Headway Inc is a global tech company, revolutionizing lifelong learning by creating digital products for over 150 million users worldwide. Our mission is to help people grow. We’re proud to be ranked 4th among the World’s Top EdTech Сompanies by TIME magazine. We believe lifelong learning should be accessible, personalized, and impactful to each individual. That’s how we change the world and why we bring together exceptional minds.

The core of our achievements is our team. We believe in people and shared values SELECT. That’s why, together with Vladyslav Kiriushkin - Engineering Manager at Platform tribe, we’re looking for a Senior Backend Engineer to join our new team transforming the EdTech industry.

What will you do:

• Build and evolve backend services for a new mission-critical product, from MVP to broader adoption.
• Implement reliable transactional workflows: clear state handling, safe retries, and consistent data persistence.
• Integrate with external partners/systems and make integrations production-grade (edge cases, timeouts, partial failures).

• Balancing delivery and engineering quality: shipping fast while still keeping the codebase maintainable (tests, clear interfaces, documentation);
• Cross-team dependencies: progress may depend on aligning with other teams’ timelines and changes in existing systems, so communication and coordination are part of the job.

What do we offer:

• Work within an ambitious team on a socially impactful education product.
• An office with a reliable shelter, generators, satellite internet, and other amenities.
• Access to our corporate knowledge base and professional communities.

Our Mission and Vision

At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies.

To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world.

About the Team and Role

You’ll join the Billing team and take ownership of the Taxes module — a core part of our billing system responsible for tax calculation and reporting across multiple locations.

The product has already moved beyond MVP and is actively used by customers. The foundational logic is in place, demand is high, and the next step is scaling functionality and reliability.

This role is exciting because you’re not maintaining legacy code — you’re building and shaping a critical system almost from scratch. 
You will have a clear path to Lead: full ownership of the Taxes direction, architectural decisions, and growing a team around it.

Your team — Product Owner, 1 Senior Engineer, Automation QA, and Tax Manager.

What you’ll own

• building tax calculation and reporting logic
• integrating third-party tax providers
• improving system resilience and uptime
• making architectural decisions and setting technical direction
• mentoring engineers as the team grows

In the first months, you’ll deliver key tax functionality and lay a solid foundation for future product and team growth.

We rely on automated testing over manual QA — unit, integration, functional, and e2e tests are a core part of how we ship and scale safely.

You’re a great fit if you have

• 4+ years of backend engineering experience
• 1.5+ years of commercial Go development
• Strong understanding of high-load system design
• Solid experience with PostgreSQL
• Experience with queues or streams
• Strong testing culture: unit, integration, functional, e2e

• Proactive, independent, result-oriented mindset

   

Nice to have

• Kafka
• AWS services
• CI/CD pipelines
• Fintech / payments / financial domain experience

• Understanding of VAT, GST, Sales Tax

   

Why Solidgate?

High-impact role. You’re not inheriting a perfect system — you’re building one.

Great product. We’ve built a fintech powerhouse that scales fast. Solidgate isn’t just an orchestration player — it’s the financial infrastructure for modern Internet businesses. From subscriptions to chargeback management, fraud prevention, and indirect tax — we’ve got it covered. We hold financial licenses in key regions and are a direct Visa & Mastercard partner and sub-reseller (top 5 globally).

Massive growth opportunity. Solidgate is scaling rapidly — this role will be a career-defining move.

Top-tier tech team. Work alongside our driving force — a proven, results-driven engineering team that delivers.

Modern engineering culture. TBDs, code reviews, solid testing practices, metrics, alerts, and fully automated CI/CD.
