How to Apply for Senior Fullstack Engineer

at Halter

🏢 About Halter

Halter is unique as it combines agricultural technology with IoT hardware to directly improve farming sustainability and animal welfare. Working here means contributing to tangible environmental impact through technology that helps farmers monitor and manage their herds more efficiently. The company's mission-driven focus on healthier cows and more productive farms creates meaningful work beyond typical tech roles.

About This Role

This Senior Fullstack Engineer role involves designing and delivering scalable systems for both web and mobile applications that directly support farmers' daily operations. You'll make architectural decisions across the entire stack while collaborating closely with hardware, data, and product teams to ship features that impact agricultural productivity. The role specifically emphasizes applying AI tools to improve development velocity while maintaining system simplicity.

💡 A Day in the Life

A typical day involves collaborating with hardware and data teams to design APIs that ingest sensor data from farm equipment, then implementing both backend services and frontend interfaces that help farmers visualize herd health metrics. You might spend the morning optimizing a data pipeline for real-time cow monitoring, then work with the design team in the afternoon to improve the mobile app's user experience for farmers in the field.

🎯 Who Halter Is Looking For

  • Has production experience designing complex full-stack systems that include both backend services and web/mobile applications
  • Possesses deep technical expertise across modern web/mobile apps, REST APIs, distributed systems, and event-driven services
  • Has hands-on experience with both relational and non-relational databases in cloud environments (AWS experience is particularly valuable)
  • Has backend development experience with Node.js or Go, especially in systems that integrate with hardware or IoT devices

📝 Tips for Applying to Halter

1

Highlight specific examples where you've designed full-stack systems that scaled in production, particularly those involving both web/mobile interfaces and backend services

2

Demonstrate experience with event-driven architectures or distributed systems, as Halter's farm monitoring systems likely involve real-time data processing

3

Showcase any experience integrating software with hardware systems, as this role works closely with Halter's hardware team

4

Include examples of applying AI tools or automation to improve development velocity while maintaining code quality

5

Emphasize experience with both SQL and NoSQL databases in cloud environments, with specific AWS services if possible

✉️ What to Emphasize in Your Cover Letter

['Your experience designing and delivering production full-stack systems, especially those that scaled to handle significant user loads', 'Specific examples of working across the entire technology stack and making architectural decisions that impacted both frontend and backend', 'Experience collaborating with cross-functional teams (particularly hardware, data, or product teams) to ship high-impact features', "How you've applied technology to solve real-world problems, ideally in domains involving physical systems or data-intensive applications"]
