Role
Who you are
- Extensive experience with modern, object-oriented PHP (v8+), writing clean and maintainable code
- Familiarity with TypeScript, Go, or Python
- Capability to construct efficient, scalable systems that manage high traffic, optimizing performance through profiling, caching, and query tuning
- Direct involvement with cloud-native tools like Docker and Kubernetes, comfortable deploying and managing services in a modern cloud environment with CI/CD and DevOps practices
- Deep knowledge of API design and integration, including OpenAPI/Swagger, REST principles, third-party APIs, and authentication methods like OAuth
- Proficient testing mindset, skilled in writing unit, integration, and end-to-end tests to ensure reliability of critical systems
- Experience working with legacy code and large monoliths, with a history of refactoring and modernizing codebases step-by-step
- Familiar with monitoring and observability tools (e.g., OpenTelemetry, Grafana, APM), able to set up alerts and analyze metrics to keep systems healthy
- Comfortable using AI-powered development tools to improve productivity and code quality
What the job involves
- We’re looking for a Software Engineer to join our newly-formed API team at Supermetrics
- This team was created in 2025 with a bold mission to support an API-first transformation across the company
- As an API Platform Engineer, you’ll have the opportunity to enhance the performance of our platform and the ways in which customers and internal teams interact with it
- Building a Public API Platform: Developing robust, high-performance APIs that productize Supermetrics for our users
- Your work will enable clients to build custom solutions, automations, and even SaaS products on top of our APIs without relying on our UI. In short, you’ll help unlock new ways for customers to use our product through well-crafted APIs
- Implementing an API-First Culture: Shaping our internal shift towards an “API-first” approach by introducing and upholding standards, processes, and governance for both internal and external APIs
- You’ll guide other teams in adopting best practices for API design, documentation (OpenAPI standards), and integration, ensuring consistency and quality across the organization
- Join daily stand-ups, sprint planning, and Jira discussions to align priorities, remove blockers, and turn big ideas into scalable solutions
- Build new API features, improve performance on high-traffic services, and fix bugs using PHP, TypeScript, Go, or Python, ensuring smooth integration with existing systems
- Collaborate closely with teammates through pair programming, code reviews, and knowledge sharing to solve problems and grow together
- Write and maintain unit, integration, and end-to-end tests to ensure reliability; help diagnose and fix production issues, adding tests to prevent recurrence
- Own your work from development to deployment — ship services via Docker/Kubernetes, monitor performance in production, and act promptly to resolve any issues so releases deliver real value
- Work with complex systems: You’ll dive into a large codebase with legacy parts and imperfect APIs, improving and refactoring them to meet new standards. If you like untangling and simplifying messy systems, you’ll enjoy this
- Build for scale: Our products handle heavy traffic and massive data volumes, so performance matters. Even small changes can greatly improve performance — you’ll focus on writing efficient code and optimizing for speed and scalability
- Collaborate across teams: Much of our work enables other teams whose goals might not always match ours. You’ll need to communicate well, find common ground, and help them get the most from our APIs
- Champion API-first: You’ll promote modern API design and best practices across the company, from documentation and training to code reviews
Our take
Helsinki-based Supermetrics is a data integration platform making it easy for marketers and business intelligence teams to analyse data from popular ad platforms such as Facebook, Google and Twitter and integrate them into their preferred analytics and data warehouse platforms.
Despite competition from companies such as Fivetran and Adverity, the company boasts an impressive client list, including Nestlé, Warner Brothers, L’Oréal, owing to its variety of products, such as Supermetrics for Google Sheets, Excel, and BigQuery.
Supermetrics success is product-led and due to the increase in demand for its offerings, the company witnessed a growth of 40% YoY in 2022. Going forward, the company is focused on continuing its strong growth path and hopes to at least double its turnover. It's also emphasising its presence in the US market as important and expects to grow fast.
