How to Apply for Staff Deep Learning Engineer

at Hayden AI

🏢 About Hayden AI

Hayden AI is at the forefront of using AI to transform urban transit and sustainability. Their mission to make cities safer and more efficient through computer vision and deep learning is both impactful and technically challenging. As a startup, they offer the agility to innovate rapidly while tackling real-world problems at scale.

About This Role

As a Staff Deep Learning Engineer, you will lead the end-to-end delivery of perception projects from design to production, shaping how transit systems perceive the world. Your work directly influences product roadmap and technical investments, with significant mentorship responsibilities that amplify your impact across the team.

💡 A Day in the Life

You'll start by reviewing model performance metrics from the previous day's edge deployments, then lead a standup with the perception team. Afternoons involve deep-dive design reviews with Platform engineers on model optimization, followed by mentoring a junior engineer on training pipeline improvements. You'll end the day contributing to the next quarter's roadmap by evaluating new sensor modalities.

🎯 Who Hayden AI Is Looking For

  • Proven track record of deploying ML models in production for 8+ years, with experience as a tech lead or staff engineer in a fast-paced environment.
  • Deep expertise in at least two perception verticals (e.g., object detection, segmentation, tracking, sensor fusion) with hands-on ability to optimize models for edge deployment.
  • Strong cross-functional communicator who can align Deep Learning, Platform, and Product teams on technical approaches and drive consensus.
  • Thrives in a startup setting—comfortable with ambiguity, prioritizes impact, and mentors junior engineers through code reviews and design feedback.

📝 Tips for Applying to Hayden AI

1

In your resume, explicitly highlight projects where you led perception model delivery from research to production, including metrics on latency, accuracy, and scalability.

2

Prepare a brief technical summary of one perception vertical you own, describing trade-offs in model architecture, training data, and edge deployment constraints.

3

Showcase your mentorship experience with specific examples: code review strategies, design doc feedback, or onboarding processes you improved.

4

Tailor your cover letter to mention Hayden AI's mission—connect your work to safer transit and urban sustainability.

5

Be ready to discuss how you've prioritized technical investments in past roles, aligning with product and business goals.

✉️ What to Emphasize in Your Cover Letter

['Emphasize your end-to-end ownership of perception projects and ability to drive alignment across teams.', "Highlight specific perception verticals you've mastered and your experience with edge deployment.", "Mention how you've mentored engineers and contributed to team roadmap decisions.", "Express genuine interest in Hayden AI's mission and how your skills can advance safer, more efficient transit."]

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read about Hayden AI's flagship product: automated bus lane enforcement and how their perception system works.
  • → Look into their blog or tech talks on computer vision challenges in urban environments.
  • → Understand their tech stack: likely PyTorch/TensorFlow, ONNX/TensorRT for edge, and cloud infrastructure.
  • → Check recent news or case studies about their impact on transit efficiency and sustainability.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk through a perception project you led from design to production—challenges, decisions, outcomes.
2 How would you approach optimizing a model for edge deployment given latency, memory, and accuracy constraints?
3 Describe a time you had to align cross-functional teams on a technical approach. How did you handle disagreements?
4 How do you evaluate and prioritize new technical investments for the deep learning roadmap?
5 Given a scenario of a perception failure in production, how would you debug and mitigate it?

⚠️ Common Mistakes to Avoid

  • Don't be vague about your role in projects—use 'I led' instead of 'we did' to show ownership.
  • Avoid generic ML knowledge; focus on perception-specific expertise and production deployment.
  • Don't neglect the startup aspect—emphasize comfort with fast pace, ambiguity, and cross-functional collaboration.
