Principal Software Engineer (AI/Full-Stack) - Remote, Part-time/Full-Time Job

The Role
As a Principal Engineer at AI REV, you aren’t just writing code; you are defining how we bridge the gap between Large Language Models, Machine Learning Models and rigorous software engineering. You will own the architecture of scalable systems that serve global organizations, working with high autonomy to deliver solutions that are robust, secure, and blazingly fast.

You will operate at the intersection of Systems Engineering (Go/Python) and Applied AI. You will partner directly with clients to deconstruct ambiguous problems and ship solutions that define the state of the art.

What You’ll Do
- Architect Production-Grade AI Systems: You will design and ship highly performant, distributed backends (primarily in Go) that orchestrate complex AI workflows. You will move beyond "demos" to build resilient systems capable of handling sensitive data at scale.
- Drive Technical Strategy: You will have complete ownership of the technical roadmap for your projects. You will make high-stakes decisions regarding infrastructure (K8s, Cloud), architectural patterns, and the integration of emerging LLM capabilities.
- Elevate Engineering Craftsmanship: You will set the standard for code quality, DevOps practices, and system design. You will act as a mentor to other engineers, fostering a culture of technical excellence and continuous learning.
- Solve the Unsolvable: Whether it’s optimizing latency for real-time voice agents or ensuring context retention in massive datasets, you will tackle the hardest technical bottlenecks in the Agent Development Life Cycle.

Example Projects
- Enterprise-Scale Conversational Agents: Architecting a human-like assistant for a global organization that handles sensitive account verification and data retrieval. We automated >70% of 24/7 requests by combining secure RAG pipelines with K8s auto-scaling.
- Real-Time Voice Intelligence: Building a low-latency voice assistant for sales and support that performs instant transcription, context analysis, and live objection handling, drastically increasing conversion rates.
- AI for Social Good: Developing a matching system for a foster care agency. We utilized ML to improve the accuracy of matching children with foster families, streamlining operations to help children find homes faster.Our Values
- Impact Over Activity: We focus on outcomes. We trust you to manage your time and deliver excellence, whether you work from a beach in Bali or our office in Warsaw.
- Sustainable Velocity: We reject "crunch culture," but we also reject stagnation. We believe that a calm, focused environment is the fastest way to build perfection. We take the time to architect it right the first time so we can maintain a high, steady speed without the stress of technical debt.
- Radical Transparency: We share knowledge openly. We believe that the best idea should win, regardless of who proposes it.
- Craftsmanship: We take pride in our code. We review thoroughly, test rigorously, and refactor courageously.
- Social Mission: We believe technology is a lever for good. By working here, your code directly funds the education of young people who need it most.

What We Offer
- Top-of-Market Compensation: A contract tailored to your experience level.
- Culture: Work alongside engineers who have built systems for NASA, Google, TikTok, and Microsoft.
- Rapid Growth: A fast track to leadership positions with regular 360° feedback and mentorship.

What We Offer
We are looking for talents, not just employees.

Fill in the form or send your CV to [email protected]. Instead of a cover letter, tell us briefly about a technical problem you solved recently that you are proud of.

We strive to evaluate all applicants consistently without regard to background. If you are an exceptional engineer who loves to build, we want to hear from you.

What You’ll Bring
- Elite Engineering Fluency: You have a proven track record (5+ years) of building and scaling complex backend systems. You are proficient in Go or Python.
- Systems Thinking: You understand the full stack, from the database (SQL/NoSQL) to the container (Docker/K8s) to the cloud (AWS/GCP/Azure). You design for failure and build for scale.
- AI/LLM Pragmatism: You may not be a research scientist, but you know how to engineer around the non-deterministic nature of LLMs. You understand prompt engineering, RAG, and model integration.
- High Agency & Founder Mindset: You don’t wait to be told what to do. You identify problems, propose solutions, and execute with intensity.
- Communication Mastery: You can explain complex architectural trade-offs and business value to a client’s stakeholders. (English proficiency is required).

AI REV is not just a technology consultancy; it is a community of people who believe that technology can make the world a better place. We build high-performance, mission-critical AI systems for international enterprises and dynamic startups. But our "why" is different: we funnel a portion of our revenue into the AI REV Foundation, funding programming education for youth in underserved regions. We are building a team of the world’s best problem solvers. Our engineering DNA is composed of alumni from NASA, Google, Microsoft, TikTok, and NVIDIA. We don’t do "shelfware." We build complex, production-grade systems that solve hard business problems and, in turn, change human lives.
