About the Role
We are looking for an Application Architect to join our engineering organization and help shape the future of our SaaS platform. Our platform powers retail media solutions for global retailers and CPGs, enabling end-to-end advertisement campaigns across e-commerce sites, in-store channels, and social media platforms.
This role is pivotal in defining architectural guardrails, frameworks, and patterns that enable multiple squads to deliver scalable, reliable, and secure solutions. You will combine hands-on technical depth with the ability to influence and align engineering managers, lead engineers, and product leaders. This is not an ivory-tower role — you will actively partner with teams, ensuring architecture decisions are practical, business-aligned, and execution-ready.
What You’ll Do
- Architectural Leadership: Define and evolve application architecture in line with business and product strategy for a global retail media SaaS platform.
- Set Guardrails: Establish repeatable patterns for microservices, APIs, identity/auth, observability, and data flows.
- NFR Ownership: Ensure non-functional requirements (scalability, reliability, resiliency, observability, security, maintainability) are embedded into design decisions.
- Cross-Squad Influence: Collaborate with multiple squads (frontend, backend, BFF, platform services) to align on architectural choices.
- Tech Evaluations: Lead structured assessments of new tools and frameworks (e.g., OPA, SpiceDB, caching, API gateways) and guide adoption.
- Decision Frameworks: Move teams away from ad-hoc debates by creating clear frameworks for architectural decision-making.
- Mentorship: Partner with engineering managers and lead engineers to strengthen design-level thinking and technical maturity.
What We’re Looking For
- Hands-on technical expertise in:
- .NET Core, C#, REST APIs, microservices.
- If are open for candidates with Java expertise
- Event-driven architectures (Pub/Sub, Kafka, or similar).
- Databases (Postgres, SQL Server, caching strategies with Redis or Couchbase).
- Identity & authorization frameworks (Auth0, OPA, SpiceDB, OpenFGA).
- Observability platforms (New Relic, Prometheus, Grafana).
- Cloud-native experience (GCP preferred; AWS/Azure acceptable).
- Proven ability to architect SaaS or large-scale product platforms with multi-squad or multi-tenant complexity.
- Strong track record of embedding NFRs into platform and product design.
- Excellent communicator — can simplify trade-offs for both engineers and business stakeholders.
- Experience influencing without authority and driving closure across multiple teams.
What Will Make You Stand Out
- Experience designing multi-tenant SaaS platforms in the adtech or retail media domain.
- Exposure to API gateway solutions (Apigee, Kong, Ocelot).
- Knowledge of micro-frontend architectures or Backend-for-Frontend (BFF) patterns.
- Passion for balancing innovation with pragmatism.
- A track record of mentoring engineers on design and architecture.
Why Join Us?
- Build and scale a retail media SaaS platform at the heart of the global adtech ecosystem.
- Work on high-impact problems at the intersection of retail, data, and advertising technology.
- Influence the architecture of systems powering leading retailers and global brands.
- Be part of a culture that values engineering excellence, collaboration, curiosity, and growth.
Apply now to help shape the backbone of our retail media SaaS platform and make an impact at scale.
