Job Description

Some engineers write great code.

Others quietly shape systems, guide decisions, and influence the way entire teams build.

We're hiring a Senior Software Engineer to do just that.

Build Systems Worth Trusting | Global Saas Company | Remote & Hybrid Options

Up to $175K + Super + Equity

You’ll join a product-led, values-first organisation where engineering is trusted not micromanaged and where scale, quality, and simplicity aren’t just buzzwords, they’re a collective obsession.

You’ll bring technical depth, but also clarity. You’ll mentor with empathy, challenge with kindness, and solve problems that aren’t always clean or easy. But they’re real. And they matter to millions of businesses and the people behind them.

What your days might look like:

• Designing and evolving scalable services that support thousands of requests per second

• Championing performance, security, and resilience across distributed systems

• Partnering with product and design to shape features from inception to delivery

• Supporting and guiding other engineers through code reviews, pairing, and structured growth

• Influencing architectural decisions, technical strategy, and engineering standards

Our core tech:

• Backend: .NET 6+, C#, RESTful services

• Frontend: React, Typescript

• Cloud: AWS (SQS, ECS, Lambda, API Gateway, CloudWatch)

• Data: SQL Server, Redshift, and evolving cloud-native data services

• Tooling: CI/CD, IaC (CloudFormation), feature flags, observability platforms

What makes this place different:

• Your voice counts, engineers shape the why, not just the how

• There’s genuine care for wellbeing inside and outside the codebase

• Impact is felt your work touches millions, not just internal stakeholders

Benefits that actually mean something:

• Employee share scheme (real ownership in the business)

• 26 weeks paid parental leave

• Wellbeing days + additional annual leave 

• Dedicated L&D budget, career pathways, and internal mobility

• Flexible hybrid and remote working, with supportive leadership

• A carbon-neutral workplace with deep commitments to sustainability and DEI

If you’ve been looking for a team that matches your ambition with humility and wants you to lead by example, not title - this could be your place.
