Job Description

As Swissquote continues to expand its digital assets custody activities, we are looking for a Senior Software Engineer to join our Software Engineering Infrastructure Department.

You will be part of the team developing and maintaining our custody, staking, and liquidity management solutions — core components of Swissquote’s digital asset ecosystem.
Beyond pure development, you will play a key coordination role, ensuring smooth alignment between engineers, internal stakeholders (Compliance, ALM, Risk, IT-Sec, Business), and external partners.

Your technical expertise and communication skills will help bridge business requirements, regulatory constraints, and engineering realities to deliver secure, compliant, and efficient solutions.

Your Responsibilities

  • Participate actively in the design, development, and delivery of backend services for custody, wallets, staking, and liquidity management (mainly in Java / Spring Boot).
  • Act as a coordination point within the team: clarify requirements, track progress, and ensure consistency between product, engineering, and external vendors.
  • Translate evolving business and regulatory needs into clear and actionable technical tasks.
  • Collaborate closely with Compliance, Risk, and ALM to anticipate regulatory impacts on existing systems and propose pragmatic technical solutions.
  • Maintain alignment with external partners (custodians, staking providers, blockchain analytics vendors) to ensure successful integrations and smooth operations.
  • Support project planning and delivery follow-up in collaboration with the Program Manager and Product Owners.
  • Contribute to continuous improvement of internal tools, documentation, and delivery processes.
  • Maintain a strong focus on quality, security, and operational reliability of the custody systems.

Qualifications

  • 5+ years of experience in backend software engineering, ideally within a banking, fintech, or digital assets environment.
  • Strong command of Java (Spring Boot), REST APIs, and SQL.
  • Solid understanding of software lifecycle management and collaborative delivery in multi-stakeholder environments.
  • Proven ability to coordinate between teams, manage evolving requirements, and maintain alignment in dynamic or regulated contexts.
  • Excellent communication and analytical skills — able to challenge and clarify complex functional or regulatory topics.
  • Interest or experience in digital assets, blockchain technologies, or staking infrastructure.
  • Fluent in English (French is an asset).

Additional Information

Why Join Us

You’ll contribute directly to the foundation of Swissquote’s digital asset infrastructure, working at the crossroads of technology, regulation, and innovation.
This role is ideal for a seasoned engineer who enjoys technical work but thrives in environments where coordination, adaptability, and clarity are just as essential as code quality.

What does a React developer in web3 do?

A React developer in the context of web3 is a developer who is using the React JavaScript library to build user interfaces for decentralized applications (dApps) that run on the Ethereum blockchain

These dApps often use smart contracts to facilitate transactions and other interactions on the Ethereum network

Overall, the role of a React developer in web3 involves using your skills in React development to help build cutting-edge decentralized applications that leverage the power of the Ethereum blockchain

As a React developer in web3, some of your responsibilities might include:

  • Integrating the dApp with the Ethereum blockchain. This might involve using tools like web3.js and Ethers.js to connect to the Ethereum network and interact with smart contracts.
  • Building the user interface for a dApp using React. This could involve creating components for the various elements of the dApp, such as buttons, forms, and other input elements.
  • Implementing features that are specific to decentralized applications, such as handling cryptocurrency transactions and displaying data from the blockchain in a user-friendly way.
  • Collaborating with other members of the development team, such as blockchain engineers and designers, to ensure that the dApp functions properly and meets the needs of the end users.
