Senior Software Engineer - Full Stack

Amper is an early-stage, VC‑backed SaaS technology company on a mission to modernize manufacturing from the ground up. Our platform is designed to transform legacy shop‑floor complexity into actionable intelligence that empowers teams across the plant to run operations on reality, and help manufacturers reduce costs, increase visibility, and drive efficiency.

Given the highly collaborative nature of this team, we support remote work but have a strong preference for candidates located in the Chicagoland area who are open to coming into the office for in-person collaboration. While there is no set requirement for how often team members come in, being local allows for flexibility to connect in person when it’s most valuable.

The role...

We’re growing our engineering team and we’re looking for a Senior Full Stack Engineer to continue building our customer-facing and internal products.

Working as a full-stack engineer at Amper means working in a wide variety of contexts. We build large APIs as well as microservices. We write a lot of Python. Our front ends are largely React alongside some third party tools. We need to build for the web and for mobile. Sometimes we’re working through the challenges of distributed systems, sometimes we’re tuning a single database query because we need that extra bit of performance.

Being a Senior Software Engineer at Amper also means being a “product person.” Our engineers don’t just move tickets from pile A to pile B. Led by a Product Owner, you'll help us work through new ideas and figure out the best way to implement them.

You’ll enjoy working at Amper if you:

• Have a strong appetite for the unfamiliar; that includes technical content as well as solving problems our customers face

• Believe that being helpful and humble are just as important as technical know-how

• Can teach the things you know well, and acknowledge what you can learn from others

What we're looking for:

• At least 7 years of professional experience building and maintaining complex software systems, with significant time spent on a B2B SaaS platform product. This is a must-have for success in the role.

• Deep technical expertise in developing both large APIs and smaller microservices, with a proven ability to evaluate architectural trade-offs and guide others through implementation.

• Advanced proficiency in Python (or another modern object-oriented language) with the ability to produce clean, maintainable, and testable code.

• Extensive experience with relational databases, including performance tuning, query optimization, and applying strategies like sharding or schema redesign when appropriate.

• Strong working knowledge of distributed systems, including containerization, message queues, and parallel processing, along with the ability to apply these concepts in production environments.

• Full-stack development experience, with deeper expertise and enjoyment working on the back end while remaining comfortable contributing to front-end development (React) when needed.

• Experience delivering solutions across platforms, including web and mobile, with an emphasis on performance, scalability, and reliability.

• A product-oriented approach with a history of collaborating closely with Product Owners to define, design, and deliver customer-focused solutions.

• Excellent written and verbal communication skills and a collaborative mindset for working across engineering and non-engineering teams.

• A track record of thriving in fast-paced environments, ideally within early-stage, high-growth companies or similarly dynamic settings.

• A commitment to continuous learning and knowledge sharing, both mentoring others and seeking out opportunities to grow your own skills.

Preferences

• Knowledge of DevOps tooling and practices (CI/CD, Monitoring)

• Experience deploying infrastructure (Infrastructure-as-code, cloudformation, ansible)

Our Candidate Selection Process

We aim to keep our hiring process quick, transparent, and mutually beneficial — giving both you and our team the opportunity to learn enough about each other to make a confident decision. Our process typically includes:

• CoderPad Exercise (30–40 minutes) – A short, timed exercise to understand your technical approach and problem-solving skills.

• Hiring Manager Interview – A deeper discussion about your experience, the role, and how we might work together.

• Technical Paired Interview – Collaborate with a member of our team on a real-world problem to see how we work in practice.

• References – We connect with a few people who have worked closely with you to learn more about your strengths and working style.

• Offer – If it’s a great fit on both sides, we’ll extend an offer and look forward to welcoming you to the team.
