Full-Stack Engineer (f/d/m)

Most AI localization platforms come from AI generalists. Alocai comes from inside Altagram, an independent game localization studio operating since 2013, with senior full-time teams of project managers, linguists, and QA testers across six countries and four continents, serving AAA publishers on console, PC, and mobile titles. R&D started in 2019 with an EU Horizon 2020 grant. In production since 2021 across 35+ languages, shaped by the people who localize games for a living.

The moment

You are joining at a build moment. The 2021 platform proved itself in real production pipelines. We are now rebuilding for what comes next: broader and more ambitious. The role is to ship that next version, end to end.

How we work with AI

AI is becoming part of how we ship. Our engineers use AI tools daily, ship LLM-powered features to production, and review AI-generated code with the same scrutiny as any other code. We are hiring engineers who already work this way. 

Your role

• Own and evolve the codebase alongside other developers, as well as the technology infrastructure behind our products.

• Build and maintain both backend services and user-facing features, from API design to component implementation to end-to-end workflows.

• Translate designs and wireframes into well-structured, testable, and scalable code.

• Use AI-powered coding assistants and development tools as part of your daily workflow: writing, reviewing, and shipping code more efficiently.

• Write unit, integration, and end-to-end tests to ensure code quality and reliability.

• Review other engineers' work, including evaluating AI-generated code for correctness, security, and maintainability.

• Contribute to technical decisions and architecture discussions with a mindset toward scalability, modularity, and clean separation of concerns.

• Stay curious about emerging technologies, particularly in AI tooling and LLM capabilities, and proactively propose ways to improve our products and workflows.

• Communicate effectively across technical and non-technical teams, understanding that great products need a tight feedback loop between development and product.

• 3–5 years of professional software development experience with agile methodologies.

• 2+ years of working with Python in a professional backend or full-stack capacity.

• Strong proficiency in JavaScript/TypeScript, HTML, and CSS.

• Experience with React.js and a solid understanding of its core principles.

• Experience designing and integrating RESTful APIs.

• Demonstrated, practical use of AI-assisted development tools (e.g., GitHub Copilot, Claude, Cursor, or similar) to accelerate coding, debugging, and code review workflows.

• Commitment to software testing and high test coverage, with experience using testing frameworks (Jest, React Testing Library, pytest, or similar).

• Understanding of scalability, modularity, and separation of concerns in system design.

• Proficiency with Git, branching strategies, and pull request workflows.

• Basic understanding of DevOps, CI/CD pipelines, and deployment workflows.

• Familiarity with cloud platforms such as AWS or Azure.

• Understanding of web performance optimization.

• Fluent English communication skills, with the ability to present technical information clearly to varied audiences.

• Collaborative mindset and willingness to share knowledge across teams.

Nice to have

• Bachelor's or Master's degree in Computer Science or a related field.

• Experience integrating LLM APIs (OpenAI, Anthropic, or similar) into production applications.

• Familiarity with AI/ML engineering concepts such as RAG pipelines, vector databases, prompt engineering, or agent orchestration.

• Experience building or contributing to AI-powered features within user-facing products.

• Familiarity with frontend build tooling (Babel, Webpack, NPM) and newer ECMAScript specifications.

• Experience with container-based deployment and orchestration (Docker, Kubernetes).

• Familiarity with monitoring and observability tools (Sentry, LogRocket, Datadog).

• Knowledge of modern authentication/authorization mechanisms (e.g., JWT).

• Prototype-oriented mindset. You expect early versions to need iteration and welcome refactors, user feedback, and prioritization.

• Ability to separate product, implementation, architecture, and coding discussions to keep the team efficient.

• Built inside Altagram. The same teams that run production workflows shape the product.

• Backed by an EU Horizon 2020 grant in 2019. In production since 2021. Five years of real production data behind every decision.

• Alocai is a full platform: AI, project workflows, communication, and quality controls, used daily by linguists, project managers, and indie-to-AAA studios. The engineering challenge is shipping faster at high quality.

• A major rebuild is underway. You join early and help ship it from architecture to launch.

• Small team. Engineers make engineering decisions.

• Work from our Berlin office or fully remote (CET timezone) — your choice.
