About the Role

SONIFI Solutions, Inc. is seeking a Staff Software Engineer of API Platform to play a critical role in modernizing and transforming our API ecosystem. This position will lead the design and implementation of a scalable, secure, and high-performance orchestration layer that powers first- and third-party integrations, data transformations, monitoring, and BI.

In this role, you will bring deep expertise in distributed backend systems, API governance, and data unification across complex product ecosystems. You will provide technical leadership and guidance across engineering teams, establishing standards, ensuring reliability, and accelerating innovation through a cohesive platform foundation.

Why This Role Matters

The Platform API will serve as the central nervous system of SONIFI's technology environment-enabling innovation, accelerating product delivery, and opening new business opportunities through integrations and data insights. This role offers the autonomy to define how SONIFI connects its products, partners, and future experiences.

What You'll Do

Collaborate with Enterprise Architecture to define and drive the technical architecture and roadmap for the Platform API and related infrastructure, establishing standards for authentication, data access, and versioning across all product domains.

Design and implement core API services that unify multiple product backends into a single, consistent developer experience.

Partner with engineering SMEs and Architects to support migration of existing systems into the new platform, ensuring a smooth transition with minimal operational disruption.

Promote API-first design principles across product teams and establish guidelines for REST/GraphQL patterns, schema evolution, and API documentation.

Work cross-functionally with product, data, and frontend teams to identify and implement common services and abstractions that reduce duplication and accelerate innovation.

Implement API observability and governance to ensure scalability, reliability, and performance for internal and external developers.

Partner with Security and Compliance to enable external API exposure, including OAuth2, rate limiting, tenant isolation, and audit trails.

Mentor and influence senior and mid-level engineers, promoting best practices in distributed systems design, service ownership, and platform reliability.

Represent engineering in strategic technical discussions, balancing long-term vision with near-term business needs and partner integrations.

What You'll Need

8+ years of professional software engineering experience, including 2+ years at Staff level or equivalent technical leadership.

Proven experience designing and scaling APIs (REST, GraphQL, or gRPC) supporting multiple products or business lines.

Strong proficiency in modern backend technologies such as Python, Node.js, TypeScript, Go, and cloud-native design on AWS.

Experience with API gateways, service meshes, and authentication frameworks (AWS API Gateway, Envoy, OAuth2, OpenID Connect).

Deep understanding of data modeling and system integration, including event-driven or microservice architectures.

Familiarity with observability stacks (Grafana, Prometheus) and CI/CD automation.

Excellent communication skills with a demonstrated ability to drive technical alignment across multiple teams.

Bonus: Experience with developer platforms, public API ecosystems, partner integrations, SDKs, webhooks, or sandbox environments.

Together, we can build your future! SONIFI pays a competitive salary for this role based on a variety of factors including location, experience, education, specialty, and training. This position is also eligible for PTO, holidays, health, dental, vision, retirement plan, pet insurance, on-demand pay, and a variety of other benefits.
