What is a mid backend developer?

Mid Backend Developers are software engineers with intermediate experience who focus on building, maintaining, and optimizing the server-side components of web or mobile applications. They typically work with databases, APIs, server logic, and integration with front-end systems. Mid-level developers have a solid understanding of programming languages such as Java, Python, Node.js, or Ruby and are expected to contribute to code reviews, troubleshoot issues, and implement new features under minimal supervision. Their role bridges the gap between junior developers, who need more guidance, and senior developers, who handle architecture and high-level decisions.

What are some typical challenges a mid backend developer might face when integrating new technologies into existing systems?

As a Mid Backend Developer, one common challenge is ensuring that new technologies or frameworks integrate smoothly with legacy systems without disrupting current operations. This often involves understanding both the old and new codebases, data migration, and dealing with compatibility issues. Collaborating closely with frontend developers, DevOps, and QA teams is essential to address potential bottlenecks and maintain performance. Additionally, thorough testing and documentation are crucial to ensure long-term stability and maintainability.

What are the key skills and qualifications needed to thrive as a mid backend developer, and why are they important?

To excel as a Mid Backend Developer, you need strong programming skills in languages such as Java, Python, or Node.js, along with a solid understanding of databases and API design, typically backed by a bachelor’s degree in computer science or related field. Familiarity with tools and systems like Git, RESTful APIs, Docker, and cloud platforms (e.g., AWS, Azure) is usually required. Problem-solving abilities, effective communication, and teamwork are crucial soft skills that set high performers apart. These competencies ensure efficient development, maintainability, and seamless integration of backend services in dynamic technical environments.

Since pioneering our first mobile, solar-powered units, our commitment to scrappy, hands-on innovation has made us an established leader and one of the fastest-growing companies in intelligent site technology. We are building the next generation of solutions-from our physical units in the field to a powerful Agentic AI platform-that allows our customers to gain unprecedented visibility and control over safety, compliance, and operations. This is your chance to join a cutting-edge team that isn't just watching the world change, but actively building the technology that is changing it.
We're a team that's focused on growth and innovation, and we're proud that our crew, products, and leadership are being recognized for it.
  • A Top-Tier Growth Company: Named one of the Financial Times' Fastest Growing Companies 2025 and #10 on the Inc. 5000 Rocky Mountain Regional list for 2025.
  • Innovative Leadership: Our CEO, Ryan Porter, was named an EY Entrepreneur of the Year 2025, and our CTO, Steve Lindsey, was inducted into the Silicon Slopes CTO Hall of Fame in 2024.
  • Product & Software Excellence: We were named one of The Software Report's Top 100 Software Companies of 2023 and are a winner of the Security Today Govies Award for 2025.

ABOUT THIS ROLE
As a Senior Fullstack Software Engineer at LVT, you will play a critical role in designing, building, and scaling software across our entire user interface surface area and the mission-critical backend services supporting it. You will own features end-to-end-from building responsive React applications to optimizing our federated GraphQL subgraphs. Working alongside a highly collaborative team, your engineering judgment will directly shape how enterprise customers interact with real-time IoT data and advanced automated workflows.
ROLE RESPONSIBILITIES
  • Deliver High-Quality Software End-to-End: Design, build, test, and ship robust features across our full stack, ensuring code aligns with high-performance standards from UI components to backend REST and GraphQL services.
  • Cross-Service Architecture & Debugging: Trace, isolate, and resolve complex, systemic bugs across service boundaries (UI, API gateways, subgraphs, and legacy codebases) to ensure seamless performance.
  • API & Data Integrity: Define clear data contracts between microservices, maintain schema federation hygiene, and architect secure, scalable real-time WebSocket data flows.
  • Promote Reliability and Performance: Write and run comprehensive tests, instrument critical system metrics, and build operational dashboards to proactively monitor system health and minimize downtime.
  • Technical Mentorship: Provide technical guidance and constructive code reviews to mid-level and junior engineers, encouraging best practices and continuous learning across the team.
  • Continuous Engineering Improvement: Collaborate across adjacent QA, DevOps, and architecture teams to accelerate CI/CD pipelines, enhance stack-wide type safety, and deprecate legacy systems without disrupting product delivery.

OUR IDEAL CANDIDATE
  • 5+ Years of Professional Development Experience: A proven track record building enterprise-grade applications, with a heavy emphasis on full-stack TypeScript architectures.
  • Frontend & Framework Mastery: Deep production experience working with React and modern Next.js environments (including App Router and server actions).
  • Backend & API Expertise: Strong command of Node.js (NestJS preferred) and hands-on experience designing schemas, resolvers, and subscriptions using Apollo Server or similar GraphQL ecosystems.
  • Data & Real-Time Systems Knowledge: Proficiency with relational databases (MySQL preferred), query builders/ORMs (like Knex), and experience scaling real-time web applications using WebSockets.
  • Security & Infrastructure Fundamentals: Solid understanding of modern authentication/authorization patterns (OAuth/OIDC, JWT) alongside familiarity with Docker, containerization, and modern CI/CD practices.
  • Problem Solver & Systems Thinker: Exceptional analytical skills with the ability to dive into unfamiliar or legacy codebases, deduce business logic, and refactor effectively.
  • Compelling Communicator: Strong interpersonal and collaboration skills, with an innate ability to lead cross-team design discussions and articulate technical strategies clearly to stakeholders.

COMPENSATION
The beginning annual salary range for this role is $159,000 - $192,000 USD and is determined by location, job-related experience, and education/training. Your total earning potential is amplified by a bonus structure tied to meeting goals, and you will become an owner from day one through our employee equity program.
BENEFITS
We believe you do your best work when your whole life is supported. We invest in our crew's health, families, and financial futures with a benefits package designed to support you inside and outside the office. Full-time benefits include, but not limited to: Comprehensive health, dental and vision coverage, retirement benefits (401k match up to 4%), and flexible PTO.
