Role Description

As a Full-Stack Software Engineer at Northslope, you’ll be responsible for architecting, building, and scaling high-impact applications across the entire stack—front-end, back-end, and everything in between. Working closely with internal teams and stakeholders, you’ll deliver products that turn complex datasets into mission-critical workflows, tools, and insights.

You’ll spend your time designing user-centric UIs, building robust APIs, and operationalizing data pipelines. You’ll own projects end-to-end, ship fast, and play a pivotal role in transforming the operations of high-impact teams tackling complex real-world problems.

At Northslope, we believe great software engineers are also great product thinkers. You won’t just write clean code—you’ll help design the right solutions and see them through to production, adoption, and impact.

What We Look For

• User Obsession – You’re laser-focused on making your users successful, even when it means flexing outside your lane. You take pride in building solutions that truly drive business value.

• Full-stack engineering mindset – You’re comfortable jumping between the front-end and back-end as needed. You have experience building modern software / AI applications and RESTful APIs, and can stitch it all together to deliver seamless end-user experiences.

• Frontend Development Skills – You're proficient in TypeScript and React, with a track record of building modern, responsive web applications. You understand component architecture, hooks, state management, and performance optimization. You care about creating intuitive, accessible user interfaces that delight users and work seamlessly across devices.

• Ownership Mentality – You thrive when given autonomy and responsibility. You’re eager to take the lead on problems, with support from the team when needed.

• Track Record of Building in Production – You’ve built and maintained software systems that operate in the real world, ideally with complex or large-scale data. You care deeply about performance, reliability, and user feedback.

• Data Fluency – You're experienced working with structured and unstructured datasets, and know how to translate data into action via your code.

• Collaboration Skills – You can communicate and partner with teammates across disciplines and customers with varying technical backgrounds.

Preferred but not required to be successful

• A bachelor's or master’s degree in Computer Science

• Experience delivering production-grade applications

• Experience with backend frameworks (FastAPI, Node.js)

• Experience with modern CSS frameworks like Tailwind CSS

• Familiarity with frontend build tools and bundlers (Vite, Webpack)

• Knowledge of frontend testing frameworks and best practices

• Familiarity with distributed compute systems like Spark

• Experience with Palantir Foundry and/or AIP

• Exposure to ML or LLM solutions in production environments
  

Company Description

Northslope builds custom products for ambitious organizations that are reinventing their industries - from the largest fortune 500 companies and governments to the smallest startups. We solve our customers' most mission-critical problems with unmatched velocity, bringing their disparate enterprise data into operator-centered workflows that move atoms in the real world and change how people approach their work each day.

We build our products on the Palantir Foundry & AIP platform, the world's first Enterprise Operating system. We focus on enterprise-wide data integration, practical deployment of ML and LLM solutions, and deep understanding of operator's pain points. We build ironman suits for operators, so they can better achieve their mission and deliver more value to the bottom line.

At Northslope, we're built different. Traditional professional services companies are designed for years-long, cookie-cutter projects that stay the same day in and day out. We take pride in being more like a product startup than a traditional services firm. We value velocity, ingenuity, and grit, and we relentlessly focus on delivering tangible outcomes for our customers.

We also have fun. We get to work on big, hard problems, in a fast-paced environment, alongside sharp teammates who help us continuously grow and delight in one another's successes. We offer full benefits and all the perks you'd expect of a modern tech startup, and are a distributed global team with hubs in London, New York, DC and Denver.

Our Principles

• Only Valuable Problems: Not every problem is worth solving. We work on the projects that will significantly improve our customers' bottom lines.

• Outcomes, Not Activity: We create value, not extract it. We focus on our business impact, not racking up billable hours.

• Forward Deployed Engineering: We never build in a vacuum. We go to the heart of the problem and build alongside our users.

• Expand the Possible: AIP & Foundry are powerful. We keep our eyes on the horizon to spot new opportunities for value on the platform.

At Northslope, you'll get to build products that solve mission-critical problems at large customers across a variety of industries, alongside a team of sharp, high-horsepower, caring people who want to win. If you're looking for a fast-paced, high-growth environment and an opportunity to work on a wide array of big problems, we'd love to chat.

Northslope is committed to building a strong, diverse team. We believe teams with a diversity of lived experience, background, and perspectives create better outcomes for our customers and are just more enjoyable to be part of. We are committed to creating and living a culture of diversity, equity, and inclusion throughout our work. We do not discriminate on the basis of race, national origin, religion, disability, pregnancy, age, military status, marital status, genetic characteristics or information, gender, gender identity, gender variance, or sexual orientation.
