Job summary

Zeo Consulting is seeking an architecture-focused software leader to design system boundaries, data models, and contracts that work across brand experiences while keeping determinism where needed. The role emphasizes agent-driven development and rigorous verification before merging, with a strong emphasis on typed schemas and observability.

Ideal candidates will drive architecture decisions in collaboration with product and engineering, and will craft specifications, RFCs, and invariants to

Qualifications

• 8+ years of software development experience.
• Proficiency with TypeScript and Python.
• Experience directing AI coding agents with rigorous review and verification practices.
• Experience building component-driven front-ends and data-heavy internal consoles.
• Experience with Postgres, including migrations, indexing, and query performance diagnosis.
• Experience with containers and production deployments.
• Experience with monorepos and multi-repos.
• Experience building CI/CD pipelines (merge gates, reproducible builds, etc.).
• Experience owning system architecture decisions in production.
• Experience implementing protocols against specifications and conformance tests.
• Experience with messaging APIs (carrier, WhatsApp, chat).
• Experience instrumenting systems and reading traces for observability.
• Ability to learn unfamiliar frameworks quickly.
• Ability to hand-code and deeply review AI-generated code.
• Deep understanding of typed schemas as a single source of truth and generated clients.

Responsibilities

• Define service boundaries, data models, and contracts between components.
• Design seams for local and hosted code without a rewrite.
• Turn fuzzy capabilities into clear models and rules.
• Apply MIT concept design methodologies to agentic system design.
• Design abstractions to keep behavior consistent across brands.
• Decide where systems must be deterministic and where human judgment applies.
• Collaborate with founders on architecture decisions.

Job description

This is an architecture role that writes code, not a coding role that occasionally diagrams.

The hard problems here are not framework problems. There are questions like

What is the right abstraction for behavior that must stay identical across brands with wildly different experiences?

Where does a system have to be deterministic and reproducible, and where can human judgment live?

What belongs in a shared contract versus a local implementation?

How do you make a system's invariants checkable rather than aspirational?

We need someone who thinks in systems and concepts first, and who can then build the thing. Specifically

System architecture and concept design

Define service boundaries, data models, and contracts between components

Design seams that let the same code run locally and hosted without a rewrite

Turn fuzzy capabilities into clear models of core entities and rules

Apply MIT concept design methodologies to agentic system design

Design abstractions that keep behavior consistent across brands with very different experiences

Decide where systems must be deterministic and where human judgment can apply

Make architecture decisions alongside founders with product and engineering backgrounds

Verification and documentation

Plan up front how each system will prove its correctness, rather than retrofitting tests

Make system invariants checkable through code and tests

Write specifications, decision records, and product invariants in RFC 2119 language

Agent-driven development

Direct AI agents to build features and review their output in depth before merging

Write specs that agents can execute and reviewers can check

Maintain agent instructions and skills as first-class artifacts

Run independent adversarial reviews before opening pull requests

Catch plausible but wrong results (e.g. silent safety gates, empty version pins, hollow dependency directories)
