Platform Architect

Embedding VC; San Francisco (CA); On-site; USD 250,000 - 350,000; Full time

Job summary

Embedding VC is seeking a Platform Architect to own version engineering and module governance for a modular financial cloud platform. You will define locked, tested site configurations and manage reproducible builds across 2000+ services.

The role focuses on build systems, dependency analysis, and cross-site change control in a regulated, multi-region environment.

Qualifications

• 10+ years in large-scale distributed systems / platform infrastructure.
• Deep expertise in build systems and dependency management at scale.
• Experience with reproducible build engineering and artifact provenance.
• Knowledge of version resolution, lockfile pinning, and semantic versioning governance.
• Background in multi-region, multi-tenant platforms handling regulated workloads.

Responsibilities

• Design the version set model with locked module combinations and compatibility matrices.
• Architect reproducible build pipelines with hermetic environments and provenance.
• Maintain a live dependency graph across 2000+ services and perform impact analysis.
• Define monorepo governance, CODEOWNERS, and cross-module change protocols.
• Implement GitOps deployment across multiple sites with scalable strategies.
• Develop a four-layer testing framework and automated enforcement for deployments.

Job description

About the Role

The company operates 2000+ microservices deployed across dozens of compliance-regulated sites globally. They are transforming this into a modular financial cloud platform - organizing services into 50-100 independently versioned business modules, where each compliance site is a version set (a pinned, validated combination of module versions).

As Platform Architect, you will own the version engineering and module governance architecture - the system that ensures every deployment is reproducible, every change's blast radius is computable, and every site composition is a known-good state. This is fundamentally a build systems + dependency management + change propagation problem at financial-grade reliability.

Key Responsibilities

• Design the version set model: each site defined as a locked, tested combination of module versions (analogous to a Bazel workspace snapshot or Cargo.lock), with version compatibility matrices and automatic constraint solving

• Architect reproducible build pipelines: any module at any version produces byte-identical artifacts regardless of when/where it's built; hermetic build environments, content-addressable artifact storage, SLSA Level 3+ provenance

• Build and maintain the live dependency graph spanning 2000+ services: static analysis (code/API/schema) + runtime analysis (traffic-weighted call patterns), transitive dependency resolution with automatic conflict detection

• Design the monorepo + package ownership governance model: clear module boundaries via DDD, CODEOWNERS enforcement, cross-module change protocols, module boundary enforcement tooling (lint rules, CI checks, architectural fitness functions)

• Architect change impact analysis systems: given any PR, compute which modules/sites/tests are affected; selective test execution (run only dependency-graph-proven relevant tests); change confidence scoring (blast radius + coverage + stability - risk grade)

• Design the GitOps-driven multi-site deployment model: site config repos declaring module versions + compliance parameters, automated deployment strategies (patch auto-deploy, minor with review, major with migration plan, security force-push)

• Architect the four-layer testing framework: Module self-test - Platform compliance tests (parameterized by country) - Cross-module integration tests - Site-specific tests, with automated coverage enforcement that blocks deployments when gaps are detected

Major Requirements

• 10+ years in large-scale distributed systems / platform infrastructure

• Deep expertise in build systems and dependency management at scale: Bazel, Buck, Pants, Nx, or equivalent (1000+ packages)

• Production experience with reproducible build engineering: content-addressable storage, hermetic builds, deterministic CI, artifact provenance (SLSA)

• Experience building dependency graph tooling: static/runtime dependency analysis, impact computation, selective testing

• Strong background in semantic versioning governance across large service fleets: version resolution, compatibility constraints, lockfile-style pinning

• Experience with API contract evolution: protobuf/gRPC versioning, schema evolution strategies, contract testing

• Experience with multi-region/multi-tenant platform architectures serving regulated workloads

• Track record of migrating monolithic systems to modular architectures without business disruption

• Preferred: Experience with Amazon's internal VersionSet / Brazil build system / Apollo deployment, or similar systems at Google (Blaze/Bazel), Meta (Buck/Configerator)

• Preferred: Background at Stripe or Adyen - multi-country financial platform with compliance parameterization
