and reliable software solutions. We foster a culture of innovation, ownership, and
continuous improvement, driven by a mission to deliver exceptional value through
cutting-edge development practices. Our team thrives on a "try and fail" mentality,
encouraging bold thinking and collaborative problem-solving. While F# is our
preferred functional programming language, we embrace candidates with a strong
C# and functional programming foundation who are eager to learn and master F#.
We operate within the dynamic logistics technology sector, leveraging modern tools
and methodologies to maintain a strong market position. Our commitment to
operational excellence is reflected in our emphasis on reliability-first design, robust
testing, and effective observability practices. We are a globally distributed team,
united by a passion for technology and a commitment to our clients' success.

Position Overview

Lean Tech is 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. Experience with eventdriven
systems is required, with Kafka being a desirable, though not mandatory,
technology.

Key Responsibilities

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

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.
• Empathetic collaboration, valuing team growth and constructive feedback to
  foster a supportive and innovative development environment.
• A mindset that encourages challenging existing patterns and proposing
  innovative solutions, aligning with Lean Tech's culture of continuous
  advancement.
