirement.

Company: MTicket

 

About Us

MTicket is a technology company operating in the ticketing and live events industry. Our platforms support ticket sales, event management, payments, marketing, customer interactions, and various business operations.
We are actively developing our AI engineering direction to introduce intelligent automation and AI-powered functionality into our products and internal processes.
We're looking for a Senior Python AI Product Engineer who can turn ideas and business challenges into real, production-ready AI solutions.
This is a hands-on engineering role for someone who enjoys building products, experimenting with modern AI capabilities, and delivering working solutions.
We're not looking for someone who simply uses AI coding assistants. We need an engineer who has already built and launched AI-powered applications using LLM APIs.


 

What You'll Do

• Design, develop, and launch AI-powered applications and product features using Python and FastAPI.
• Integrate LLMs such as OpenAI, Anthropic, or similar providers through APIs.
• Build intelligent assistants, AI agents, and automated workflows to solve real business problems.

• Implement LLM tool/function calling, structured outputs, and multi-step workflows.
• Integrate third-party APIs, databases, and internal services.
• Work on AI solutions for ticketing, customer support, marketing, analytics, and operational processes.
• Collaborate with other engineers to build scalable and reliable AI-powered functionality.
• Take ownership of features from technical design and implementation to deployment and production support.
• Continuously improve AI functionality, response quality, performance, and API usage costs.

Our Tech Stack

• Backend: Python, FastAPI
• AI: LLM API integrations (OpenAI, Anthropic, or similar)
• Architecture: REST APIs, backend services, third-party integrations
• Development: Git

Our approach is pragmatic: we choose technologies based on the problem we're solving rather than relying on a specific AI framework.


 

What We're Looking For

• 3+ years of professional Python backend development experience.
• Solid commercial experience with FastAPI and backend API development.
• Proven experience building and launching AI-powered applications or product features in production.
• Hands-on experience integrating LLMs through APIs (OpenAI, Anthropic, Gemini, or similar).
• Experience developing AI assistants, AI agents, intelligent automation, or multi-step LLM workflows.
• Strong understanding of REST APIs, integrations, databases, and backend architecture.
• Experience implementing and maintaining production applications.
• Ability to independently design and deliver complete features.
• Understanding of AI application limitations, error handling, response validation, and API cost management.
• Strong problem-solving skills, ownership, and a product-oriented mindset.
• Ukrainian or Russian language proficiency at C1 level or higher.

Nice to Have

• Experience developing AI-first SaaS products or commercial AI applications.
• Hands-on experience with LangChain, LangGraph, or similar AI orchestration frameworks.
• Experience with RAG, embeddings, vector databases, or MCP.
• Experience building AI workflows involving multiple tools or external services.
• Familiarity with LLM evaluation, prompt optimization, and structured output validation.
• Experience in e-commerce, marketplaces, payments, ticketing, or marketing automation.
• Experience with cloud infrastructure, Docker, and asynchronous backend processing.
• Experience independently shipping products from idea to production.

What Makes a Great Candidate

We especially value engineers who have already built real AI applications and can confidently explain:
 

• What AI product or functionality they developed.
• What problem it solved and who used it.
• How LLM APIs were integrated into the application.
• What backend architecture and integrations they implemented.
• Which parts of the solution they personally owned.
• How they handled errors, unexpected AI responses, and production challenges.
• How the product was deployed and improved based on real-world usage.

We value practical engineering experience, independent thinking, and the ability to deliver useful products over knowledge of specific frameworks.


 

What We Offer

• The opportunity to build AI-powered products for an established ticketing and live events business.
• A growing AI engineering direction with significant room for innovation.
• Real business challenges where your work can have a measurable impact.
• Ownership of AI functionality from idea to production.
• Direct collaboration with engineering and business teams.
• Freedom to propose technical solutions and experiment with modern AI technologies.
• A fully remote working environment.
• A collaborative team and a practical, results-oriented engineering culture.

Interested?

If you've already built AI-powered products using Python and LLM APIs, enjoy solving real business problems, and want to see your solutions used in production, we'd love to hear from you.
When applying, please briefly describe an AI-powered product or feature you've personally built and launched. Feel free to share relevant GitHub repositories, product links, or examples of your work.
