Every generation gets one protocol moment. TCP/IP. SMTP. HTTP. A small team writes the spec, ships the first implementation, and fifteen years later the entire world runs on it without knowing who built it. We’re at that moment for economic coordination.
AI agents are being deployed everywhere, right now — negotiating, committing, paying, settling on behalf of every company that wants to stay competitive. In a few years there will be billions of them. The problem: there is no protocol for what happens between them. An agent can be smart. It cannot be governed. It can pay. It cannot make a payment conditional on something that actually happened. Agents from different organizations can talk. They cannot safely coordinate across company boundaries. Nobody has built that layer. We’re building it.
Blue is a protocol for structured, verifiable, multi-party agreements that execute deterministically, leave an immutable audit trail, and run on existing financial rails. Smart contracts without blockchain. Governance without a platform. Trust without a middleman.
PayNotes — programmable payments with conditional capture, milestone releases, automatic refunds, and partner settlement. Logic embedded directly into money movement.
MyOS — orchestration layer for merchants and agents. Agentic workflows and cross-platform trust, without touching the protocol directly.
The Role
You will own features end-to-end — from the React component a merchant clicks to the Lambda function that settles their transaction to the AWS infrastructure that keeps it all standing. No handoffs between "front" and "back". No waiting for someone else to unblock you.
This is a high-trust, high-autonomy role. You'll work directly with the founding team, your decisions will ship to production fast, and yes — you'll be on the hook when something breaks.
What you get?
Competitive B2B compensation based on experience
Equity — own a piece of what you build
Fully remote work in an async-first environment
Direct collaboration with the founding team
High autonomy and fast decision-making
Small team, outsized impact
Work on technology that is genuinely novel
End-to-end ownership across product, systems, and production
Protocols don’t get built by committees. They get built by small teams who understood the problem before anyone else did.
What You'll Do
Design and ship full-stack features across payments, document workflows, and agent orchestration
Build and maintain stateful systems that demand idempotency, auditability, and safe retry logic
Own AWS infrastructure — architecture decisions, serverless systems, IaC (SAM / CloudFormation), monitoring, cost, and security
Work with PostgreSQL-backed services and event-driven components
Use modern AI tooling (LLMs and coding agents) to accelerate development and experimentation
Requirements
We're not looking for someone to fill a seat. We're looking for an engineer who gets it — who sees a distributed system and immediately starts asking the right questions about state, consistency, and failure modes. Someone who ships and takes pride in what they ship.
7+ years of experience building and shipping production systems as a full-stack engineer
Strong backend expertise in Node.js and TypeScript — not just building APIs, but designing systems that stay correct under load and failure
Strong frontend skills with React, including the ability to build polished, production-ready product interfaces without depending on a separate frontend team
Solid understanding of distributed systems: consistency, state transitions, concurrency, retries, failure handling, and eventual consistency trade-offs
Proven experience building stateful, event-driven systems where correctness matters
Hands-on experience with AWS in production, especially Lambda, API Gateway, SQS/SNS, EventBridge, IAM, CloudWatch, RDS, and serverless architecture patterns
Strong experience with Infrastructure as Code, ideally AWS SAM and CloudFormation
Strong PostgreSQL skills, including schema design, transactions, indexing, migrations, and performance tuning
Experience designing systems with idempotency, auditability, and deterministic execution built in from the start
Ability to debug and stabilize production systems end-to-end — across application code, infrastructure, data, and runtime behavior
Strong grasp of observability, monitoring, logging, alerting, and incident response
Good judgment around security, reliability, and cloud cost, with the ability to make pragmatic architectural trade-offs
Ability and willingness to own features end-to-end — from product shaping to implementation, deployment, and post-release accountability
Comfortable operating in a high-trust, high-autonomy environment with very little hand-holding
Strong product and engineering judgment — you ask the right questions early, and you do not need heavy process to move fast responsibly
Comfortable using LLMs, coding agents, and modern AI tooling as part of your development workflow
Fluent English and Polish, written and spoken
Nice to have
Experience in payments, fintech, ledgering, settlement, or transactional systems
Experience with document workflows, approvals, or multi-party business processes
Experience working on systems of record or products with strict audit/compliance expectations
Experience at an early-stage startup or in a small, high-talent engineering team
Experience building products where reliability and system correctness matter more than shipping surface-level features
