68 / 100 honest fit
Daniel is a strong backend/infrastructure fit: he builds Python backend services and automation frameworks integrated into Jenkins CI/CD, works hands-on with AWS (Lambda, S3, DynamoDB), and comes from safety-critical medical-device software where reliability and correctness are hard requirements — directly matching Trust Infra's emphasis on reliable, secure, automated guardrails. The main gap is that his resume doesn't show direct Kubernetes, secrets management, or auth/cryptography/certificate experience central to this specific security-infrastructure team, so he'd be ramping into that domain.
Tailored resume highlights
- Built and optimized backend services and validation pipelines for connected devices, prioritizing reliable data delivery, correctness, and system performance in a safety-critical, regulated environment.
- Developed Python automation frameworks integrated into Jenkins CI/CD, enabling reproducible, fault-tolerant deployments and reducing deployment errors — the kind of guardrails and developer-experience automation that support safe, rapid delivery.
- Implemented AWS-based solutions (Lambda, S3, DynamoDB) for scalable data processing and monitoring across cloud and embedded components.
- Implemented secure C and Python APIs with authentication and data access control for IoT endpoints, supporting scalable, controlled integration.
- Led root-cause analysis of complex, rare field-found defects, reproducing them in-house and driving cross-team resolution — deep debugging where reliability is a requirement, not a feature.
"Why this company?" (draft — personalize before sending)
Affirm's Trust Infra team is doing what I already care about: embedding reliability and security from provisioning through deployment and building automation guardrails so teams can ship safely and fast. That maps directly to my work — CI/CD automation frameworks, AWS backend services, and secure APIs — and to my background in regulated medical-device software, where correctness isn't optional. I also spend a lot of my own time building and operating production services end-to-end, so the developer-experience and safe-delivery mission genuinely resonates with how I like to work.
Cover letter (review before sending)
Dear Affirm Hiring Team,
I'm applying for the Senior Software Engineer, Backend (Infrastructure) role on the Trust Infra team. My background is backend and infrastructure engineering where reliability is non-negotiable: at Medtronic I build Python backend services and automation frameworks for connected medical devices, integrate them into Jenkins CI/CD for reproducible, fault-tolerant deployments, and implement AWS solutions (Lambda, S3, DynamoDB) for scalable data processing. Coming from regulated, safety-critical software, I treat correctness and reliability as requirements, not features — which maps closely to a team that embeds security from provisioning to deployment and builds guardrails for safe, rapid delivery.
I've also led root-cause analysis of rare, cross-team defects and built secure APIs with authentication and access control, and I mentor engineers on automation and CI/CD practices. I'm honest that Kubernetes and secrets/crypto tooling would be a ramp for me, but I learn systems fast and care deeply about the developer experience automation this role centers on.
Thank you for your consideration.
Daniel Maynard
