Job description
🌍 Our Vision & Mission
At Payflows, we give finance teams the tools to reclaim their time and energy. Our platform weaves together banking connectivity, payments, AI, and procurement so they can ditch the busywork and focus on what really moves the needle.
🤝 Why Join Us?
We’re a small, mighty team who’ve earned our stripes at Airbnb, Luko, BNP Paribas, and Facebook. It’s not always easy—things move fast, and we expect a lot—but if you’re hungry for impact, you’ll find it here.
🛠️ We’re builders at heart. We move fast, think deeply, ship often — and we’re always hungry to learn more. You'll collaborate closely with product and tech to craft elegant backend systems that scale as fast as we do.

🚀 What You’ll Do
You'll own the infrastructure for a product that real finance teams rely on every day.
For us, infrastructure is not just about uptime; it's about reliability, security, and trust - especially when money and automation are involved. The platform has to be boring in the best possible way: predictable, observable, and safe to deploy to.
In a typical week, you might:
Evolve our infrastructure-as-code to add a service, a queue, or a whole new environment.
Improve our CI/CD pipelines so engineers ship safely and fast, dozens of times a day.
Investigate a production issue: a latency spike, a failing deploy, a database under load.
Strengthen observability with dashboards, alerts, and traces, so we catch problems before customers do.
Harden our security, secrets management, and access controls.
Tune cost and performance across our AWS footprint.
Your time will be split between building new platform capabilities and making what already exists more reliable . Both matter.
You'll help shape the foundation that everything else stands on: the pipelines, environments, and guardrails that let engineers and our AI agents act safely in production.
You'll work closely with backend, frontend, and the AI team. We expect you to take ownership of the platform and make it more reliable over time, not wait for tickets.
💻 Our current tech reality
Our stack evolves based on our challenges, but we care more about good design than trendy tools
We're an AWS shop, and we lean on managed services and infrastructure-as-code so the system is reproducible and easy to reason with. A growing part of our world is making the backend a set of reliable, deterministic tools that AI agents can call, which raises the bar on reliability even further.
Cloud: AWS
Infra-as-code: Pulumi (Python)
Compute: ECS + Lambda, serverless when it makes sense
Data: PostgreSQL on RDS/Aurora
CI/CD: GitLab CI
Orchestration: Airflow (MWAA)
Observability: Grafana Cloud, CloudWatch, Sentry
Auth & identity: Cognito, IAM
Edge & frontend: API Gateway, ALB, AWS Amplify for the web app
Some of this is clean, version-controlled, and reproducible. Other parts grew fast and live a little too much in people’s heads instead of in code. Closing that gap is a big part of why this role exists.
Over the next year, we'll focus on:
Making every environment reproducible from code
Better observability and alerting, fewer surprises
Tightening the security and compliance posture that comes with handling enterprise finance data
Faster, safer deploys
Keeping AWS costs sane as we scale
🧑💻 What we’re looking for
5+ years of experience with Python or any other OOP language
Backend expertise : APIs, microservices, architecture best practices
Databases & SQL : Data modeling, query optimization
Git lover : Comfortable with version control and code reviews
Pragmatic engineering mindset : Build, test, refine, simplify—smart shortcuts when time is tight
🧩 Bonus points if you’ve worked on:
B2B SaaS or finance/ERP tools
BaaS APIs or payment infra
Serverless, AWS, event-driven architecture exposure
✨ Who's going to thrive with us
You'll probably feel comfortable here if:
You think in systems and instinctively automate yourself out of repetitive work.
You treat infrastructure as code, not as pets.
You stay calm during incidents and are genuinely good at root-causing.
You care about security, because you're handling other people's money.
You are autonomous and take ownership of what you ship.
You take initiative and lead by example.
You're pragmatic about trade-offs.
You communicate with kindness and clarity.
You don't need to know everything about AI - but you must be curious about it and excited to build the reliable foundation that agents run on 🤖
🧩 What you'll get from this role
Real ownership over the platform the whole company runs on.
Direct impact on reliability, security, and how fast every engineer can ship.
A mix of platform building, system design, and reliability work.
Exposure to real scaling and production challenges.
The chance to help build the foundation of an agent-driven product from the inside.
