From concept to launch, from license to live transactions — Skogos is where global fintech gets built, scaled, and delivered across multiple verticals: low-risk,  high-risk, crypto, and other payment industries.

We’re a global fintech holding focused on creating, launching, and scaling payment solutions worldwide. PSPs, processing platforms, merchant infrastructure — we don’t just advise, we build, operate, and optimize businesses from zero.

We’re entering a new phase: launching our Canadian entity, Skogos, in Toronto. The MSB license is already secured. We’re looking for a CEO with full ownership, including account access and signing authority, to turn structure into a revenue-generating, fully operational business.

Your Mission

Lead Skogos Canada from launch to scale — turning a licensed entity into a fully functioning, revenue-generating company. Own processes, delivery, partnerships, team, and results. This is hands-on leadership with full strategic authority and operational accountability.

What You Will Do

Company Launch & Operations

• Build internal processes: delivery, onboarding, compliance flows, reporting
• Coordinate legal, compliance, tech, and banking counterparts
• Ensure regulatory alignment and operational stability

Project & Delivery Management

• Oversee timelines, dependencies, risks, and operational execution
• Act as the main bridge between product, tech, compliance, and commercial teams
• Guarantee smooth onboarding and long-term merchant performance

Business & Strategic Execution

• Drive early commercial strategy, merchant acquisition, and expansion across multiple markets
• Support partnerships with banks, PSPs, providers, and vendors
• Identify bottlenecks, inefficiencies, and growth opportunities
• Gradually build and manage a local or distributed team

Leadership & Ownership

• Take full ownership of outcomes — not just tasks
• Signing authority & account access: contracts, bank accounts, and key operational documents
• Make strategic decisions: set priorities, allocate resources, and define execution plans

• Represent Skogos externally with partners, regulators, and at industry events

   

Ideal Candidate Profile

Experience & Background

• 5+ years in fintech, payments, PSPs, or multiple payment verticals
• Experience launching or scaling businesses, products, or entities
• Strong exposure to operations, delivery, or general management
• Experience working with regulated environments (MSB, EMI, PSP or banks)
• Canada / North America market experience is a strong advantage

Hard Skills

• Deep understanding of payment flows, onboarding, and compliance
• Strong project & delivery management skills
• Ability to work cross-functionally with tech, legal, compliance, and sales
• Structured thinking: processes, timelines, risks, execution
• Comfortable operating in ambiguity and “build-from-zero” mode

Soft Skills

• Ownership mindset — you build it, you run it
• High autonomy and decision-making ability
• Strong communication and stakeholder management
• Pragmatic, hands-on, result-driven
  Calm under pressure, allergic to chaos (or at least good at taming it)

Languages

• English — fluent

• Ukrainian / Russian — fluent

   

Why Skogos?

• Full Ownership: CEO role with signing authority and account access
• Strategic Impact: Shape the Canadian business from day one
• Global Exposure: Work in a high-tech, international fintech holding
  Growth Path: Clear evolution into a full-fledged CEO / Managing Director

About Tie

Tie is building the next generation of identity resolution and marketing intelligence. Our platform connects hundreds of millions of consumers across devices, browsers, and channels—without relying on cookies—to power higher deliverability, smarter targeting, and measurable revenue lift for modern marketing teams.

At Tie, AI is not a feature—it is a core execution advantage. We operate large-scale identity graphs, real-time scoring systems, and production ML pipelines that directly impact revenue, deliverability, and customer growth.

The Role

We are looking for a Senior AI / Machine Learning Engineer to design, build, and deploy production ML systems that sit at the heart of our identity graph and scoring platform. You will work at the intersection of machine learning, graph data, and real-time systems, owning models end to end—from feature engineering and training through deployment, monitoring, and iteration.

This role is highly hands-on and impact-driven. You will help define Tie’s ML architecture, ship models that operate at sub-second latency, and partner closely with platform engineering to ensure our AI systems scale reliably.

What You’ll Do

• Design and deploy production-grade ML models for identity resolution, propensity scoring, deliverability, and personalization
• Build and maintain feature pipelines across batch and real-time systems (BigQuery, streaming events, graph-derived features)

Why This Role Matters

At Tie, your work will not live in notebooks or experiments—it will power production systems used by real customers at scale. You will help define how AI is embedded into the company’s core platform and play a key role in making machine learning a durable competitive advantage.

Intetics Inc., a global technology company providing custom software application development, distributed professional teams, software product quality assessment, and “all-things-digital” solutions, is seeking a highly skilled and experienced Senior Python Fullstack Engineer to join our dynamic team on a full-time basis.

About the project:

This project offers a unified platform that consolidates vulnerability, threat, and asset data, enabling organizations to effectively prioritize and remediate critical exposures. By integrating information from over 150 security tools, it provides a centralized hub for risk-based vulnerability management, automating workflows, and enhancing security outcomes. The platform is designed to scale and streamline vulnerability and exposure management programs, ensuring efficient mitigation of potential threats

Role Overview

As a Senior Software Engineer in our Engineering team, you'll operate at the frontier of innovation, taking early ideas and high-level product vision and translating them into real, impactful software.

You’ll work closely with product and security experts to design and build new features, services, and tools that push the boundaries of what’s possible in vulnerability management.

This role offers a balanced blend of backend and frontend development, with approximately 50% of your time spent architecting scalable backend systems and the other 50% dedicated to crafting dynamic, user-focused frontend experiences.
 

What You’ll Do

- You will work with founders, multiple members of the R&D team, and the engineering team to develop new, experimental technologies.

- The core responsibility is to develop our new to market, AI-driven vulnerability intelligence platform and data feed. Take ownership of design, implementation, and deployment in conjunction with the R&D team.

- Collaborate with cross-functional teams across the globe, each working in different technology stacks.

- Build scalable backend systems using Python (Django) and MySQL or SingleStore.

- Develop dynamic and responsive user interfaces with TypeScript, React and Tailwind.

- Investigate and incorporate emerging trends in cybersecurity into product ideas.

- Write clean, maintainable, and well-tested code.

- Participate in architectural discussions and code reviews.

Requirements

- 5+ years of professional software engineering experience.

- Proven ability to thrive with minimal direction, especially in ambiguous or R&D-heavy environments.

- Strong backend development experience with Python, Django 4.2, and the Django REST Framework.

- Solid front-end development experience with TypeScript + React 19

- Experience with relational databases, especially MySQL.

- Experience with docker and containerization.

- Experience working in cloud environments, ideally AWS.

- Familiarity with Agile/Scrum methodologies in a professional setting.

- Mindset: Creative thinker who enjoys solving hard problems and experimenting with novel solutions.

- Cybersecurity Passion: Demonstrated interest or background in cybersecurity. Experience in vulnerability management, threat intelligence, or related domains is highly desirable.

Will Be Plus:

- Experience working on multiple projects at the same time

- Experience with big data analytical systems such as Big Query, Redshift, Snowflake, Databricks, SingleStore, etc...

- Experience working with vulnerability scanning technologies on any part of the tech stack (e.g., SCA, SAST, DAST, IAST, VM Scanning, Container, etc.)

- Experience maintaining applications on Linux platforms in cloud environments.
