Senior Platform Engineer

Saga is building a suite of products across the crypto ecosystem — from consumer fintech apps to DeFi protocols and the SagaEVM chain. Our mission is to build products and infrastructure that push the crypto ecosystem forward — whether that's consumer applications, DeFi primitives, or the chains themselves.

Our team is world-class — veteran web3 entrepreneurs and builders from Ignite (Tendermint), Apple, Twitter, NVIDIA, and Skuchain — and we're looking to grow as we scale Mino to millions of users.

We offer a flexible, remote working environment. You can expect a warm welcome from a friendly and international team that will support you in your personal and professional growth. This is an exciting opportunity to take an active part in the blockchain space and contribute to the decentralization of the future.

The Role

As a Senior Platform Engineer, you'll own the backend systems and infrastructure that power our products. You'll build the services, APIs, deployment pipelines, and platform tooling that enable a fast-moving product team to ship reliable, performant features to end users. This role sits at the intersection of backend development and infrastructure — you'll write application-level code and also make sure it runs smoothly at scale.

The Work

• Design, build, and maintain backend services and APIs that power core product features (transactions, wallet management, DeFi integrations, user accounts)
• Own and evolve the infrastructure layer — CI/CD pipelines, container orchestration, deployment automation, and infrastructure-as-code
• Build and operate scalable, reliable systems on cloud infrastructure (AWS, GCP, or similar)
• Develop high-quality, performant, modern, clean and readable code within tight deadlines
• Develop internal tooling and platform primitives that accelerate the product engineering team
• Implement observability, monitoring, and alerting to ensure high availability and fast incident response
• Collaborate closely with product, design, and frontend engineers to deliver end-to-end features
• Contribute to architecture decisions, technical documentation, and engineering standards as the team grows
• Own the development and maintenance of the project from ideation to deployment

Must Have

• 7+ years of experience in backend engineering, with meaningful exposure to infrastructure, platform, or DevOps/SRE work
• Strong proficiency in Golang (5+ years)
• Experience designing and building production APIs and microservices at scale
• Hands-on experience with Kubernetes, container orchestration, and cloud infrastructure (AWS, GCP, or similar)
• Familiarity with infrastructure-as-code tools (Terraform, Pulumi, or equivalent)
• Experience building and maintaining CI/CD pipelines for multi-service deployments
• Strong understanding of distributed systems, databases, and systems-level debugging
• Exceptional problem-solving, analytical, and communication skills

Nice to Have

• Experience with blockchain systems or integrating blockchain-based backends into consumer-facing products
• Understanding of cryptographic primitives (public/private keys, hash functions, Merkle trees)
• Experience with the Cosmos SDK / CometBFT technology stack
• Background in fintech, payments, or wallet infrastructure
• Experience with performance optimization, load testing, and capacity planning
• Familiarity with observability stacks (Prometheus, Grafana, Datadog, or similar)
• Contributions to open-source projects

Benefits

• Work remotely from anywhere in the world
• Work on exciting things at the intersection of fintech and crypto
• Flexible working hours
• Flexible vacation policy
• Competitive salary
• Stock options
• Full benefits*

*Medical, Dental, Vision, and 401k retirement plans for US employees only.
