This is a strategic, hands-on leadership role responsible for architecting scalable, secure, and high-performing solutions that power eCapital’s suite of digital financial services.
The ideal candidate will combine deep technical expertise with strong leadership skills—capable of guiding engineering teams, influencing technology strategy, and ensuring the long-term health and evolution of our software platforms. You will be instrumental in building cloud-native systems, modernizing legacy components, and ensuring that architecture decisions enable business agility and innovation at scale.

Key Responsibilities:
Architecture & Strategy

  • Lead the design of scalable, cloud-native solutions that support both enterprise and consumer applications.
  • Evaluate emerging technologies, frameworks, and patterns to ensure eCapital remains at the forefront of innovation.
  • Champion architectural principles such as modularity, reusability, observability, and resilience.
Solution Design & Delivery
  • Provide technical leadership throughout the software development lifecycle—from concept through deployment and maintenance.
  • Guide teams in designing APIs, microservices, and integration patterns for high-performance, distributed systems.
  • Oversee front-end and back-end architectural consistency across applications using modern frameworks (.NET Core, React, Angular, etc.).
  • Drive adoption of DevOps practices, CI/CD pipelines, and infrastructure-as-code for efficient and reliable delivery.
Governance & Collaboration
  • Partner with product, data, and infrastructure teams to ensure architectural alignment across domains.
  • Establish coding and design standards that promote quality, scalability, and maintainability.
  • Provide mentorship and technical guidance to developers and engineering leads across multiple teams.
  • Participate in architectural reviews, technical design discussions, and strategic planning initiatives.
Performance & Optimization
  • Proactively identify system bottlenecks, reliability issues, and performance gaps, and drive effective solutions.
  • Implement robust monitoring, logging, and alerting strategies to support system health and operational excellence.
  • Ensure security, compliance, and data protection are embedded throughout system design and development.
Qualifications:
Technical Expertise
  • 10+ years of professional experience in software development and architecture, with proven experience designing cloud-native enterprise solutions.
  • Deep understanding of modern frameworks and technologies across the stack (e.g., .NET Core, React, Angular, Node.js, SQL/NoSQL databases).
  • Expertise in system design, distributed architecture, and API development.
  • Strong experience with DevOps tools, CI/CD, and cloud platforms (AWS, Azure, or GCP).
  • Experience in financial services, SaaS, or other high-transaction-volume environments is an asset.
Leadership & Communication
  • Demonstrated success providing technical leadership across multiple projects or product lines.
  • Ability to translate complex technical concepts into clear, actionable business language.
  • Strong collaboration and mentorship skills with the ability to influence without direct authority.
  • Excellent problem-solving, communication, and organizational abilities.
We Bring:
  • Competitive Compensation
