About the Role

Onebrief is hiring a Senior Solutions Architect to lead and support the deployment of our operational planning platform across secure U.S. military environments. The Senior Solutions Architect is a hands‑on, customer‑facing architect who leads solution design, validates feasibility through prototypes, and guides successful implementations. This role bridges pre‑sales discovery and post‑sales delivery, aligning technical decisions with business outcomes across security‑sensitive and enterprise environments.

About You

Architects are part of our Infrastructure and Security organization and we work across the company to solve hard challenges that unlock new markets and use cases. Successful candidates are much more than just technical experts; they display systems thinking and customer empathy to communicate technical trade-offs clearly and align outcomes. They collaborate in an async‑first way; document their work, decisions, and tradeoffs; and collaborate strongly across sales, product, and engineering orgs. Lastly, they raise the bar for security and operational excellence.

What You'll Do

• Own regional, account, or program‑level solution architecture from discovery through delivery, including reference designs, sequence diagrams, and data contracts

• Lead technical discovery, requirement shaping, and success criteria definition with customers and partners

• Build credible prototypes and integration proofs to de‑risk performance, security, and interoperability

• Influence product roadmaps with field feedback, patterns, and reusable components

• Create clear architecture artifacts: threat models, deployment topologies, runbooks, and migration plans

• Guide customers on scalability, reliability, cost, and operability trade‑offs

• Mentor engineers and partner teams through design reviews, pairing, and office hours

• Support opportunity cycles with demos, RFx responses, and executive‑level narratives

• Champion best practices for cloud, data, networking, security, and compliance

What We Look For

• 8+ years in specific technology domains such as software development, cloud computing, systems engineering, infrastructure, security, networking, or data and analytics

• 5+ years designing and implementing applications and/or infrastructures, or consulting on the same

• 10+ years of IT development or implementation/consulting experience in software or Internet industries

• 3+ years in technology or software sales contexts supporting pre/post‑sales architecture

• Active Top Secret Clearance required; SCI eligibility is a plus.

Preferred Qualifications

• Experience with enterprise and regulated deployments, including FedRAMP, STIGs, or similar frameworks

• Proficiency designing with modern cloud and data stacks such as Kubernetes, containers, CI/CD, observability, Redis, streaming (Kafka/Redpanda), object storage (S3‑compatible), and relational stores (PostgreSQL)

• Familiarity with modern web application patterns, real‑time collaboration, maps/geo, and data visualization

• Strong integration background across identity (SSO/OIDC/SAML), networking (VPC peering, private link), and API design

• Demonstrated ability to create architecture documentation and present to executive and deeply technical audiences

• Comfort with hands‑on prototyping using TypeScript/Node/React or similar
