Company mission
To encrypt the web; the goal is zero data breaches, and the end-state is everything encrypted everywhere.
Role
Who you are
- We’re looking for people with a strong background or interest in building distributed, high-throughput systems and networks in the payments ecosystem
- Deeply technical. You have strong fundamentals in distributed systems, networking, and high-throughput infrastructure — not just frameworks
- You think about problems like global state replication, data consistency, and performance engineering
- You care about how things work under the hood and you're comfortable going deep
- Relentlessly product-minded. You think about the developer experience of every API you design
- You care about what gets shipped, not just what gets built
- You want to build tooling and APIs that developers actually love
- You measure your work by impact, not output
- Founder energy. You may have started something before, or you want to one day. Either way, you operate with ownership, urgency, and bias for action
- You take pride in working on projects to successful completion — and you don't wait to be told what to do
- An excellent communicator. You write clearly
- You can explain complex technical decisions to non-technical people
- You're comfortable in front of customers and deeply involved in the product development lifecycle
- Excellent taste. In code, in APIs, in visual design, in documentation
- You know what good looks like and you hold yourself and others to a high bar
- Full-stack, not pigeonholed. You're comfortable across the stack — backend, frontend, infrastructure — and you enjoy working with many languages, frameworks, and programming paradigms
- You'd rather learn something new than stay in your lane
- Curious. You want to understand how card networks actually work. You dig into RFCs. You read source code for fun. You ask why
- A good human. Kind, generous, low ego
- You thrive in a collaborative environment with people from different backgrounds
- The kind of person who makes a team better just by being in the room
What the job involves
- We're hiring Product Engineers to join our Cards team in London
- This isn't a "build to spec" role. You'll own problems end-to-end — from talking to customers, to designing the API surface, to shipping production code, to measuring whether it worked
- You'll be building core payments infrastructure: tokenization, network integrations, and whatever comes next
- We work mostly in Rust and Node.js, built on AWS. But we care far more about your engineering skill than knowledge of a particular language or framework
- Designing and building developer-facing APIs and primitives for data security
- Encrypting and decrypting data at tens of thousands of requests per second
- Multi-PSP payments orchestration — routing card transactions across processors to optimise cost and acceptance rates
- Working with low-level networking primitives to create high-throughput forward and reverse proxies
- Leveraging Confidential Computing and secure enclaves to build the most secure systems in the cloud
- Developing custom serverless runtimes for Python and Node.js
- Shipping full-stack: backend services, APIs, SDKs, UI components, and documentation
- Working directly with customers — understanding their payment stacks, debugging integrations, and shaping the roadmap from real problems

Our take
Data privacy can be complicated for those who don’t want to read thousands of pages of regulations. Evervault is focused on building a unique data-privacy interface that developers can use when creating software, providing simple developer tools to deploy applications in hardware-hardened containers, enabling clients to focus on building products rather than security.
Evervault plans to offer its service as an API to allow developers to seamlessly build it into the software stack of whatever they are creating. Around 3,000 developers are on the company's waitlist for its encryption engine, such as drone delivery firm Manna, fintech startup Okra and health tech company Vital.
The company has gained a lot of traction in recent years, processing more than $5 billion in transactions. It's using a substantial 2026 fundraise to grow its engineering and product teams, expand its encryption infrastructure and boost its R&D efforts.
