About the Role

Join our engineering team as a Senior Software Engineer and play a crucial role in building the solutions that power manufacturing shops. You'll work across the full stack — designing backend services and building rich, user-facing experiences — and take ownership of meaningful slices of the product. You'll work with a modern tech stack, solve complex problems, mentor other engineers, and help shape how we adopt AI across our engineering workflow. This role is ideal for engineers who pair technical excellence with a drive for customer impact.

Who You Are

• Technically Excellent: You combine deep technical skill with a passion for delivering value to customers, and you build scalable, maintainable systems that meet real-world needs.
• Customer-Driven Innovator: You thrive in environments that encourage innovation and you're driven to build products that make a difference.
• AI-Fluent with Good Judgment: You use AI tools to multiply your output while owning the quality, reliability, and security of what you ship, and you know when to lean on them and when not to.
• Lifts the Team: You help the engineers around you get better, sharing what you know and raising the bar through code review and mentorship.

Why You'll Love Working Here

• Customer-Centric Focus: We put our customers at the center of everything we do. Your work will directly contribute to their success.
• Modern Technology: We work across a modern stack — Python (Django and FastAPI), TypeScript and React, PostgreSQL, and AWS — and we're actively investing in how AI can accelerate our software development lifecycle.
• Complex and Meaningful Challenges: Our software is used in critical industries like aerospace and defense, requiring robust, secure, and scalable solutions. You'll be solving problems that truly matter.
• Collaborative and Inclusive Culture: We believe that diverse teams build better products. Our culture emphasizes collaboration, continuous learning, and mutual respect.
• Growth Opportunities: You'll mentor others, influence technical direction, and grow with us as we scale.

What You'll Do

• Build Across the Stack: Design, implement, and maintain scalable, high-performance features spanning Python backends and React frontends.
• Design APIs: Develop robust, secure, versioned APIs that enable seamless integration and data access.
• Apply AI Across the SDLC: Use AI tools fluently across the software development lifecycle — planning, coding, testing, review, and documentation — develop effective patterns for AI-assisted work, and share what works with the team.
• Solve Complex Problems: Tackle deeply technical challenges across the stack, balancing trade-offs to deliver secure, compliant solutions that meet our customers' needs.
• Champion Engineering Excellence: Advance our practices — testing, observability, code review, and context-first documentation — so our codebase stays high-quality, performant, and legible to both humans and AI agents.
• Mentor and Grow Talent: Share your expertise with less experienced engineers, fostering a culture of continuous learning.
• Collaborate Across Teams: Work closely with designers, product managers, and other engineers to deliver products that exceed customer expectations.

What You'll Bring

• 5+ years of experience delivering impactful software, with strong object-oriented fundamentals.
• Proficiency in a modern backend web stack, such as Python/Django or FastAPI, Node/Express, or Java/Spring.
• Hands-on frontend experience with TypeScript and React, building and maintaining production user interfaces.
• Hands-on experience with AWS, designing and deploying scalable, resilient cloud architectures.
• Experience with relational and non-relational databases, with a clear sense of when to use each.
• Strong experience with API design, development, documentation, and versioning.
• Expertise building and deploying applications with Docker and CI/CD tooling like Jenkins.
• Practical experience using AI coding tools in a real engineering workflow, with sound judgment about where they help and where they don't.
• Strong communication skills, conveying complex technical concepts to technical and non-technical stakeholders.

Why Join Us?

• Impactful Work: Your contributions will power industries critical to our society and economy, making a real difference in the world.
• Continuous Learning: We invest in our people and offer opportunities to learn, grow, and advance their careers.
• Supportive Culture: Our team is our greatest asset, and we foster an environment where everyone can thrive.
