What you will be doing:

We’re seeking a senior-level Fullstack Engineer with a strong preference for F# expertise to join our dynamic team. This role is pivotal in developing and enhancing scalable, reliable logistics applications, encompassing both sophisticated backend services and modern frontend interfaces.

You will be instrumental in driving new architectural patterns and standards, focusing on clean design, operational excellence, and a reliability-first approach. The position involves hands-on development using F# for backend systems and proficiency in React for frontend development. A key aspect of this role includes contributing to the development of automated quality assurance (AQA) tests using the Playwright framework.

You will collaborate closely with cross-functional teams, participate in on-call rotations for production systems, and contribute to a culture that values continuous improvement and thoughtful problem-solving. While F# is preferred, candidates with a solid C#/.NET functional programming foundation and a demonstrated willingness to learn F# will be considered.

Key Responsibilities

• Develop and maintain robust backend services utilizing F#, adhering to best practices for scalable and reliable cloud-hosted applications on AWS.

• Use AI tools to improve your development quality and manual processes.

• Implement and enhance modern frontend features using React, incorporating Server-Side Rendering (SSR) practices.

• Design and implement solutions leveraging event-driven architectures and event streaming concepts, with familiarity in systems like Kafka being advantageous.

• Write comprehensive unit and integration tests for both frontend and backend code to ensure application quality and stability.

• Contribute to the development and maintenance of applications using relational databases, including PostgreSQL and SQL Server, with a strong understanding of SQL, indexing, and debugging.

• Participate actively in the on-call rotation for production systems, focusing on triaging and resolving incidents to minimize downtime.

• Drive the adoption of observability practices, including structured logging and the creation of runbooks, to enhance system operability and maintainability.

• Develop and execute automated tests using the Playwright framework for API testing, contributing to the overall quality assurance process.

• Collaborate with cross-functional teams to define and implement architectural patterns, ensuring applications are designed for operability, scalability, and maintainability.

• Contribute to the continuous improvement of the application portfolio, focusing on enhancing user experience and managing technical debt.

Required Skills & Experience

• Proficiency in F# for backend development; C# with a strong functional programming foundation and a demonstrated willingness to learn F# will also be considered.

• Mid-level proficiency in frontend development with React, TypeScript, and CSS.

• Experience with Server-Side Rendering (SSR) practices, such as htmx or similar technologies.

• Practical understanding of event-driven systems and distributed system concepts, including idempotency and eventual consistency.

• Experience developing cloud-hosted applications on AWS, Azure, or GCP.

• Comfortable working with relational databases, including SQL, indexing, and debugging.

• Experience writing unit and integration tests for both frontend and backend code.

• Familiarity with CI/CD practices and maintaining a strong working knowledge of the tech stack.

• Experience with observability practices, including structured logging and runbooks.

• Experience with AI tools like Claude, copilot or similar, to improve the coding process and the quality of this.

Nice to Have Skills

• Familiarity with containerization technologies such as Docker and orchestration tools like Kubernetes.

• Experience with event streaming platforms, specifically Apache Kafka.

• Proficiency in developing automated API tests using the Playwright framework.

• Experience with specific AWS services including S3, SQS, SNS, and Lambda.

• Knowledge of infrastructure as code tools, such as Terraform.

• Familiarity with GitHub Actions for CI/CD pipelines.

• Experience with both PostgreSQL and SQL Server relational database engines.

• Exposure to F# front-end DSLs for server-side rendering (SSR).

Soft Skills

• Clear and concise communication, essential for translating complex technical details to cross-functional teams and for articulating design choices through documentation and reviews.

• A strong sense of ownership and a proactive, detail-oriented approach to problem-solving, driving continuous improvement in application development and operational excellence.

• Adaptability and comfort working within distributed teams and fast-paced environments, embracing a culture that encourages experimentation and learning from failures.
