Principal Architect (Seattle)

We're hiring a Principal Architect

Hybrid Seattle preferred / Remote OK. Full-Time.

Boundless is a Series C legal tech company based in Seattle, backed by Foundry Group and Silver Lake. We build tech-powered immigration solutions for corporate HR teams and individuals navigating family and naturalization cases. We are developing an AI-powered services firm.

Why this role exists

We are rebuilding our software platform and engineering infrastructure from the ground up, and we need a Principal Architect to lead that transformation and set the technical vision that ties it together.

You will have a real customer base and a real platform — and the autonomy to reshape both — on day one. We are looking for someone who loves the speed and impact of startups, but wants their work to be immediately scaled on day one.

Immigration is complex, with endless edge cases and global scale. We are building intelligent automation, orchestration, and decision‑making to support the agentification of legal workflows, with the checks and balances required to ensure accuracy in a regulated domain and to enable the lawyers who ultimately own legal decisions. The challenge is systems and data infrastructure that can handle this complexity without sacrificing accuracy, observability, or speed, at the scale required to reliably serve thousands of people every year.

We are looking for someone who can hold the whole technical picture: the platform, the AI layer, the data infrastructure, the engineering infrastructure — and how they interact. Someone who makes hard calls, thinks in years not months, and partners with our engineering team to build a durable, world‑class AI platform that helps millions of people achieve their immigration dreams.

Responsibilities

• Own the platform architecture end to end: service boundaries, API design, multi‑tenancy, data modeling, and the shift to agent‑orchestrated legal work.
• Design the AI layer: how LLMs, retrieval systems, and structured tools connect to case data; how we evaluate quality; how we handle failure modes that matter in a regulated domain.
• Build and own foundational agent infrastructure that product teams use to deploy, monitor, and manage agents independently.
• Define how context is structured and managed: what gets persisted, how customer and session state is scoped, and how agents share or isolate domain knowledge.
• Build agents that handle legal tasks, communications, data hygiene, payments, and the full operational surface of an immigration case, from intake to government submission to resolution.
• Define how data moves, from transactional systems to the warehouse to the operational tooling case managers and legal teams rely on every day.
• Transition our engineering infrastructure into a software factory, overhauling dev processes, systems, tools, and culture in partnership with product and engineering.
• Be the senior technical voice in design reviews and hard tradeoff conversations. Write architecture decision records that give the team durable context.
• Mentor engineers on architectural thinking by doing the work visibly and giving direct feedback on design proposals.
• Ship code and lead from the front.

Qualifications

• 10+ years in engineering, with meaningful time as a principal, staff, CTO, or architect‑level IC.
• Own architectural decisions on production systems people depend on.
• Think in systems and hold the platform, AI layer, data infrastructure, and business constraints in your head.
• Built systems with autonomy and speed, delivering impact on thousands of customers.
• Make decisions quickly, and know the impact of reversible vs. costly calls.
• Shipped AI into production; have knowledge of retrieval, evaluation, latency, and when to use AI versus other tools.
• Build systems where agents and humans work in harmony without overbuilding.
• Write clear documentation that helps engineers make decisions when you are not present.
• Experience in a domain where correctness matters: legal, healthcare, financial services, or public safety.
