About The Technical Architect Role

We are seeking a highly skilled Technical Architect who brings real-world architecture experience and excels at working collaboratively with engineers, designers, and stakeholders. This role requires deep technical understanding across our stack—spanning apps, SDKs, SaaS platforms, and distributed systems—and the ability to translate that knowledge into scalable, maintainable, and high-performing architectures that align with our design principles and long-term vision.

The Technical Architect will act as a bridge between technical strategy and implementation, driving architectural consistency across teams while remaining hands-on in guiding system design, documentation, and evolution. You will help define the backbone of our technology by analyzing, documenting, and improving complex systems—applying open standards such as C4 and maintaining clear records of Important Technical Decisions (ITDs) to ensure traceability and shared understanding across the organization.

You will collaborate closely with engineers, product managers, and leadership to design robust and future-proof systems, foster architectural best practices, and mentor teams in achieving technical excellence. From leading design proposals and PoCs to defining reference implementations and modernization paths, you’ll play a key role in ensuring that every part of our technology scales with our ambitions.

Responsibilities

• Design robust and scalable architectures for various systems (apps, SDKs, SaaS platforms, etc.) tailored for our specific tech stack.
• Utilize systems-level thinking to structure components for reliability, scalability, and maintainability.
• Work closely with developers, product managers, designers, and other stakeholders to translate requirements into clear, practical, and forward-looking architectures.
• Write and review technical proposals to ensure alignment with agreed architecture, principles, and long-term technical direction.
• Contribute to guiding development through code reviews, building PoCs, defining skeleton structures, and ensuring technical consistency across teams.
• Promote architectural standards and best practices across the organization to foster consistency, interoperability, and sustainable development.
• Analyze and document existing architectures by deeply understanding current product and system implementations. Use open standards such as the C4 model to visualize and communicate system design.
• Detect and explain core algorithms and design patterns forming the backbone of key systems, summarizing their intent and implementation clearly for diverse audiences.
• Identify and record Important Technical Decisions (ITDs), ensuring they are properly captured, reviewed, and traceable to their rationale and impact.
• Evaluate and evolve existing architectures to improve scalability, maintainability, and performance, proposing pragmatic refactorings and modernization initiatives when needed.
• Mentor and enable engineering teams in system design, architectural principles, and documentation best practices, building a shared culture of technical excellence.
• Keep up to date with new tools, frameworks, and ideas, proactively identifying opportunities to improve our systems, processes, and developer experience.

Qualifications

• 10+ years of experience in software development.
• 3+ years of experience in a Technical Architect, Chief Architect, or similar technical leadership role.
• Strong hands-on experience with JavaScript/TypeScript and/or C++.
• Proven ability to perform and make decisions in fast-paced, dynamic, and evolving environments, balancing agility with long-term architectural integrity.
• Demonstrated ability to analyze, refactor, and document complex systems—transforming them into modular, maintainable architectures using open standards such as C4 and ADRs.
• Deep understanding of architecture principles, design patterns, and modern system paradigms (microservices, event-driven architectures, domain-driven design, etc.), combined with the ability to quickly absorb and adapt to new stacks and tools.
• Proven ability to identify and articulate key algorithms, flows, and design patterns in existing systems, expressing them clearly to both technical and non-technical audiences.
• Demonstrated experience architecting systems for scale—optimizing for high-volume traffic, large user bases, or data-intensive workloads—while navigating trade-offs between performance, reliability, and cost-efficiency.
• Demonstrated leadership in defining architectural standards, driving technical governance, and mentoring engineering teams in best practices.
• Strong problem-solving and system-level thinking, with an aptitude for simplifying complexity and balancing technical depth with pragmatic trade-offs.
• Hands-on experience with containerization and orchestration, including Docker and Kubernetes, as well as CI/CD automation using GitHub Actions, GitLab CI, or similar tools.
• Practical experience with databases and data modeling, covering SQL (e.g.: PostgreSQL, MySQL or similar) and NoSQL (e.g.: MongoDB, Redis or similar) systems.
• Excellent grasp of DevOps principles—version control (Git), build/release pipelines, monitoring, and observability (Prometheus, Grafana, Datadog, OpenTelemetry).
• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related discipline.
