Full-Stack Engineer

Position Overview

Speer Technologies is seeking a Full Stack Developer to join our growing engineering team. This is a hands-on role where you will contribute production-quality code from day one, working across both frontend and backend systems in a fast-moving startup environment.

You'll join a tight-knit engineering silo of 8-9 developers, shipping code to production frequently and taking ownership of meaningful features and systems. We value engineers who understand fundamentals deeply, solve problems independently, and move with urgency. Whether you're building server-side components, integrating APIs, or collaborating on sprint planning, your work will have a direct and visible impact.

We are hiring across experience levels, so even if you don't check every box below but believe you have the fundamentals, the drive, and the curiosity to thrive in a fast-paced environment, we want to hear from you. Apply anyway!

Key Responsibilities

• Full-Stack Development: Design, develop, test, and deploy high-quality, scalable web and mobile applications across the full stack, with a strong emphasis on JavaScript and Node.js.
• Backend Engineering: Develop and implement low-latency, highly performant server-side components by writing efficient, reusable, and maintainable code.
• Frontend Collaboration: Work closely with frontend developers and UX/UI designers to build visually appealing, functional interfaces and ensure seamless integration of application elements.
• Code Quality & Testing: Maintain high personal code standards through peer reviews, unit testing, and automated test coverage. Give and receive constructive feedback to continuously raise the bar.
• Security & Data Integrity: Implement effective security protocols and data protection measures across applications and infrastructure.
• Continuous Improvement: Proactively identify and resolve defects, contribute suggestions to enhance performance and usability, and keep your skills current with emerging technologies and best practices.
• Agile Delivery: Collaborate with a cross-functional team to plan, design, and execute sprints in an agile, high-velocity environment where code ships to production frequently.
• Problem Solving: Navigate ambiguous, fast-moving technical challenges with creativity and sound engineering judgment. Figure things out independently; pull in help only when genuinely blocked.
• AI-Augmented Development: Leverage AI tools and modern developer workflows to rapidly prototype software, accelerate iteration cycles, and explore solutions faster than traditional approaches allow.

Qualifications

• 5+ years of experience in software development.
• JavaScript: Strong proficiency in JavaScript (the backbone of our codebase).
• Backend: Experience with at least one popular backend framework such as Node.js, Express.js, or equivalent.
• Fundamentals: Solid understanding of core computer science concepts, including concurrency, synchronous/asynchronous programming, and database fundamentals.
• Strong skills writing testable, maintainable code with a foundation in unit testing.
• Proficient understanding of code versioning tools such as Git.
• Familiarity integrating with external APIs and SDKs.
• Comfortable working independently on open-ended, fast-paced initiatives in a startup environment.
• Excellent verbal and written communication skills, with the ability to collaborate effectively across a diverse team.
• Demonstrated ability to understand and explain the code you ship, not just how to generate it, but why it works and how to fix it when it breaks.

Nice to Haves

• Experience with React or comparable frontend frameworks.
• Familiarity with MongoDB, Redis, or other data storage solutions.
• An agile mindset with experience working in agile environments.
• Background in TypeScript, Express.js, Jest, or related technologies.
• Swift or Kotlin experience for mobile development.
• A natural curiosity for new scripting languages, frameworks, and emerging technologies.
• A full-stack personal project built end-to-end with AI tools, demonstrating hands-on comfort with AI-augmented development workflows.
• Non-traditional background welcome: some of our strongest engineers transitioned into tech from entirely different careers. We care about what you can do, not where you started.

Compensation

• Total Compensation: Competitive salary with a range of $80,000-$120,000 per year, flexible for the right candidate.
• Comprehensive benefits package, including dental care, vision care, wellness program, and paid time off.

Why Join Speer Technologies?

• Ship From Day One: Every engineer at Speer pushes code to production in their first week. This is not a place where you'll wait months to make an impact.
• Growth & Ownership: Take on real responsibilities as the company scales. Your contributions are visible and valued.
• Innovation & Speed: Work in a fast-paced startup environment where no two days are the same and creative problem-solving is the norm.
• Inclusive Culture: Join a team that values diverse backgrounds, open-minded thinking, and a spirit of collaboration.
