Lead Architect

Join to apply for the Lead Architect role at Computrition, Inc. Lead Software Architect (Decision Maker) – Cloud‑Native .NET (AWS, Healthcare/HIPAA) Computrition – Jonas Software ( Location Remote U.S.; preferred location is the greater Boston area. Occasional travel to Bedford, MA office for in‑person whiteboard sessions (≤1–2 days per quarter). Team: Engineering Type: Full‑time About The Role We’re seeking a hands‑on Lead Software Architect who will serve as the decisive technical leader to design and evolve a secure, multi‑tenant, cloud‑native platform built on .NET in AWS. Our stack includes PostgreSQL, React with Fluent UI, and modern DevSecOps practices. As the architecture decision maker, you will define the target state, document key trade‑offs (ADRs), and communicate clearly with executives and engineers. You will partner with Security/Compliance to meet HIPAA requirements while guiding teams through delivery with simplicity, scalability, and cost‑awareness. What You’ll Do Own ADRs and design governance; set standards and make build/buy/vendor choices that balance speed, cost, and risk. 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). Design PostgreSQL schema and migration strategy; performance tuning (indexes/partitioning), read/write scaling, HA/DR (backups, replicas, RTO/RPO). Frontend architecture with React + Fluent UI: component library strategy, accessibility (WCAG), performance budgets, SSR/edge delivery. Security‑by‑design: encryption in transit/at rest, least‑privilege IAM, SSO (OIDC/SAML), secret rotation, audit trails, secure SDLC gates. HIPAA alignment: partner with Security/Compliance on safeguards (administrative, physical, technical), logging/audit requirements, evidence for SOC 2/HITRUST. Reliability & performance: SLOs/SLIs, capacity planning, load testing, chaos/resiliency patterns (circuit breakers, timeouts, backoff, idempotency). Observability: implement distributed tracing/metrics/logging (OpenTelemetry), golden signals, dashboards, actionable alerting. DevEx and velocity: CI/CD pipelines, Infrastructure as Code (Terraform or AWS CDK), environment strategy (feature envs/preview apps), automated quality gates. Mentor and lead engineers through design reviews, pairing, coaching; foster high‑trust, learning‑oriented culture. Required Qualifications 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. Nice to Have Experience with HL7 v2/FHIR integrations, EHR ecosystems (Epic/Cerner), or interface engines (e.g., Mirth Connect). HITRUST/SOC 2 program experience (controls, evidence, audit readiness). Messaging/streaming: RabbitMQ, SQS/SNS, or Kafka; patterns for exactly‑once‑effect via idempotency. Container orchestration (EKS or ECS), service meshes, and zero‑trust networking. Caching (Redis/ElastiCache), search (OpenSearch/Elasticsearch), reporting/analytics patterns. Performance engineering (load modeling, flamegraphs, memory/GC tuning in .NET). Experience with Next.js or SSR/edge rendering for React. What Success Looks Like (6–12 Months) A vetted reference architecture with ADRs, diagrams, and guardrails adopted across teams. Production‑ready multi‑tenant foundation with automated provisioning and per‑tenant telemetry. Secure, observable MVP deployed to AWS with defined SLOs and error budgets. CI/CD delivering fast, safe releases (blue/green or canary), with automated quality gates. Evidence mapped to HIPAA/SOC 2/HITRUST controls for key services. Work Style & Collaboration Remote‑first with very limited in‑person whiteboard sessions (≤1–2 days per quarter or as needed with advance notice); travel supported. Partner with Product, Security/Compliance, and Customer Success; engage with key customers and clinical stakeholders when needed. Lead design reviews and coach teams; prefer simple, evolvable solutions over speculative complexity. Equal Opportunity We’re an equal‑opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. Interested? Send your resume or portfolio of architecture work (diagrams, ADRs, talks) and let’s talk.
