Job Description

Senior Python engineer(with React)

Application Deadline: 31 May 2026

Department: Engineering

Employment Type: Full Time

Location: Kyiv, Dnipro

Since 2013, Techery has been bridging the gap between business vision and technology. As a product and consulting company, we focus on building our own products that are both technologically advanced and tailored to meet real-world needs. Every product we create delivers tangible value and drives business growth. Innovation is at our core, and we are increasingly leveraging the power of AI to develop cutting-edge features and explore new possibilities within our product portfolio.
Beyond our product development, we act as a consulting software company for non-tech clients and are in full charge of solving their challenges. Whether it’s addressing complex issues or turning innovation into reality, our commitment ensures that the best visions are fully realized, providing clients with comprehensive solutions that drive success.

Key Responsibilities

Phase 1 (Initial):

• Rapidly deep-dive into a large, complex production codebase to understand system architecture and business logic
• Own diagnosis and resolution of authentication and identity-related incidents, driving issues to root cause — not just symptoms
• Establish and improve internal engineering documentation, turning tribal knowledge into scalable processes
• Evaluate existing runbooks and identify gaps — rewrite or extend them where the current tooling falls short

Phase 2 (Transition):

• Deliver backend fixes and improvements across Python services, including database optimization and SQL query performance
• Extend your impact to the frontend where needed — React contributions that complete the full picture of a fix or feature
• Take ownership of Auth0/OAuth integration quality — identify weaknesses, propose improvements, and implement them
• Raise the team's testing standards by authoring unit and integration tests that become the benchmark for coverage
• Collaborate closely with the product team to shape and ship new features end-to-end, from scoping to deployment

Skills, Knowledge and Expertise

• Strong Python backend development and SQL/database knowledge
• React and TypeScript — comfortable owning frontend changes when needed
• GraphQL and working with graph-based APIs in production
• Deep understanding of IAM systems, identity providers, and SSO implementations
• Familiarity with OAuth 2.0 and modern authentication protocols
• Auth0 experience is a strong plus (not required)
• Systematic approach to diagnosing and resolving complex production issues
• Proven ability to navigate and contribute to large codebases quickly
