Position Title: Solutions Architect

Location: Remote - Colombia and Mexico

What you will be doing:

The Solution Architect is responsible for leading the technical blueprint design, cross-tenant isolation strategies, and integration architectures across the AWS cloud ecosystem supporting NexusNow, Sentinel, and upcoming portfolio applications. This role partners closely with engineering leadership, product owners, and Lean Global delivery leads to define scalable, secure, and highly maintainable architectures that strictly protect the platform's multi-tenant core while facilitating swift product growth.

The ideal candidate dictates architectural excellence, translating complex multi-tenant onboarding, pricing tier entitlements, and security perimeter demands into highly automated, robust AWS cloud topologies.

Key Responsibilities

• Lead overall solution architecture and technical engineering design activities for the multi-tenant SaaS hosting control plane.

• Translate product strategy, enterprise scaling demands, and operational challenges into robust, secure cloud blueprints.

• Define and standardize AWS-native architecture patterns, multi-tier VPC isolation rules, secure API gateway layouts, and high-velocity data processing paths.

• Partner with DevOps and Platform Engineering teams to establish implementation metrics, coding definitions, and rigorous quality metrics.

• Review, pressure-test, and sign off on platform changes impacting tenant separation boundaries, cryptography parameters, and disaster recovery profiles.

• Champion API-first paradigms, governing the schemas and validation lifecycles of runtime endpoints and identity claim token structures.

• Systematically identify technical risks, documentation gaps, runtime bottlenecks, and architectural tradeoffs, making structural recommendations visible to executive stakeholders.

• Establish structural governance practices, separating retained architectural standards from Lean-executable workloads with absolute clarity.

• Lead high-level agile planning, architectural review panels, and collaborative threat-modeling sessions.

• Provide continuous technical mentorship and architectural leadership across the scaling LATAM engineering footprint.

Required Skills & Experience

• Extensive (5+ years) experience designing and scaling complex enterprise AWS cloud topologies, ideally with explicit experience handling multi-tenant SaaS environments.

• Deep understanding of distributed architectures, including event-driven patterns, microservice interaction fabrics, connection pooling, and multi-tier data caching strategies.

• Complete mastery across key AWS platform parameters, including: Amazon Cognito (federated identity lifecycles), Amazon EKS on Fargate, Aurora PostgreSQL, CloudFront/AWS WAF edge protections, and AWS Secrets Manager.

• Deep understanding of modern identity mechanics (OIDC, SAML 2.0 federation) and structural policy enforcement models (such as CASL rules or ABAC context processing).

• Proven track record of evaluating architectural risks, diagnosing technical friction points, and prescribing systematic remediation strategies.

• Excellent technical communication and blueprint mapping skills, demonstrating full credibility when interacting with deep technical engineers, business unit heads, or executive sponsors.

Nice to Have Skills

• Direct experience leading cloud transformation initiatives or platform modernization trajectories that migrated isolated software stacks into shared platform hosting configurations.

• Practical familiarity with building and scaling Infrastructure-as-Code delivery templates (AWS CDK and Terraform workflows).

• Background auditing platform compliance configurations against security frameworks (such as SOC2, ISO, or HIPAA parameters).

• Experience operating within global, distributed, or near-shore delivery matrix models where core architectural choices are retained by an onshore owner.

Soft Skills

• High emotional intelligence to navigate complex matrix environments, driving consensus on design choices across engineering leads, corporate product owners, and executive sponsors.

• The ability to uphold rigid enterprise platform standards and strict multi-tenant security boundaries with diplomacy, unblocking teams without compromising design integrity.

• A natural leader who takes pride in elevating and mentoring a growing LATAM engineering team, serving as a highly credible champion of platform engineering best practices.
