68 / 100 honest fit
Daniel brings strong backend, AWS (Lambda/S3/DynamoDB), and CI/CD experience plus a reliability-first mindset forged in safety-critical medical-device software — directly relevant to building and scaling Stytch's authentication infrastructure, and his Go2F work on secure authenticated APIs maps to the identity/auth domain. The honest gap is that his title has been software/test engineer rather than a dedicated infrastructure/SRE role, so he has limited demonstrated depth in specific platform tooling (e.g., Kubernetes, Terraform, Go) that this infra position may weight heavily.
Tailored resume highlights
- Built and optimized backend services and validation pipelines for connected devices, ensuring reliable data delivery and system performance under strict correctness requirements.
- Implemented AWS-based solutions (Lambda, S3, DynamoDB) supporting scalable data processing and monitoring for production systems.
- Developed Python automation frameworks integrated into Jenkins CI/CD pipelines, enabling reproducible deployments and accelerating feature delivery.
- Led root-cause analysis of complex field-found issues, reproducing rare defects in-house and driving cross-team resolution — core to keeping infrastructure reliable at scale.
- Implemented secure C and Python APIs with authentication and data access control for scalable IoT endpoint integration (Go2F), directly relevant to identity/auth infrastructure.
"Why this company?" (draft — personalize before sending)
Stytch is authentication infrastructure, and that's where two threads of my background meet: at Go2F I built secure, authenticated APIs with data access control, and at Medtronic I've spent years on backend services where reliability and correctness are requirements, not nice-to-haves — exactly the standard auth infrastructure demands. I also independently ship and operate hardened production services (rate limiting, monitoring, self-healing watchdogs) using Claude Code daily, so I care about developer-facing tools that stay dependable. Building and scaling Stytch's core product is the kind of reliability-critical infrastructure work I want to do.
Cover letter (review before sending)
Dear Twilio / Stytch team,
I'm applying for the Senior Infrastructure Engineer role on Stytch. I'm a Senior Software Engineer at Medtronic where I build and operate backend services, AWS-based solutions (Lambda, S3, DynamoDB), and Python automation frameworks wired into CI/CD — with reliability and correctness treated as requirements, not features, because the software runs on connected medical devices. That discipline, plus deep root-cause analysis of rare, cross-team defects, is what I'd bring to scaling Stytch's core product.
The authentication domain also connects to earlier work: at Go2F I implemented secure C and Python APIs with authentication and data access control for scalable endpoints. Outside of work, I ship and operate production Flask services on a self-hosted Linux server — hardened endpoints, rate limiting, monitoring, and self-healing watchdogs — using Claude Code as a core part of my workflow, so I understand what it takes to keep live services healthy.
I'd welcome the chance to contribute to Stytch's infrastructure.
Sincerely,
Daniel Maynard
