About this role
Do you want to build the integration layer between traditional banking and the emerging world of digital assets and be part of the core Digital Assets team of SEB?
Make job search work for you
Turn a broad, stressful search into a focused weekly routine.
Join SEB’s Digital Assets team and be part of an exciting new chapter in the evolution of financial services! You’ll work alongside experienced colleagues across technology, payments and business to help shape SEB’s approach to digital assets.
About this role:
As a Solution Developer, you will help build an orchestration layer connecting SEB’s core banking systems with external custody and wallet providers and a token issuer, starting with Ethereum.
SEB is a founding member of Qivalis, a consortium of leading European banks working to launch a regulated, euro-denominated stablecoin. The platform will connect existing banking and payment infrastructure with digital-asset services, supporting this initiative and future use cases.
You will design, develop and maintain secure, resilient backend services and API integrations using .NET, Python and Terraform, working with REST APIs, webhooks, mutual TLS and OAuth 2.0. You will help ensure reliable transaction processing, monitoring and compliance with relevant security and regulatory requirements.
Working closely with product management, payment specialists, architects, security and compliance teams, as well as external technology providers, you will translate business and regulatory needs into robust technical solutions.
In this role, you will:
Design and develop an orchestration layer between core banking, custody and wallet providers, and token issuers
Build and maintain containerised back-end services using .NET and Python, with infrastructure defined through Terraform
Design secure API integrations using REST, webhooks, mutual TLS and OAuth 2.0
Integrate banking and payment flows with custody platforms, digital wallets and blockchain-based services
Design transaction flows for Ethereum and ERC-20 tokens, including gas management, transaction finality and operational exception handling
Establish secure approaches to cryptographic key management using technologies and standards such as HSM, MPC, PKCS#11 and hierarchical key derivation
Support payment integration based on SEPA Instant and ISO 20022, including pacs.008 messages
Embed AML and KYC screening, Travel Rule controls and on-chain analytics into relevant transaction flows
Build secure, observable and resilient services on Kubernetes and Google Cloud, including multi-zone disaster recovery
Apply engineering practices in line with MiCAR, DORA and SEB’s security and operational requirements
To thrive in this role, we believe you have:
Strong hands-on experience developing backend services using .NET.
Experience building API integrations and containerised services, with practical knowledge of Python and Terraform.
Experience with REST APIs, webhooks and secure authentication mechanisms such as mutual TLS and OAuth 2.0.
Experience with payments, banking integrations or other business-critical transaction platforms where security, traceability and resilience are essential.
The ability to translate business and technical requirements into robust solutions and collaborate effectively across technology, product, security and compliance teams.
It’s a plus if you have experience with:
Blockchain and digital assets: Ethereum transactions, ERC-20 tokens, gas management, transaction finality or Solidity.
Cryptographic security and key management: HSM, MPC, PKCS#11 or key derivation standards such as SLIP-0010 and BIP32.
Payments and financial messaging: SEPA Instant and ISO 20022, particularly pacs.008.
Custody platforms: Fireblocks, Ripple, Taurus, Zodia or similar.
Compliance and regulation: AML/KYC screening, the Travel Rule, on-chain analytics tools such as Chainalysis, Elliptic or TRM Labs, and awareness of MiCAR and DORA.
Cloud infrastructure and resilience: Kubernetes, Google Cloud and multi-zone disaster recovery.
We value clear communication, a pragmatic approach to problem-solving and the ability to work in a domain where technology, standards and regulatory expectations continue to evolve.
You have a genuine interest in digital assets and AI, take ownership of your professional development and use AI tools thoughtfully to improve your development workflow and productivity.
What we offer:
We offer many experiences and benefits to our employees, and there is nuance to every individual’s career experience, but the elements that define the core of our offering are:
The opportunity to contribute to the development of SEB’s digital-assets platform and its first blockchain-based product
Professional development in an emerging technology area with direct relevance to the future of financial services
Insight into stable coins, digital wallets, blockchain integration and institutional financial markets
A dynamic, professional and multicultural environment
An empowering and inclusive workplace culture
A hybrid workplace setup
