Senior AI Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior AI Engineer based in Romania.

As a Senior AI Engineer, you’ll build and evolve products that are integrated directly into partner platforms and supported by robust backend <systems.You>’ll work end-to-end across TypeScript/React and Golang, with the opportunity to bring depth in one area while developing expertise across the stack.AI-assisted development is already central to the engineering workflow, so you’ll be expected to use agentic coding tools confidently in production.The role combines hands-on engineering with architectural influence across APIs, distributed systems, cloud infrastructure, and product <functionality.You>’ll contribute to systems where reliability and correctness are critical, including wallet-related flows and certified, audited game environments.Working within an autonomous and collaborative product team, you’ll have significant freedom to make technical decisions and improve engineering practices.This is an opportunity for a senior engineer who wants to help shape both the technology and the future of AI-first software development.

Accountabilities

• Deliver end-to-end functionality across a TypeScript/React frontend and Golang backend.
• Build and maintain products designed for integration into third-party platforms and partner ecosystems.
• Develop and improve wallet systems and related flows, with a strong emphasis on correctness, reliability, and security.
• Build and operate game-related systems within certified and audited environments.
• Design, implement, and maintain APIs using GraphQL, gRPC, REST, and other appropriate patterns for internal applications and external integrations.
• Contribute to the architecture and technical evolution of a young, cloud-based platform running primarily on AWS.
• Design and develop reliable event-driven and distributed systems capable of handling concurrency effectively.
• Work with SQL and NoSQL databases, including technologies such as PostgreSQL, Redis, and DynamoDB.
• Use AI-powered development tools as a core part of the software delivery workflow, while applying strong senior-level judgment to review, validate, and verify AI-generated code.
• Help define and improve AI-assisted engineering practices across the wider development team.
• Participate in code reviews, knowledge sharing, and technical discussions to support the growth of other engineers.
• Collaborate within an autonomous, fast-paced product team while working remotely across European time zones or from a designated office environment.

Requirements

• At least 5 years of professional experience building and shipping production software.
• Strong expertise in either TypeScript/React or Golang, combined with solid competence across the other side of the stack.
• Experience using AI coding tools such as Claude Code, Codex, Cursor, or similar technologies to ship production software on a daily basis.
• Ability to demonstrate practical experience building software with AI-assisted or agentic development workflows.
• Strong interest in driving responsible and effective AI adoption across an engineering team.
• Engineers with strong Java, Kotlin, or C# backgrounds are also welcome if they are motivated to develop Golang expertise.
• Solid understanding of event-driven architectures, distributed systems, concurrency, and scalable software design.
• Experience building and operating services backed by SQL and NoSQL databases, such as PostgreSQL, Redis, and DynamoDB.
• Familiarity with modern API design approaches, particularly GraphQL, gRPC, or REST.
• Professional experience deploying and operating applications in cloud environments such as AWS, Azure, or Google Cloud.
• Pragmatic understanding of testing, with the ability to balance test coverage, development speed, and product risk.
• Strong engineering judgment, problem-solving ability, and attention to correctness and reliability.
• Comfortable working autonomously in a fast-moving environment with minimal bureaucracy and evolving processes.
• Strong communication and collaboration skills, including the ability to contribute effectively through code reviews and knowledge sharing.
• Experience building frontend components that are embedded within third-party products, such as widgets or SDKs, is a plus.
• Experience working with real-money systems is advantageous.
• Knowledge of Kafka, Terraform, or Docker is a plus.

Benefits

• Fully remote opportunity for candidates working within the European time zone.
• Flexible, autonomous working environment with no rigid or unnecessary processes.
• Opportunity to work on products that are integrated directly into partner platforms.
• Significant technical ownership and the ability to influence the architecture of a growing platform.
• Opportunity to work in an AI-first engineering environment where AI-assisted development is already deeply embedded in the delivery process.
• Chance to help shape AI coding practices and influence how an engineering team adopts emerging development technologies.
• Collaborative product team with strong emphasis on knowledge sharing and peer support.
• Exposure to modern technologies including TypeScript, React, Golang, GraphQL, gRPC, AWS, PostgreSQL, Redis, and DynamoDB.
• Opportunity to work on technically challenging distributed systems and reliability-critical products.
• Potential to work on innovative game and real-money technology operating within certified and audited environments.
