Position Overview

We're seeking an experienced Senior Software Engineer to join our team in developing distributed, cutting-edge applied AI systems. This is a full-time position working directly with our engineering team to drive technical innovation and mentor mid-level and junior engineers.

What You'll Do

• Contribute to the architecture and development of production-grade distributed microservice systems running on Linux

• Drive technical initiatives to advance our service mesh, contract-first APIs, and inter-service communication patterns

• Build scalable data processing pipelines and high-throughput service infrastructure

• Design and evolve protobuf contracts and gRPC service definitions across the platform

• Provide technical guidance to junior team members

What We're Looking For

• 10+ years of professional experience developing distributed backend systems on Linux

• Deep curiosity for all software and systems architecture topics

• Expert-level Python programming and software architecture skills

• Strong system design skills with a focus on service boundaries, API contracts, and fault tolerance

• Fluency operating in Linux environments - comfortable living in the shell, reading logs, and reasoning about process, network, and filesystem behavior

• Excellence in technical communication and documentation

Required Technical Skills

• Expertise in prompt engineering and AI-assisted development as a daily practice - Claude Code, Augment, Copilot, or equivalent is a force multiplier in your workflow, not a novelty

• Expertise in designing and operating microservice architectures at scale

• Deep experience with gRPC and Protocol Buffers - schema evolution, streaming RPCs, interceptors, and contract-first development

• Proficiency with version control and CI/CD practices

• Experience with containerized deployments (Docker on Linux hosts), service discovery, and distributed computing

• Strong grasp of observability: distributed tracing, structured logging, and metrics

Highly Competitive Candidates Will Also Bring

• Previous experience in manufacturing, industrial automation, or quality control systems

• Experience with monorepo build systems (Bazel, Buck, Pants) and polyglot protobuf code generation

• Familiarity with backwards/forwards compatibility patterns and API versioning at scale

• Experience with real-time processing and edge computing constraints on resource-constrained Linux devices

• Experience with configuration management and infrastructure-as-code (Ansible, Terraform) for Linux fleet operations

Why Join Us?

• Work with cutting-edge technology in a high-impact industry

• Meaningful early-stage equity at a late seed-stage company

• Competitive compensation and benefits package

• Professional development and learning opportunities

• Opportunity to shape manufacturing technology that impacts American industry
