Software Engineer

Senior/Staff Software Engineer – Platform

Remote - United States | Full-time

💰 $150,000 – $350,000 base + competitive equity

We’re working with a rapidly growing, AI-native technology company building the infrastructure behind the next generation of automated financial workflows.

The company has already powered more than $85B in transactions through its platform and is scaling rapidly. They’re looking for a Senior/Staff Software Engineer to join their Platform team and help build the infrastructure, developer tooling and systems that enable engineers to ship faster, safer and more reliably.

This is a highly hands-on engineering role for someone who enjoys working at the intersection of infrastructure, backend engineering and developer experience.

The Role

You’ll treat infrastructure as a product and work closely with engineering teams to improve developer velocity, reliability and scalability.

You’ll be responsible for:

☁️ Owning and evolving AWS infrastructure using Terraform and/or Pulumi

🛠️ Building internal developer tooling, TypeScript libraries and shared SDKs

🚀 Designing and maintaining CI/CD pipelines, including Buildkite

🔄 Building per-pull-request ephemeral environments to make deployment fast and safe

📊 Improving platform observability, reliability and performance

⚡ Designing systems around SLOs, auto-scaling and incident response

🏗️ Solving complex scaling challenges across databases, compute and distributed infrastructure

🧑 💻 Building backend TypeScript tooling that makes product engineers significantly more productive

Tech Stack

• TypeScript

• Node.js

• AWS

• Terraform / Pulumi

• Buildkite

• Docker

• PostgreSQL / Aurora PostgreSQL

• ECS

What We’re Looking For

• 7+ years of software engineering experience

• Strong platform / infrastructure / backend engineering background

• Experience working at a high-growth technology company or startup

• Deep hands-on AWS experience across compute, networking, storage and security

• Strong Terraform and/or Pulumi experience

• Proven experience building and maintaining CI/CD infrastructure

• Strong TypeScript and Node.js skills

• Comfortable making meaningful changes to backend codebases, not just managing infrastructure

• Experience with reliability engineering, including SLOs, error budgets and incident response

• Strong systems and infrastructure design skills

• Excellent written communication and ability to document complex systems

• A strong product mindset around developer experience and internal tooling

Nice to Have

• Buildkite experience

• Experience building ephemeral / per-PR environments

• Production observability experience with Datadog, CloudWatch, Sentry or distributed tracing

• Experience scaling high-throughput systems

• Active GitHub / open-source contributions

• Experience at high-growth companies such as Stripe, Datadog, Cloudflare, Confluent, HashiCorp, OpenAI, Anthropic or similar environments

Why Join?

🚀 AI-native company – building modern technology from the ground up rather than layering AI onto legacy systems

💻 Platform at the centre – your work directly impacts the productivity of the entire engineering organisation

📈 Significant growth – join during a major period of engineering expansion

🧠 Challenging technical problems – work on infrastructure operating at meaningful scale

🌎 Fully remote – work remotely across the US

💰 $150K–$350K base + competitive equity

🏥 Comprehensive benefits including medical, dental, vision, 401(k), HSA/FSA and flexible time off

If you're a Senior or Staff Engineer who loves building infrastructure but still wants to write code, build developer tooling and solve difficult backend problems, this could be a great opportunity to make a significant impact.
