Software Architect

Software Architect - Agentic AI Platform

Replai | Tel Aviv (On-site) | Full-time

About Replai

Replai is an AI platform that helps large enterprises understand, maintain, and evolve their mission-critical and most complex software systems. The platform analyzes source code, runtime traces, tickets, documentation, and internal knowledge to build a living model of how an organization's software actually works - turning years of accumulated knowledge into an accessible, ready-to-use institutional knowledge base.

Replai helps engineering teams navigate complex environments, modernize legacy systems, and build new capabilities with greater speed and confidence - even as the few people who hold pieces of the puzzle become harder and harder to find.

We work with global banks, insurers, and enterprises operating COBOL, Oracle Forms, Java, .NET, proprietary languages, and other legacy stacks at 100M+ lines of code.

Founded by two serial entrepreneurs (Meta, Sapiens, JFrog, CrazyLabs), Replai is already in production at some of the world's largest enterprises, and recently closed its first funding round.

The Role

We're looking for a Software Architect to join the Core team and define the technical foundations of the platform - the systems that enterprises already bet their most critical operations on.

You'll have real ownership of the architecture end-to-end, from early design through production, with direct access to customers and product decisions.

What You'll Work On

• Designing scalable data pipelines and knowledge graph infrastructure

• Setting technical direction for LLM orchestration and agentic workflows

• Developing AI agents that understand and operate on complex, multi-language codebases

• Making high-leverage architectural calls on hard problems, with real business impact

What We're Looking For

• Prior experience on a core team at an early-stage startup

• Proven experience architecting complex, large-scale systems - ideally in high-throughput or data-intensive environments, with a track record of decisions that held up as the product scaled

• Strong background in at least one of: agentic frameworks and LLM orchestration, or knowledge graph/data infrastructure

• Comfortable moving between big-picture design and hands-on implementation, across multiple languages and tools

Primary stack: Python and Go.

Why Join Now

The people joining at this stage will define the product, the engineering standards, and the culture - not inherit them. You'll work directly with the founders, have full visibility into the business, and design systems that genuinely matter.

We work from the office in Tel Aviv (Azrieli Towers).

Compensation

Competitive salary based on experience, with meaningful flexibility for strong candidates. Equity included.
