Asepha is an AI healthcare startup with offices in Toronto and New York, building AI tools that automate and streamline medication workflows across the global pharmacy landscape. Backed by more than $4 million in funding and trusted by Fortune 50 healthcare organizations, we’re scaling quickly, and we need an engineer who can turn bold ideas into fast, reliable production systems.

We are seeking a talented and innovative senior software engineer in Toronto to join our growing team. As one of our early hires, you'll play a critical role in shaping our engineering efforts, making key architectural decisions, and writing code to expand our AI product line. You will play a pivotal role in balancing speed of execution with product quality, and have the opportunity to wear multiple hats, from frontend and backend development to devops and customer interactions. Your work will have a direct impact on improving pharmacy workflows and health outcomes.

Role and Responsibilities:

You’ll own critical pieces of our AI platform, from low‑latency inference services to integrations with external pharmacy software. Day‑to‑day you’ll be:

• Designing and shipping production‑grade backend services that power our core products
• Building and maintaining event‑driven data pipelines and real‑time APIs
• Orchestrating large‑language‑model workflows, vector search, and GPU scheduling
• Hardening systems for HIPAA‑grade security, observability, and high availability
• Collaborating with pharmacists, product, and design to move from sketch to shipped feature in weeks, not quarters

Qualifications:

• Hands‑on experience with AWS or Google Cloud (EKS, Lambda, App Runner, or equivalents) and container orchestration
• Solid grasp of data stores (PostgreSQL, Redis, or columnar DBs) and streaming (Kafka, Kinesis, or NATS)
• Familiarity with LLMs or ML‑adjacent services (vector DBs, embedding pipelines, transformers)
• Track record of owning projects end‑to‑end in a fast‑moving environment
• Clear, concise communication, able to explain trade‑offs to non‑engineers
• A great communicator and team player.
• Located in Toronto, Canada.

Nice‑to‑haves

• Prior work on healthcare or fintech products with strict compliance needs
• Knowledge of eRx or healthcare data standards (FHIR, NCPDP SCRIPT)
• Front‑end chops (React/TypeScript) or DevOps tooling expertise
• Experience integrating with third‑party SaaS APIs at scale

How we work

• Hybrid office: We’re in our downtown office three days a week.
• Small, senior team, low politics, high ownership, quick shipping cadence.
• Culture built on transparency, continuous feedback, and good espresso.
• We’re a low‑ego, innovative team that moves fast, challenges ideas (not people), and supports one another.

Compensation & benefits

• Competitive compensation package including a mix of salary + stock options
• Full medical, dental, vision
• Annual professional development budget (conferences, certifications)
• Unlimited days off to maintain a healthy work-life balance
• Complimentary breakfast provided daily in the office and weekly team lunches
• Exciting opportunities for professional growth and career development
