About FyrFly Venture Partners

FyrFly Venture Partners is a leading innovator in the field of frontline worker enablement. We believe in harnessing the power of technology to drive productivity, quality, and safety for our clients' frontline teams.

We're on a mission to digitally empower frontline workers, and we need a talented Senior Fullstack Software Engineer to help us innovate and expand our platform.

About the Role

  • Develop High-Quality Features: As a Senior Fullstack Software Engineer, you will design, implement, and maintain end-to-end features across our front-end (Vue.js, JavaScript/TypeScript) and backend (Java) systems.
  • Collaborate Across Teams: You will work closely with product managers, designers, and DevOps engineers to plan, build, and deliver customer-centric solutions.
  • Ensure Reliability and Scalability: You will write clean, efficient, and scalable code that upholds performance, security, and reliability standards.
  • Drive Best Practices: Conduct code reviews, provide mentorship to junior engineers, and champion best practices around testing, documentation, and maintainability.
  • Optimize System Performance: Profile and troubleshoot performance issues, ensuring our products continue to deliver a seamless experience under increasing load.
  • Maintain and Evolve Architecture: Contribute to architectural discussions, influence technical decisions, and help evolve our stack with new technologies and frameworks.
  • Take Ownership: Participate in on-call rotations when needed, and assume operational responsibility for the services you develop.

What We Look For In You

  • 5+ Years of Software Engineering Experience: Demonstrated expertise in both backend and frontend development for modern, cloud-based applications.
  • Proficiency in Backend Languages: Strong skills in Java; familiarity with frameworks such as Quarkus or Spring Boot is a plus.
  • Front-End Mastery: Hands-on experience with JavaScript/TypeScript and front-end frameworks (e.g., Vue.js, React, or Angular).
  • Cloud & Containerization: Experience with AWS or GCP, Kubernetes, and Docker for deploying and scaling applications.
  • Microservices & Distributed Systems: Solid understanding of event-driven architectures, messaging systems (Kafka, RabbitMQ), and RESTful API design.
  • Database Expertise: Comfortable working with SQL and NoSQL databases (e.g., PostgreSQL, MySQL, ClickHouse).
  • Quality Focus: Passionate about code quality, testing, and continuous refactoring to maintain high engineering standards.
  • Excellent Communication: Ability to collaborate effectively in cross-functional teams; proficiency in English (speaking and writing).
  • Mentorship & Leadership: Willingness to guide junior engineers and drive technical initiatives across the organization.

Bonus Points

  • Exposure to AI/ML: Familiarity with AI, prompt engineering, or integration of LLMs.
  • DevOps & Infrastructure: Experience with Infrastructure-as-Code tools like Terraform or Spacelift, and observability platforms such as Prometheus and Grafana.
  • Product-Led Growth (PLG): Knowledge of PLG frameworks, continuous onboarding strategies, or experience with tools like Mixpanel, Pendo, and Hotjar.
  • B2B/SaaS Experience: History of shipping software in a SaaS environment.
  • Open Source Contributions: Active participation in open source communities or related technical forums.
