68 / 100 honest fit
Daniel is a strong backend fit: he builds and maintains scalable services, APIs, and automation in Python/C++ on AWS, does deep cross-team root-cause analysis, and already mentors junior engineers — the core of what a Senior Core Platform engineer does. The main gap is scale and stack context: his production API experience is in regulated medical-device and self-hosted Flask environments rather than internet-scale, high-QPS consumer platforms, and Reddit's stack (Go, GraphQL, very large distributed systems) isn't reflected in his resume.
Tailored resume highlights
- Build and maintain scalable backend services and APIs that deliver reliable data at the source-of-truth layer for connected devices, with a focus on correctness and system performance.
- Serve as a technical mentor and coach to junior engineers on API design, automation, and CI/CD workflows — sharing best practices across the team.
- Lead root-cause analysis of complex, cross-team production issues, reproducing rare defects in-house and driving resolution across multiple engineering teams.
- Design and maintain Python/C++ test and automation frameworks validating real-time communication protocols and high-throughput data flows, integrated into Jenkins CI/CD for reproducible, reliable delivery.
- Implement AWS-based services (Lambda, S3, DynamoDB) supporting scalable data processing and monitoring, with strong emphasis on reliability and test coverage.
"Why this company?" (draft — personalize before sending)
Reddit's Core Platform team owns the APIs and data models that are the source of truth for posts and comments at massive scale — that's exactly the kind of reliability-first backend work I've built my career around. In medical devices, correctness isn't optional, and I've carried that same standard into the dozen-plus production services I run myself. I also like that this role is explicitly about mentoring and technical coaching, which is where I already spend a lot of my time. Building the APIs millions of requests depend on, where getting it right actually matters, is the kind of problem I want to work on.
Cover letter (review before sending)
Dear Reddit Hiring Team,
I'm applying for the Senior Software Engineer, Core Platform role. The heart of this job — owning the APIs and data models that are the source of truth for posts, comments, and listings — maps directly to how I've spent my career: building and maintaining scalable backend services and APIs where reliability and correctness are hard requirements, not nice-to-haves.
At Medtronic I build backend services and Python automation frameworks integrated into CI/CD, implement AWS services (Lambda, S3, DynamoDB) for scalable data processing, and lead root-cause analysis of complex issues across multiple teams. I also mentor junior engineers on coding, automation, and CI/CD practices — the technical-coaching dimension this role emphasizes. On my own, I've shipped roughly a dozen production Flask services end-to-end, so I understand what it takes to keep live, public systems healthy.
I'd welcome the chance to bring that reliability-first, mentor-oriented approach to the APIs millions of Reddit requests depend on.
Sincerely,
Daniel Maynard
