About Backblaze

Backblaze provides reliable, high-availability cloud storage trusted by consumers, SMBs, enterprises, and developers in over 150 countries. Backblaze B2 Cloud Storage supports data-intensive workloads including backup, media, analytics, and modern AI pipelines. Our teams focus on building secure, durable, scalable systems with a strong emphasis on application security from day one and protecting customers to keep them safe.

But while there is a lot to celebrate in our past, there is almost as much opportunity ahead of us. We are hiring a Sr. Software Engineer to join our Front End Engineering team. This team builds the core customer facing web applications and services that power how customers model, manage, and secure organizations in Backblaze. That includes identity and access foundations, cloud storage resource management, and UI/service implementations  integrated with a modern role-based access control system management that governs access to resources at scale.

About the Role

In this role, you will design and build highly available and modern web applications and services in our TypeScript and React ecosystem. You will work and integrate with systems that sit at the center of customer administration, authorization, and resource orchestration, with design challenges shaped by ideas found in platforms such as AWS IAM, GCP IAM, and Azure RBAC.

This is a strong fit for an engineer who enjoys building modern and scalable production web applications and services, can reason rigorously about security and correctness, and is comfortable owning the full lifecycle (design, implementation, rollout, and operation) of an application integrated with distributed systems. We also value engineers who use modern AI tools effectively to accelerate development, improve design quality, and strengthen security and maintainability.

Responsibilities:

• Design, build, and evolve scalable front end web applications and web application services using Typescript & React with backend JS frameworks like NestJS and NextJS.
• Develop core application functionality like user interfaces and backend-for-frontend code, and integrate with other existing services via REST and gRPC APIs.
• Partner with adjacent platform and product teams to integrate with authentication and other shared systems.
• Write technical designs, break down ambiguous problems, and drive projects from concept through production rollout.
• Own the full delivery lifecycle for the systems you build, including architectural design, testing strategy, deployment, observability, and operational readiness.
• Diagnose and resolve complex production issues involving distributed services and cross-service dependencies.
• Improve system security, correctness, and developer velocity through thoughtful design, automation, and use of modern AI-assisted engineering tools.
• Contribute to engineering excellence through code review, design review, mentoring, and raising the technical bar across the team.
• Collaborate cross-functionally with Product, Security, Quality Assurance (QA), Support, Finance, and other partners to translate business and operational requirements into robust technical solutions.

Required Qualifications:

• 7+ years of professional software engineering experience, with substantial experience building and operating production web applications and services.
• Strong experience with TypeScript/JavaScript and React in a production environment.
• Experience integrating APIs and service interfaces, including compatibility, migrations, and staged rollouts.
• Experience building scalable, complex UIs and debugging issues in production.
• Strong foundation in backend concepts like databases, and API implementation and integration with REST, gRPC or similar interface protocols.
• Experience with containerized development and deployment environments.
• Experience with observability practices and tools for metrics, logging, and operational debugging.
• Sound judgment in frontend architecture, access control concepts, and frontend application security fundamentals.
• Demonstrated ability to lead technical work across the full software development lifecycle.
• Strong written and verbal communication skills, including the ability to collaborate effectively across engineering and non-engineering partners.

Preferred Qualifications: 

• Experience with Protocol Buffers and gRPC, and TypeScript/JavaScript based backend frameworks and services
• Experience with Vitess or other large-scale SQL platforms.
• Experience integrating with internal and external APIs
• Experience working across a polyglot stack that includes backend and TypeScript-based clients and tooling.
• Practical experience using AI-assisted development tools such as Cursor, Claude Code, Gemini, or similar to improve engineering productivity and code quality.
• Experience mentoring engineers and influencing technical direction beyond your immediate project area.

Summary of Role:

As a Software Development Engineer III at Palmetto, you will play a key role in designing, building, and scaling critical platform services using the MERN stack (MongoDB, Express, React.js, Node.js). You’ll work hands-on across the stack, with a stronger emphasis on server-side architecture and API development, while collaborating closely with product, design, and engineering teammates.

This role is ideal for a passionate, growth-minded engineer who thrives in an Agile environment, brings ideas to the table, and has the technical depth to contribute to platform evolution and system scalability.

You’ll work alongside, not for, other team members – contributing your ideas, code, and energy to shape solutions that drive business outcomes and customer satisfaction.

Key Responsibilities:

Strategic & Tactical 

• Design and implement scalable client- and server-side solutions, with an emphasis on APIs, backend services, and database integration.
• Write high-quality, testable, and maintainable code across the full stack.
• Develop and maintain comprehensive unit, integration, and end-to-end tests.
• Diagnose and troubleshoot production issues and propose robust solutions.
• Participate in Agile ceremonies (planning, grooming, retrospectives) and contribute to meaningful story estimations.
• Engage in architectural discussions, technical design reviews, and contribute to Palmetto's engineering standards.
• Identify and advocate for opportunities to improve system performance, reliability, and developer productivity.
• Partner cross-functionally with product managers, designers, and QA to deliver well-rounded user-centric solutions.

Team & Culture

• Actively participate in peer code reviews with a focus on knowledge sharing, mentorship, and maintaining high-quality code standards.
• Collaborate openly with others to help cultivate a culture of learning, innovation, and continuous improvement.
• Demonstrate an ownership mindset by anticipating future needs and contributing to long-term technical roadmap discussions.

Minimum Qualifications 

• 5+ years of professional software engineering experience.

• Proficiency with Node.js, Express, and experience designing/consuming RESTful APIs.
• Experience building and maintaining Single Page Applications (SPAs) with React.js.
• Hands-on experience working with NoSQL/document-based databases (e.g., MongoDB).
• Solid understanding of core web fundamentals (HTML, CSS, security, performance).
• Strong unit and integration testing discipline; TDD experience a plus.
• Familiarity with CI/CD pipelines, code versioning (Git), and modern development workflows.
• Excellent written and verbal communication skills.
• Strong problem-solving skills, a continuous learner mentality, and a commitment to team success.

• Experience with Fastify, NestJS or other Node.js frameworks beyond Express.
• Familiarity with server-side rendering concepts and isomorphic React applications.
• Knowledge of authentication and authorization patterns (e.g., OAuth, JWT).
• Experience with front-end build tools (Webpack, Vite, Babel, etc.).
• Exposure to containerization (Docker) and cloud platforms (AWS, GCP, Azure).
• Interest or experience in microservice architecture and event-driven systems.
