Software Engineer, Backend Infrastructure

At Squint, we're building technology that matters. While many tech companies focus on digital-first industries, we've set our sights on empowering the 80% of the global workforce that keeps our world running: frontline manufacturing operators. From soda cans to tires, toothpaste to chocolate bars, chips to napkin holders, these are the people who build the things you touch and see every single day.

Squint delivers critical knowledge to frontline workers exactly when and where they need it. Our platform transforms manufacturing operations by putting AI and AR capabilities directly at workers' fingertips, creating what we call "agentic manufacturing" – where every team member has the power to make informed decisions in real-time using practical, applied artificial intelligence tools.

Our technology serves Fortune 500 leaders across Automotive, Consumer Packaged Goods, and Life Sciences industries. These companies trust Squint to capture and activate their essential operational know-how, resulting in measurable improvements: reduced downtime, minimized waste, and optimized productivity at scale

.

We build consumer-grade software that delivers enterprise-grade results on familiar devices: phones and tablets. By combining cutting-edge innovation with deep customer insights, we create tools that feel intuitive while transforming how physical production environments operate.

We raised a $40m Series B at a $265m valuation and are backed by elite investors including Sequoia Capital, Menlo Ventures, TCV and The Westly Group. Our co-founders have been recognized on Forbes' 30 Under 30 for Manufacturing and Industry, and Fast Company named us one of the most innovative augmented and virtual reality companies of 2025.

When you join Squint, you're not just building another app – you're creating technology that improves daily work life for people who manufacture the products our world depends on. It's meaningful work with visible impact.

Squint is hiring a Software Engineer, Backend Infrastructure. You’ll architect and scale the core backend systems that power our platform, improving reliability, performance, and developer velocity as we grow. This is a high-ownership role where you’ll shape foundational infrastructure, influence technical direction, and help build a culture of craftsmanship and impact.

Must be comfortable working out of our Downtown SF office Monday through Friday.

• Real-world impact. You’ll build systems where reliability and performance genuinely matter for the world’s largest manufacturers.

• High ownership, high craftsmanship. As an early engineer, you’ll influence core architecture and technical direction while focusing on simple, elegant, well-architected systems.

• Foundational infrastructure. Our stack is working but still maturing (Terraform, observability, streaming, etc.). You’ll define how Squint’s backend infrastructure is designed, built, and operated.

• Broad engineering scope. You’ll work across infrastructure and backend product surfaces—from build/test/deploy loops and cloud primitives to new capabilities like video streaming and observability—gaining exposure to a wide range of systems and problems.

• Scale and harden Squint’s backend infrastructure: compute, networking, data stores, and core services.

• Build and evolve our observability stack (metrics, logs, tracing, alerting) to improve uptime and debuggability.

• Improve CI/CD pipelines and release processes to support fast iteration with high confidence.

• Drive reliability engineering practices: incident response, postmortems, SLOs, and prevention-focused tooling.

• Mentor and uplevel the team on infrastructure best practices, performance tuning, and operational excellence.

• Partner with Engineering leadership on system design and technical strategy as we grow.

• Collaborate cross-functionally to ensure infrastructure supports product needs and compliance requirements.

• Flexibly jump in wherever needed–we’re a startup!

• 5+ years of experience as a Software Engineer with a strong focus on infrastructure, platform, or DevOps.

• Experience designing, scaling, and operating production backend systems on a major cloud provider (GCP, AWS, or Azure).

• Hands-on experience with core infrastructure tooling such as Docker, Kubernetes, Terraform, and modern CI/CD.

• Strong observability instincts and familiarity with monitoring/logging stacks (e.g., Datadog, Prometheus, Grafana).

• Proficiency in backend languages such as Python, Node.js, or Go.

• Comfort across data systems, including relational (PostgreSQL/MySQL) and non-relational (MongoDB/Firestore) databases.

• High energy, clear communication, curiosity, and customer empathy, paired with a collaborative, high-ownership mindset.

Based out of our office in San Francisco, we love the energy of in-person collaboration.
