Canada ExaCare AI Full time

We are a trailblazing health tech company on a mission to revolutionize the nursing home & post‑acute space. Our innovative AI software is transforming the admissions process and care delivery in these settings. We’ve raised $10.35M to date and are experiencing rapid growth. We are looking for a Senior Platform Engineer to join our growing team. About the Role Organizations switch to ExaCare because their admission processes are broken. They rely on multiple outdated platforms and error‑prone manual work to admit residents. This fragmentation wastes time and leads to suboptimal care and business outcomes. We are seeking a high‑ownership platform engineer to design, build, and operate our AWS serverless platform—owning the infrastructure, CI/CD, observability, and guardrails that let teams ship quickly, safely, and with confidence. What You’ll Do Own our entire platform. Build and operate AWS Lambda, Step Functions, SQS/SNS, and event‑driven workflows. Manage data runtime. Operate Aurora PostgreSQL, schema migrations, performance tuning, and connection management inside VPC. Level up CI/CD. Evolve GitLab CI pipelines, caching, test sharding, and deployment stages with safe rollouts and automated DB migrations. Strengthen security. Implement least‑privilege IAM, secrets via SSM/Secrets Manager, environment isolation, and secure VPC networking. Improve observability. Standardize logging/metrics/tracing with CloudWatch and Lumigo; define SLOs, alerts, and on‑call runbooks. Optimize costs and performance. Tune concurrency, batch sizes, and runtimes; right‑size Aurora and Redis usage; track and reduce spend. Build enabling tooling. Create golden paths, CLIs, and internal automations that remove toil and speed developer velocity. Lead operational excellence. Participate in on‑call, drive postmortems, and champion reliability best practices. Pitch in wherever the startup needs it : from shipping user‑facing features and creating APIs to writing React UI when it helps the team move faster. What You’ll Bring Bachelor’s degree in computer science or similar technical field Self‑starter who turns high‑level goals into execution plans 7+ years in platform/SRE/infrastructure roles building scalable distributed systems Hands‑on AWS serverless experience (Lambda, API Gateway, Step Functions, SQS/SNS, S3) Strong with Aurora/PostgreSQL, RDS Proxy, and SQL performance fundamentals Proven CI experience (pipelines, runners, Docker‑in‑Docker, artifacts/caching) Proficiency with the Serverless Framework, CloudFormation, and IaC best practices Solid observability skills (CloudWatch, tracing/metrics/logs, SLOs) and incident response Familiarity with Redis (ElastiCache), OpenSearch, and VPC networking Comfortable automating with TypeScript/Node, Python, and Bash Bonus: experience running LLM workloads (Modal.com/Bedrock) Benefits and Perks Competitive salary and equity in a high‑growth startup Paid time off at your discretion Optional to be fully remote or work hybrid if based in Toronto, Vancouver, or NYC Medical, dental and vision coverage Access to AI tooling: Cursor, Claude Code, Codex Great start‑up culture Referrals increase your chances of interviewing at ExaCare AI by 2x #J-18808-Ljbffr
