• 1+ years of hands-on experience contributing to UI or API automation using Playwright and TypeScript (familiarity with POM and clean code principles).
• Practical understanding of e-commerce logic: order lifecycles, shopping cart mechanics, checkout, and payment flows.
• Experience testing REST/GraphQL APIs (Postman/DevTools) and writing SQL (MySQL) queries for verification and test setup.
• Familiarity with Web fundamentals (HTML/CSS, DevTools, Charles/Fiddler proxy tools) and practical Git/GitFlow experience.
• AI-assisted engineering: practical ability to use AI tools (ChatGPT, Claude, Gemini or others) to speed up test design, debugging, reporting and script writing, while critically validating output.
• Soft skills: strong proactivity, analytical mindset, customer-centric approach, and clear communication skills.
• Intermediate English level or higher for daily communication and documentation.

Bonus points

• Experience testing healthcare-related products, medical platforms, or HIPAA/EHR workflows.
• Hands-on experience with the Magento 2 platform.
• Experience testing payment integrations and subscription lifecycles (recurring billing, cancellations).
• Experience with CI/CD pipelines (GitHub Actions, Jenkins) or Docker.

Team & culture

You'll work closely with the QA Team Lead and software engineers in a proactive environment where every voice matters. We support your growth through individual development plans, helping you optimize testing workflows, scale automation coverage, and dive deeper into automation architecture or CI/CD over time.

Benefits

• Competitive compensation based on your skills and experience.

This is not a role for someone who wants control loops handed to them pre-tuned: you will design, implement, and validate them on hardware yourself.
 

Responsibilities:

• Implement navigation and control algorithms for different types of UGVs: differential drive, tracked wheels, Ackermann steering, etc.
• Design and implement control algorithms (PID and beyond) that translate navigation commands into reliable robot motion.
• Own the control stack end-to-end — from algorithm design through tuning and validation on the physical unit.
• Simulate physical driving for different types of wheels and terrains before deploying to hardware.
• Work closely with the Robotics team on actuator and sensor integration, since control quality is only as good as what it’s built on.
• Debug control issues that only show up in the field, not in simulation — this role is hands-on with the physical robot in Lviv.
• Collaborate with the Perception Engineer so control decisions correctly account for obstacle and environment data.
• Propose architecture and design decisions rather than waiting to be handed a fully-scoped ticket: this is a small team building a new capability almost no one in the Ukrainian market has shipped yet.

Requirements:

• Strong mathematical foundation: linear algebra, calculus, and the algorithmic thinking control systems are built on.
• Practical experience with control theory — PID control at minimum, ideally more advanced control approaches.
• Background in robotics, guidance, or navigation systems (e.g., autonomous vehicle guidance, drone terminal guidance, or similar).
• Experience with physics simulators (e.g. Gazebo, NVIDIA Isaac, MATLAB, Simulink), with the ability to simulate dynamic models and verify controller performance before deployment.
• Experience working with sensors such as IMU, LiDAR, etc.
• Knowledge of state estimation and filtering (e.g. Kalman filter, extended Kalman filter, complementary filter).
• Solid programming skills in C++ (and Python for prototyping).
• Good OOP skills — ability to write and design clean code that’s flexible to extend and maintain.
• Comfortable working close to hardware, not purely in a software abstraction layer.
• Upper-Intermediate+ English.

Nice to have:

• Experience with ROS/ROS2
• Path planning algorithms (A*, D*, RRT, etc.)
• Prior work on UAV or UGV guidance/navigation systems
• Defense-tech or military-tech industry exposure
• Embedded systems or hardware-adjacent experience

Security Eligibility:

Our platform is actively used by the Armed Forces in live operations. As an Estonian-Ukrainian defence technology company handling sensitive operational data, we have a responsibility — legal, ethical, and practical — to ensure the integrity of everyone on our team.

All candidates must be able to confirm the following:

Neither you nor your close relatives (parents, spouse, siblings, children) reside in Russia, Belarus, or temporarily occupied Ukrainian territories

You have no regular personal, financial, business, or professional contact with individuals in those territories

You consent to a deeper security verification if the process advances to later stages

If any of the above criteria are not met, please do not proceed with your application.

Why Farsight Vision

We are a startup operating under real-world conditions — our product is in active deployment, and the pace reflects that. We are not a company where you get to run the same experiment three times until it’s elegant — we need someone who wants to see their control loop working on a real robot within weeks, not quarters, and who is motivated by the fact that what you build here gets used, not shelved.

Flexible working hours. Paid vacation and sick leave. Direct access to founders and leadership.

Application Process:

• Apply with your CV and a brief cover letter explaining your interest and relevant experience
•  Interview with the Recruiter
•  Interview with VP of Engineering
• Complete a short practical assignment involving a control/navigation problem drawn from our platform
• Interview with  Lead Robotics Engineer

You'll work closely with Affiliate Managers, Marketing, BI, and Product teams to ensure that every acquisition channel delivers real, valuable players while continuously improving fraud detection processes through data analysis and automation.

What You'll Do

• Analyze affiliate traffic performance across partners, campaigns, and traffic sources.

  • Multi-accounting;
  • Bot traffic;
  • Device and identity overlaps;
  • VPN / Proxy usage;
  • Bonus abuse;
  • Fake registrations and deposit patterns;

• Cross-check data between Affilka, tracking platforms, BigQuery, and internal BI tools.
• Build clear evidence-based reports supporting traffic rejection decisions.
• Develop and continuously improve anti-fraud rules, validation logic, and traffic quality standards.
• Identify recurring fraud patterns and recommend preventive solutions.
• Collaborate closely with Affiliate Managers to improve partner quality and optimize acquisition performance.
• Work alongside Marketing, BI, Product, and CRM teams to understand how traffic quality impacts long-term player value.

What We're Looking For

• 1–3+ years of experience in Affiliate Marketing, Traffic Analytics, Anti-Fraud, Media Buying, or iGaming Analytics.
• Strong understanding of affiliate traffic, player acquisition funnels, and common fraud schemes.
• Experience analyzing acquisition quality beyond simple conversion metrics.
• Confident working with large datasets using Excel or Google Sheets.
• Basic SQL skills (SELECT, JOIN, GROUP BY).
• Experience working with platforms such as:
  • Affilka;
  • Keitaro;
  • Voluum;
  • or similar affiliate tracking systems.
• Strong analytical mindset with the ability to justify decisions using data.
• English level B1+.

AI & Automation

We highly value specialists who actively leverage AI to improve efficiency.

Experience using AI tools for:

• automating repetitive workflows;
• building dashboards and reporting;
• data analysis;
• writing SQL queries;
• developing internal analytical tools;

• Full-time remote position.
• Working hours: Monday–Friday, 10:00–19:00 (EET).
• A fast-moving product environment where data drives decision-making.
