[Hiring] Senior Platform Engineer @LottieFiles

Role Description

You will be part of the Platform team at LottieFiles, which builds and maintains the core systems that power our products covering authentication, federated GraphQL, data orchestration, and application architecture.

As a Senior Platform Engineer, you will champion developer experience across the organization — building the tooling, workflows, and golden paths that make it easier for every LottieFiles team to design schemas, develop subgraphs, and ship, treating internal developers as customers and platform capabilities as products.

To deliver that experience, you will design, build, and maintain the federated GraphQL gateway (Federation v2), gRPC services, and authentication service that power LottieFiles products, ensuring scalability, security, resilience, and compliance.

You are a systems thinker who instruments, profiles, and optimizes running systems — you care about raw speed and latency, because a faster platform means a better experience for the developers building on it and the users they serve.

You will also mentor peers and contribute to knowledge sharing across the team.

Responsibilities

• Champion developer experience and enablement across the organization by establishing the architecture patterns, runtime tooling, workflows, and documentation around the federated gateway.
• Measure and improve developer experience continuously — gathering feedback from engineering teams, tracking adoption of platform tooling, and removing friction points.
• Design, build, and maintain our federated GraphQL gateway (Federation v2) and gRPC services — ensuring scalability, security, and high availability.
• Develop and maintain the platform's authentication service, including OAuth and SAML single sign-on integrations for enterprise customers.
• Build observability into our GraphQL gateway and platform APIs — metrics, distributed tracing, and structured logging.
• Collaborate with product, engineering, and DevOps teams — and with external vendors — to align platform initiatives with business and technical goals.
• Take ownership of issues and incidents, seeing them through to resolution and improving long-term system reliability.
• Provide guidance and mentorship to peers, sharing knowledge and best practices to elevate team expertise.

Qualifications

• 5+ years of hands-on experience in software development within modern engineering environments, building and operating production services at scale.
• Deep understanding of JavaScript and TypeScript, with strong experience in Node.js and service-to-service APIs such as gRPC.
• Strong experience building developer tooling and improving developer experience across an engineering organization.
• Deep, hands-on experience building and operating federated GraphQL gateways using Federation v2.
• Strong experience building observability into GraphQL and other APIs.
• Good understanding of authentication systems and protocols such as OAuth 2.0, OIDC, and SAML.
• Strong experience designing and operating cloud-based distributed systems (AWS or similar).
• Strong communication and collaboration skills.
• Experience with AI-native systems is a plus.

Requirements

• Experience with React or similar frontend frameworks, or with a systems programming language is a plus.
• Experience in compliance-driven environments such as SOC 2 is a plus.
• Kubernetes experience is a plus.
