Cosmos Sdk Developer information

What are the key skills and qualifications needed to thrive as a Cosmos SDK developer, and why are they important?

To thrive as a Cosmos SDK Developer, you need strong proficiency in Go programming, blockchain architecture, and experience with the Cosmos SDK framework, often supported by a degree in computer science or related fields. Familiarity with tools like Tendermint Core, REST APIs, and version control systems such as Git is essential, and certifications in blockchain technologies can be beneficial. Problem-solving skills, attention to detail, and effective communication enable collaboration and the ability to address complex technical challenges. These skills ensure secure, scalable, and efficient development of decentralized applications on the Cosmos network.

What are some typical challenges Cosmos SDK developers face when integrating custom modules into a blockchain application?

Cosmos SDK Developers often encounter challenges such as ensuring module compatibility with existing components, maintaining security while extending chain functionality, and handling inter-module communication. Debugging and testing new modules can be complex, especially when managing state changes and message passing. Effective collaboration with other developers and clear documentation are crucial to successfully integrating custom modules without introducing vulnerabilities or performance issues.

What is a Cosmos SDK developer?

A Cosmos SDK Developer is a software engineer who specializes in building blockchain applications using the Cosmos SDK, a framework that allows developers to create custom, interoperable blockchains. These developers work on creating decentralized applications (dApps), modules, and blockchain networks that can easily connect and communicate with other blockchains in the Cosmos ecosystem. They often use programming languages like Go and are familiar with blockchain concepts such as consensus algorithms, governance, and token economics. Their role is crucial in expanding the Cosmos network and ensuring secure, scalable, and efficient blockchain solutions.

Job description

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.
