How to Apply for Senior Software Engineer - Platform

at Choco

🏢 About Choco

Choco is a fast-growing startup that tackles food waste and supply chain inefficiencies in the restaurant industry. Their platform connects restaurants and suppliers, reducing waste and promoting sustainability—a mission that resonates with engineers who want their work to have a tangible environmental impact.

About This Role

As a Senior Software Engineer on the Platform team, you'll design and build the foundational backend systems that all product teams rely on. Your work will directly improve developer velocity, system reliability, and scalability, enabling Choco to expand globally while maintaining high performance.

💡 A Day in the Life

You’ll start by reviewing dashboards and alerts for the platform services you own, then attend a stand-up with product teams to discuss blockers. The rest of the day might involve designing a new API for a shared service, writing code to improve CI/CD pipeline speed, or pairing with a product engineer to troubleshoot a performance issue.

🎯 Who Choco Is Looking For

  • You have 5+ years building and operating backend systems at scale, with hands-on experience in distributed systems, microservices, and event-driven architectures.
  • You’ve owned complex technical problems end-to-end—from discovery to deployment and production operations—and can demonstrate sound engineering judgment on when to simplify vs. redesign.
  • You’re passionate about developer experience and have built reusable tooling, frameworks, or APIs that accelerated other teams.
  • You thrive in a remote-first, collaborative environment and are comfortable partnering closely with product engineering teams to unblock them.

📝 Tips for Applying to Choco

1

Tailor your resume to highlight platform engineering work (e.g., building internal tools, shared services, or infrastructure) rather than just product features.

2

In your cover letter or resume, explicitly mention experience with event-driven architectures and cloud infrastructure (e.g., AWS, Kubernetes, Kafka).

3

Quantify the impact of your platform work—e.g., 'Reduced deployment time by 40%' or 'Enabled 3 product teams to ship faster with a new API gateway.'

4

Show that you understand the trade-offs between building vs. buying, and include examples of when you chose to simplify rather than over-engineer.

5

Research Choco’s engineering blog or tech stack (they use Go, TypeScript, AWS, and Kubernetes) and mention familiarity or interest in those technologies.

✉️ What to Emphasize in Your Cover Letter

['Emphasize your experience designing scalable backend systems and shared services that improved developer productivity.', 'Highlight your ability to operate distributed systems in production, including monitoring, incident response, and reliability improvements.', 'Connect your past work to Choco’s mission—e.g., how your platform contributions enabled faster feature delivery that could reduce food waste.', 'Mention your collaborative approach and experience working cross-functionally with product teams to solve technical bottlenecks.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read Choco’s engineering blog posts (if any) or their tech stack overview to understand their current tools and challenges.
  • → Understand the restaurant supply chain domain—how Choco’s platform connects buyers and suppliers, and where platform bottlenecks might occur.
  • → Look at Choco’s public GitHub or open source contributions (if any) to see their engineering culture and code quality.
  • → Check recent news or funding rounds to understand Choco’s growth stage and scale—this helps tailor your experience to their needs.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Design a scalable event-driven system for real-time order updates between restaurants and suppliers.
2 How would you improve the developer experience for a team struggling with slow CI/CD pipelines?
3 Describe a time you had to decide between refactoring a legacy system vs. building a new one. What trade-offs did you consider?
4 How do you ensure reliability and observability in a microservices architecture? Give specific tools or practices.
5 Walk through how you would handle a production incident involving a platform service that causes cascading failures.

⚠️ Common Mistakes to Avoid

  • Don’t focus solely on product features; this is a platform role, so emphasize infrastructure, APIs, and tooling.
  • Avoid vague descriptions of scale—be specific about traffic, data volume, or number of services you managed.
  • Don’t neglect the 'operate' part of the job; failing to mention production ownership, on-call, or observability can hurt your application.
