The Role
We're looking for a capable Full Stack Engineer with a strong focus on backend development, who can also contribute to frontend work. You'll play a key role in designing, building, and maintaining our AWS-based serverless architecture and Angular frontend applications.
This is a hands-on individual contributor role, best suited for someone who enjoys solving technical problems, writing clean, well-tested code, and working in a collaborative but lean environment.
We're particularly keen to find someone who can complement existing expertise—bringing their own strengths while also being open to learning and teaching. This role offers an opportunity to push boundaries and explore better or more efficient ways of doing things.
Requirements
Key Responsibilities
* Design, build, and maintain highly optimised, secure backend services on AWS using serverless and microservices patterns.
* Contribute to the Angular frontend, ensuring well-structured and reliable user interfaces.
* Champion a robust automated testing culture across unit, integration, and end-to-end (E2E) levels.
* Independently set up and manage AWS resources (e.g. Lambda, DynamoDB, S3, Cognito) with minimal input beyond requirements (e.g. Jira tickets).
* Evaluate and adopt additional AWS services where beneficial to improve efficiency, scalability, or best practices.
* Troubleshoot, debug, and resolve issues across the stack.
* Collaborate on system design, specification, deployment, and occasional customer/internal support (approx. 20% of time).
Technical Skills & Capabilities
* Proven experience building production-ready services on AWS (e.g. Lambda, DynamoDB, API Gateway, S3, Kinesis).
* Strong focus on backend performance engineering in high-throughput, data-intensive systems.
* Practical experience implementing comprehensive automated testing strategies.
* Skilled at debugging and resolving issues in live systems.
* Comfortable contributing to frontend development, ideally with Angular.
* Awareness of authentication and security best practices in cloud-native environments.
Nice to have
* Familiarity with MQTT and IoT concepts.
* Additional skills in embedded C programming (e.g. Nordic Bluetooth chipsets).
Ideally, we're looking for someone who:
* Thrives as an individual contributor—hands-on, detail-oriented, and motivated by technical challenges.
* Enjoys designing, specifying, writing, and testing code, rather than focusing on project management.
* Balances core engineering work with customer and internal support.
* Is excited to contribute in a flat organisation where ownership, collaboration, and initiative matter more than hierarchy.
* Is eager to share knowledge while also learning from peers, fostering mutual growth.
* Has the confidence to challenge existing approaches and propose better solutions.
Our Stack
* Backend: AWS (Lambda, DynamoDB, API Gateway, S3, Kinesis), Kotlin, Java
* Frontend: Angular
* Protocols & IoT: MQTT, IoT frameworks (desirable)
* Bonus: Embedded C (Nordic Bluetooth chipsets)
Core Company Values – CHILE
* Collaboration – great personal productivity and efficient teamwork.
* Honesty – no politics, no spin.
* Innovation – always questioning and improving.
* Learning – growing every day by building on experience.
* Excellence – striving to make things better, with a balance of ambition and pragmatism.
