Lead Software Architect designing multi-tenant cloud-native .NET platforms at Computrition. Collaborating with teams to ensure HIPAA compliance and effective technical architecture.
Responsibilities
Act as the architecture decision maker: own ADRs and design governance, set standards, and make build/buy/vendor choices that balance speed, cost, and risk.
Communicate with clarity: translate trade‑offs for executives and customers; facilitate high‑signal design reviews and whiteboard sessions.
Own the architecture for a greenfield/cloud‑native .NET platform on AWS; produce reference architectures, threat models, and deployment blueprints.
Design for multi‑tenant SaaS: tenant isolation, data partitioning strategies, rate limiting, per‑tenant configuration, and cost/usage observability.
Model core domains & APIs using domain‑driven design; define contracts, versioning, and API gateways; champion consistency and evolvability.
Select & integrate AWS services (ECS/EKS or Lambda, API Gateway/ALB, S3/CloudFront, RDS/Aurora PostgreSQL, ElastiCache/Redis, SQS/SNS or RabbitMQ, OpenSearch, KMS, Secrets Manager, CloudWatch, IAM).
Data architecture for PostgreSQL: schema and migration strategy, performance (indexes/partitioning), read/write scaling, and HA/DR (backups, replicas, RTO/RPO).
Frontend architecture with React + Fluent UI: component library strategy, accessibility (WCAG), performance budgets, and SSR/edge delivery where appropriate.
Security‑by‑design: encryption in transit/at rest, least‑privilege IAM, SSO (OIDC/SAML), secret rotation, audit trails, and secure SDLC gates.
HIPAA alignment: partner with Security/Compliance on safeguards (administrative, physical, technical), logging/audit requirements, and evidence for SOC 2/HITRUST.
Observability: implement distributed tracing/metrics/logging (OpenTelemetry), golden signals, dashboards, and actionable alerting.
DevEx and velocity: CI/CD pipelines, Infrastructure as Code (Terraform or AWS CDK), environment strategy (feature envs/preview apps), and automated quality gates.
Mentor and lead engineers through design reviews, pairing, and coaching; foster a high‑trust, learning‑oriented culture.
Requirements
Exceptional communication and influence skills: clear written/verbal storytelling for executives, customers, and engineers; facilitation of workshops and whiteboard sessions.
8+ years building production web platforms; 3+ years in an architect/tech‑lead role owning system design and decisions.
AWS expertise designing secure, highly available, cost‑aware services (VPC/networking, IAM/KMS, API Gateway/ALB, ECS/EKS or Lambda, RDS/Aurora PostgreSQL, CloudWatch).
Expert in C#/.NET (ASP.NET Core) and modern API patterns (REST/JSON; bonus: gRPC).
Proficiency with PostgreSQL (schema design, performance tuning, migrations, backup/restore/replication).
Frontend proficiency in React; familiarity with Fluent UI and accessibility best practices.
Deep understanding of multi‑tenant SaaS patterns, distributed systems, and event‑driven architectures.
Track record implementing observability, CI/CD, and IaC in production.
Security fundamentals: OAuth2/OIDC, TLS, least‑privilege IAM, secure coding; working knowledge of HIPAA technical safeguards.
Benefits
Occasional travel requirements to Bedford MA office for occasional in‑person whiteboard sessions
