Senior Full Stack Engineer

Senior Full Stack Engineer
– Build, Scale, and Shape the Future of Predictive AI –

At Neurons, we’re revolutionizing how brands understand and engage with people. By combining state-of-the-art AI with deep neuroscience insights, we enable companies to predict consumer responses in seconds; transforming marketing into something truly predictive and actionable.

We’re looking for a Senior Full Stack Engineer to help us push this mission forward. This isn’t a role about ticking boxes; it’s about building systems that scale, shipping products that deliver impact, and raising the engineering bar as we grow. Come join our Product and Engineering team, and be a part of a vibrant growing team that prides itself on delivering high quality products that are heavily valued by our customers.

If you’re passionate about designing great technology and seeing it make a difference in the real world, you’ll thrive here.

How We Work

At Neurons, we believe success comes from empowered engineers solving customer problems directly. We continuously optimize our team structure and processes to support this mindset.

Our SDLC evolves constantly. Rather than sticking to a rigid framework, we adopt what works for the current situation and discard what doesn't. We follow the core tenets of Shape Up, giving engineers the context and focus to achieve ambitious goals in 6-week cycles.

For each cycle, small teams (2–3 engineers) form to tackle specific features or problems.
Each cycle is followed by a 2–3 week cooldown focused on technical debt, bugs, and platform enhancements, ensuring a healthy balance between new features and stability.

What You'll Be Driving

Design & Scale the Core Platform
You’ll architect and build our backend services that power our predictive insights, ensuring they are fast, secure, and highly scalable. Your work will enable our platform to process increasing data volumes and deliver real-time results as we grow.

• What helps you succeed: Deep experience with Python (ideally Django or FastAPI), designing distributed systems, and implementing asynchronous processing or microservices.

Deliver Features That Matter - Fast
You’ll work closely with product and design to translate ambitious ideas into working software, building everything from backend logic to frontend interfaces. Your ability to deliver end-to-end functionality will allow us to release new capabilities quickly and confidently.

• What helps you succeed: Strong skills in TypeScript and React, plus experience delivering full-stack features from concept to deployment.

Ensure Reliability, Quality, and Clean Code
You’ll drive engineering excellence through clean, maintainable code, robust testing practices, and thoughtful architecture. Every release you ship should strengthen the platform and make it easier to evolve over time.

• What helps you succeed: A track record of building reliable systems with strong testing strategies (unit, integration, end-to-end), and familiarity with principles like SOLID, TDD, or BDD.

Shape Product Direction With Your Expertise
As a senior engineer, you’ll collaborate closely with cross-functional teams to shape technical decisions and influence the product roadmap. You’ll balance ideal architecture with practical business needs, always aiming to deliver maximum impact.

• What helps you succeed: Experience in product planning, breaking down holistic problems into concrete steps and explaining how each step supports solving the broader problem, making architectural decisions (ADRs/RFCs), and aligning technical work with business goals.

Mentor & Multiply Your Impact
You’ll help build a strong, collaborative engineering culture, mentoring junior developers, leading by example in code reviews, and sharing best practices.

• What helps you succeed: Comfort leading technical discussions, guiding peers, and raising the bar for engineering quality.

What Success Looks Like

• Our products and data pipelines scale smoothly to meet growing demand.

• You help deliver real value to our customers, whether through exciting new features or meaningful improvements to existing functionality.

• Codebases become cleaner, more maintainable, and easier to extend.

• Engineering choices directly shape and accelerate the product roadmap.

• Your technical leadership makes the entire team stronger and more effective.
