• Architecture Leadership: Guide the design and evolution of the Audit Copilot platform, ensuring scalability, security, and traceability across the entire ecosystem. • Cross-Team Impact: Operate beyond your own team by identifying dependencies, mitigating technical risks, and ensuring integrations with Data teams are smooth and performant. • Operational Excellence: Define and uphold reliability standards (SLOs) and observability, turning incident learnings into systemic improvements to reduce toil. • Mentorship and Culture: Raise Arvo’s technical bar by mentoring engineers, promoting rigorous design reviews, and spreading best practices (TDD, CI/CD, Clean Architecture). • Strategic Partnership: Collaborate with Product to refine the technical scope of ambiguous initiatives, balancing trade-offs between delivery speed and technical debt.

Role Description As a Full Stack Software Engineer, you will contribute to the development of programmatic advertising solutions, ensuring that ad formats such as D2S, InVideo, and Price–Product Video can be configured, delivered, tracked, and optimised across different programmatic pathways. Your responsibilities will span both backend and frontend development, with a strong focus on building reliable, cloud-based systems for programmatic advertising products. Here are some examples of what you will work on: - Develop and maintain backend services and RESTful APIs that power programmatic advertising products - Contribute to integrations with external ad platforms (e.g. Adform, DV360), ensuring correct campaign configuration, delivery, and tracking - Build and evolve frontend components used to configure, visualise, and manage advertising campaigns - Work with relational and NoSQL databases to store and retrieve campaign, delivery, and tracking data - Collaborate with Product and Design to translate requirements into technical solutions - Write clean, readable, and maintainable code, following established coding standards and best practices - Support production systems by debugging issues and contributing to monitoring and reliability improvements - Participate in code reviews, learning from feedback and progressively increasing ownership and impact Qualifications - 2–4+ years of backend development experience - Knowledge of PHP and MVC frameworks such as Laravel or Symfony - Experience with Node.js, ideally in cloud environments (a plus if used with AWS Lambda) - Experience designing and developing RESTful APIs - Solid understanding of clean code principles and basic design patterns - Experience with relational and/or NoSQL databases (e.g. MySQL, DynamoDB) - Awareness of performance, security, and scalability considerations - Knowledge of modern client-side development: HTML5, CSS3, JavaScript (ES6+) - Familiarity with modern JavaScript frameworks and libraries, such as React - Familiarity with component-based architectures - Understanding of frontend build tools and workflows - Ability to collaborate on frontend codebases integrated with backend services - Proficient with Git and common branching strategies - Experience with unit testing and basic integration testing - Ability to debug issues and support production systems - Experience working in collaborative, distributed teams Requirements - Experience with micro-front end architectures, including iframe-based patterns - Experience with rich media banners and creative development in a media or advertising context (e.g. ad formats, creatives, campaign-driven UIs) - Familiarity with TypeScript and its use in modern web applications - Hands-on experience with AWS (even partial or guided) - Familiarity with core AWS services such as Lambda, API Gateway, S3, DynamoDB or RDS, IAM (basic understanding) - Exposure to event-driven architectures (SNS, SQS, EventBridge) - Knowledge of serverless architectures and frameworks (e.g. Serverless Framework) - Exposure to CI/CD pipelines (e.g. GitHub Actions, GitLab CI) - Basic knowledge of containerisation (Docker; Kubernetes is a plus) - Familiarity with monitoring and observability tools (e.g. CloudWatch) - Initial experience with microservices architectures Benefits - An opportunity to thrive in a rapidly scaling multinational company - A vibrant, informal, and inclusive work environment - We champion autonomy, flexibility, and a hybrid work model, empowering you to own your work - Access to learning opportunities and regular feedback sessions - Enjoy our central, modern offices featuring fresh snacks, coffee (including vegan options!), and ergonomic setups - Engage in meaningful team events: offsites, happy hours, company parties and celebrations that unite us beyond daily tasks - We provide all the necessary equipment for you to work effectively and set up your workspace, wherever you are - Benefit from additional country-specific advantages based on local contracts and practices

• Drive end-to-end development across front-end and back-end systems, including requirements analysis, architecture design, feature development, API creation, system maintenance, performance tuning, and troubleshooting. • Contribute to the design and implementation of core system modules; produce comprehensive technical documentation to ensure system stability, security, and high performance. • Actively participate in code reviews, technical design reviews, and release management processes.

• Build and own core product features - Design and implement full-stack features from the ground up: database schema, backend logic, GraphQL API, and React/TypeScript UI • Take full ownership of significant parts of the system: reliability, performance, and long-term maintainability are yours to drive • Participate in every stage of the development lifecycle, from design and implementation to rollout and smooth operation in production • Contribute to and challenge our technical architecture as we scale • Bring genuine backend depth - Design robust data models and schemas built to perform at scale • Build and operate backend services, including background jobs, async pipelines, and integrations with third-party systems • Own observability: instrument systems, define meaningful metrics, and respond to incidents with confidence • Identify and address security risks proactively from API design to infrastructure exposure • Automate deployments via our CI/CD systems and continuously improve development processes • Work with AI as a day-to-day accelerator - Leverage AI tools actively in your workflow, from code generation and review to debugging and documentation, to move faster without compromising quality • Contribute to how we integrate AI-assisted development practices across the engineering team • Stay curious about emerging AI capabilities and bring new ideas on how we can use them to ship better, faster • Be a team force multiplier - Lead technical design on significant features and share your experience openly • Review pull requests with rigor and care, raising the bar for the whole team • Participate actively in team rituals: stand-ups, planning, retros • Contribute to our culture of quality: incremental, well-tested, observable changes • Pursue quality, always - Champion clean code, solid test coverage, and strong engineering practices • Improve processes and methodologies to reach the highest standards • Bring excellence to your own work and help others do the same.
