Back End Engineer

At Emi Labs we are on a mission to increase Frontline Workers’ access to professional opportunities.   This is a 2.7 billion population that accounts for 80% of the world’s workforce. They are digitally invisible, as there’s little to no data available on who they are, their career history, or their skill set, limiting their access to professional opportunities and growth. We're here to transform this by building the infrastructure to make Frontline Workers visible.    Our first step to achieving our mission is to transform the recruiting experience into an easy, human and fair process, for both candidates and companies with high-volume job openings. Emi, our main product, is an A.I. recruitment assistant that enables companies to engage in a conversation with each applicant to detect interested and qualified individuals while saving Recruiters a huge amount of time by automating tasks such as screening, validating skills, scheduling interviews, and collecting documents.    We were part of Y-Combinator's Winter 2019 batch and in 2022 we have raised an $11M funding round co-led by Merus Capital and Khosla Ventures.
About our Interview Team   An interview is the most crucial moment in a talent acquisition process. The Interview Team is responsible for smart interview scheduling and feedback reception. In a context where frontline candidate assistance to interview is very low (10% - 50%), building tools to make effective scheduling has a great impact on both recruiters and candidates.       What you'll be doing   As a Backend Engineer on the Interview Team, you’ll design and build the orchestration of several modules involved in interview scheduling and execution. In addition to strong backend fundamentals, this role expects a hands-on approach to leveraging AI tools and developing AI-powered agents to automate workflows, reduce manual effort, and increase the team’s overall efficiency and impact. You’ll work across system architecture, high-level programming, testing, and systems integration, while continuously exploring how AI can be applied to improve internal processes, developer experience, and product capabilities.

Tasks

• Design and implement scalable backend solutions, ensuring technical feasibility and long-term maintainability.
• Research, evaluate, and apply AI tools and frameworks to automate workflows, repetitive tasks, and operational processes within the team.
• Develop and maintain AI-powered agents to support areas such as testing, monitoring, data validation, and internal tooling.
• Solve production issues with a strong focus on candidate experience and system reliability.
• Ship code to production frequently (on a weekly basis).
• Monitor service performance and proactively take action when issues or optimization opportunities arise.

Sample Projects

• Recurring interview creation and configuration.
• Automatic interview creation triggered by client vacancies.
• Maintain candidate engagement while waiting for the interview day.
• Automate end-to-end functional and regression tests using AI agents.
• Build internal AI-driven tools to orchestrate, validate, and monitor interview scheduling workflows.
• Implement AI-assisted observability or alerting mechanisms to detect anomalies in interview flows.

What we're looking for

• 4+ years of experience as a backend developer, software engineer, or in a related role.
• Strong backend development experience (Node.js preferred).
• Experience designing, discussing, and implementing technical solutions.
• Hands-on experience researching, evaluating, and using AI tools (e.g. LLM-based tools, AI agents, automation frameworks) in a professional or advanced personal context.
• Interest and ability to build AI-driven automation for workflows, testing, and operational tasks.
• Proactive, passionate, and resilient mindset, comfortable working in a fast-growing and imperfect environment.
• Ability to collaborate and communicate effectively with multiple stakeholders, both technical and non-technical.
• Strong written and verbal communication skills.
