Backend Engineer

Upside is a software consultancy built by engineers, for engineers. We partner with global companies to solve real, complex technical challenges. We’re deep into Applied AI and R&D, building both production-grade platforms for clients and our own open-source tools like Enthusiast (Agentic AI framework).

We operate in a Forward-Deployed model. We don’t sit behind a wall of specs or wait for the tickets. We get into the trenches with the client, identify the actual challenges, and take full ownership of the solution. Our teams are small (3–9 people), autonomous, and cross-functional.

What it means for you

You won’t be assigned to a random project. You’ll partner directly with founders and CTOs on technical decisions, shaping systems - not just implementing them. You’ll  have the autonomy to choose  the right tools and the ownership to ensure the architecture performs under pressure.Your focus stays where it counts: mission-critical logic and high-impact experiments, not repetitive tasks and countless meetings.

We don't do "safe or predictable". You’ll contribute to strategic open-source projects and build  AI-driven solutions.

Role Overview 

As a Backend Engineer, you’ll be integral to building and scaling platforms for our global clients. You’ll join a high-performing team where your voice matters. You’ll design and implement resilient systems while staying close to the code, bringing solutions to the table instead of just reporting problems.

Responsibilities

• Technical Execution: Build and maintain scalable backend systems with a focus on clean, maintainable code.

• Proactive Problem Solving: Identify issues early and propose actionable ways to fix or optimize them.

• Collaboration: Work closely with the team and stakeholders to translate requirements into working technology.

• Knowledge Sharing: Share your findings and lessons learned from the code to help the team grow.

• AI Implementation: Support the integration of Applied AI features into client products.
