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 Germany.

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.
