What You’ll Do:
- Facilitate architectural collaboration by guiding and supporting teams in evolving application architecture that reflects shared ownership, aligns with business objectives, and ensures scalability, security, and maintainability.
- Collaborate with software engineers, product managers, and technical leaders to translate product requirements into scalable technical solutions.
- Design, advocate for, and support microservice-based architectures, ensuring services are independently deployable, observable, and resilient.
- Define and maintain architectural standards, patterns, and guidelines, including documentation and communication of key decisions.
- Provide hands-on support and mentorship to engineering teams, performing code and design reviews to ensure adherence to architecture principles.
- Lead the selection and integration of appropriate technologies, tools, and platforms for application development.
- Ensure architecture supports regulatory and security requirements (e.g., ISO 27001, PCI-DSS, GDPR).
- Actively participate in system design, capacity planning, and performance optimization efforts.
- Continuously assess and improve architectural practices and frameworks across teams.
- Communicate architectural strategy, trade-offs, and risk factors to stakeholders.
Who You Are:
- A pragmatic technical leader with a deep understanding of designing large-scale, distributed systems.
- A strong communicator who can clearly explain technical concepts to engineers and product managers.
- Ability to influence architectural direction across multiple engineering teams.
- Passionate about clean architecture, system design, and long-term sustainability of software systems.
- Strong sense of ownership and accountability for quality, performance, and security.
- A collaborator who thrives in cross-functional teams and brings others along on the architectural journey.
- Always seeking continuous improvement and not afraid to challenge the status quo in pursuit of better solutions.
- Comfortable making decisions under uncertainty and balancing short-term needs with long-term goals.
What You’ll Need:
- Proven experience designing and developing distributed, cloud-native architecture and deployment models using a microservices architecture.
- Hands-on experience with cloud-native development in public cloud environments such as AWS, Azure, or GCP.
- Strong knowledge of system integration, API design, and modern software design principles.
- Familiarity with performance engineering, security design, and operational excellence.
- Extensive Software Engineering experience with at least 2 years in an Architecture-focused role.
