About the Backend Engineer role
Backend Engineers build the server-side logic, APIs, and data layer that power an application — reliability and performance under load are the core job, often invisible to end users when done well.
Skills you'll need

SUMMARY
Backend engineer with 6 years building and operating high-throughput APIs and data services. Deep experience with PostgreSQL at scale and on-call ownership for production systems serving millions of requests per day.
EXPERIENCE
Backend Engineer, Ridgeline Systems — Remote | 2021–Present
• Own the payments API handling 4M+ requests/day at 99.98% uptime over the past year
• Redesigned the database sharding strategy, cutting p99 query latency from 1.2s to 180ms
• Built the on-call runbook and incident postmortem process now used across 3 engineering teams
Backend Engineer, Copperleaf Technologies — London, UK (Hybrid) | 2018–2021
• Built the notifications service (Node.js, RabbitMQ) processing 2M+ events/day
• Migrated a monolithic Rails app's core API to Go microservices, reducing infra costs by 30%
• Introduced structured logging and distributed tracing, cutting mean incident-diagnosis time from 40 to 12 minutes
SKILLS
Node.js, Go, PostgreSQL, Redis, RabbitMQ, Docker, Kubernetes, AWS, distributed systems, incident response
EDUCATION
B.S. Computer Science, University of Ghana | 2017

Sample cover letter for Backend Engineer
Same idea — a structure to learn from, not to send as-is.
Dear Hiring Manager,
I'm applying for the Backend Engineer role because the scale you're describing — millions of requests a day with real reliability requirements — is the kind of problem I've spent my career on.
At Ridgeline Systems, I own our payments API at 4M+ requests a day and 99.98% uptime, and I redesigned our database sharding strategy to bring p99 latency down from 1.2 seconds to 180 milliseconds. Earlier, at Copperleaf, I led the migration of our core API from a Rails monolith to Go microservices, which cut infrastructure costs by 30% while improving reliability.
I take on-call seriously and enjoy the postmortem process as much as the build — I built the incident runbook three teams at Ridgeline still use. I'd welcome the chance to talk through your current architecture.
Sincerely,
Kwame Asante

- •Walk me through how you'd design a system that needs to handle a large volume of requests reliably.
- •Tell me about a production incident you were involved in. What was the root cause and fix?
- •How do you approach database schema design when requirements are still evolving?
- •Describe a time you had to make a tradeoff between shipping speed and technical debt.
- •What's your approach to on-call, and how do you handle being paged for something you don't immediately understand?
