What the interview will test

Tech Lead interviews are usually assessed on

• System Design Fundamentals
• Leadership & Influence
• Coding Proficiency
• Prioritization & Trade-offs
• Stakeholder Communication
• Debugging & Root Cause Analysis

Practicing for this role builds your session around these skills, with this posting's own requirements folded in.

What you'd do

• Design and build the front door into finance and its governed contracts: APIs for apps and agents, an event bus for systems that publish, adapters for vendor apps and reports, data-quality gates, and processing that posts every event exactly once, with replay and backfill
• Drive the build of the accounting ledger and engine: an append-only ledger with idempotent posting, a rules framework that turns business events into journal entries, translation into the ERP, and period locks
• Design and build the SDKs and frameworks that finance apps and agents build on
• Build controls into the platform as code: immutable audit trail, maker-checker, scoped access and segregation of duties
• Build and run the production services that other engineering teams call in real time, such as the tax and collections services in the billing flow, and own their reliability: uptime, latency, throughput and correctness targets agreed with those teams
• Shape the platform’s technical direction: architecture, engineering standards and design reviews

What they're looking for

• Strong backend engineering in a statically typed language such as Go, Java or Rust, or Python at scale
• Experience designing and running high-volume, event-driven systems (publish/subscribe, streaming) with idempotent processing, replay and backfill
• Experience designing relational data models and writing SQL for complex, versioned data
• Experience designing APIs, SDKs and service-to-service integrations used by other teams
• Experience building systems with auditability, access control or compliance requirements
• Experience turning requirements from non-engineering partners into technical designs
• Strong written and verbal communication, including design docs

Nice to have

• 10+ years of experience
• Experience building developer platforms or paved paths
• Experience with streaming systems such as Pub/Sub or Kafka
• Experience building with LLMs and agents, including MCP
• Built a ledger, sub-ledger, billing or payments system
• Familiarity with accounting concepts: double-entry, journal entries
• Familiarity with internal controls and audit concepts: audit trails, segregation of duties, change management
• Exposure to ERP or financial systems, such as Workday Financials
