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.

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.
• Develop backend services that connect AI capabilities with existing business systems.
• 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.

About the Role

We’re a lean product team developing a consumer commerce platform that combines real-time 3D interactions with the purchase of physical products. The product also includes a real-money wallet and operational workflows for order processing and fulfillment.

Our technology stack is built entirely around TypeScript. The engineering team is small and experienced, with engineers working closely with and reporting directly to the CTO, allowing for fast communication and decision-making.

We’re looking for a Senior Mobile Engineer to lead the development of a native mobile application for an existing consumer product with rich, real-time 3D interactions.

You’ll take ownership of the React Native application from initial architecture through production release on both iOS and Android. A major part of the role will be translating an existing interactive web experience into a smooth native product, including animations, gestures, and platform-specific functionality.

This is not a mobile-only position. Engineers are encouraged to own features end to end, including the supporting APIs, asynchronous processing, and database changes. The backend is built with Node.js and TypeScript, so experience working beyond the mobile layer is highly valued.

What You'll Do

• Design and develop the mobile application using React Native, Expo, and TypeScript, from initial setup through App Store and Google Play releases.
• Build high-quality animations and gesture-based interactions using tools such as Reanimated, Gesture Handler, and Skia, with a strong focus on smooth performance.
• Implement payment functionality, wallet-related experiences, and reliable synchronization between client-side state and backend financial records.
• Work with native functionality when required, including push notifications, secure storage, media playback, deep linking, and platform-specific payment integrations.
• Own features across the stack when needed: define API contracts, develop Fastify endpoints and background processes, implement the mobile experience, and add appropriate monitoring and instrumentation.
• Establish and maintain the mobile delivery process, including builds, signing, store submissions, OTA updates, and crash reporting using EAS, fastlane, or similar tooling.

What We're Looking For

• 7+ years of professional mobile development experience, including at least 3 years working with React Native applications released to production.
• Strong TypeScript skills and practical familiarity with Swift and/or Kotlin for debugging, understanding native issues, and implementing platform-specific functionality when necessary.
• Hands-on experience building complex mobile animations and gesture-driven interfaces.
• Understanding of mobile performance and the ability to create responsive, smooth user experiences.
• Practical backend knowledge, ideally including Node.js APIs, relational databases, and asynchronous processing or message queues.
• Ability to take ownership of features beyond the mobile interface and contribute to their server-side implementation is strongly preferred.
• Experience with payments, digital wallets, or other transaction-heavy consumer applications is a significant advantage.

Nice to Have

• Experience with mobile 3D technologies such as Three.js, react-three-fiber, SceneKit, or GPU-accelerated Skia.
• Experience handling complex video and media playback scenarios on mobile.
• Previous experience transforming an established web product into native iOS and Android applications while maintaining a consistent product experience.

Technology Stack: React Native · Expo · TypeScript · Reanimated · Gesture Handler · Skia · Node.js · Fastify · PostgreSQL · RabbitMQ · Zod · pnpm
