[Hiring] Senior Software Engineer, Agents @Replicant

Role Description

As a Senior Software Engineer, Agents on our Delivery team, you make that happen for specific customers:

• Own AI agents for your assigned customers across the full lifecycle: discovery, design, build, evaluation, launch, and live operation.
• Sit with customers, map their workflows, and translate ambiguous business goals into a concrete agent scope.
• Uncover the customer's real business rules, including the unwritten ones, and pin them down so the agent enforces that business logic strictly.
• Design and write the agent's prompts, instructions, and conversation flows, and iterate against evals, real transcripts, and your own product taste.
• Wire the agent into customer systems (CRMs, ticketing, internal services): call their APIs as tools, shape inputs and outputs, and handle auth, errors, and edge cases.
• Build test sets from real cases covering not just the happy path but unhappy paths, edge cases, and hallucination risks.
• Monitor live conversations and tool-call health, debug from logs and transcripts, and ship fixes under pressure.
• Feed recurring patterns and missing capabilities back to Product for future improvements.

Qualifications

• Customer-facing strength: Ability to converse credibly and earn trust quickly with customers.
• Integration fluency: Understand and shape integration patterns, handle auth, errors, and edge cases.
• Prompt and instruction craft: Shape LLM behavior through structure, instructions, and examples.

Requirements

• General-purpose coding experience (TypeScript, Python, SQL).
• Prior forward-deployed, solutions engineering, or customer-embedded work.
• Conversational AI, voice, or contact center domain experience.
• Experience with LLM evaluation tooling and observability.
• A computer science degree or a software engineering title is not required.

Benefits

• In-person connection that counts: company-wide offsites and smaller team gatherings.
• Tech & learning stipend: Conferences, books, courses — we’ll fund them.
• Remote by design: Distributed work with no guilt about life events.
• Health & wellness: Flexible vacations, paid sabbatical after 5 years, comprehensive benefits.
• Compensation that matches your impact: Competitive salaries.
• Equity with upside: Shared ownership in a fast-growing AI company.
