Position overview

We are seeking a Full Stack Engineer who builds with AI in the loop — both as a daily development practice and as a product capability. You are fluent with coding agents (Claude Code, Cursor, Copilot) and ship faster because of them, not despite them. You understand how to design, prompt, evaluate, and operate LLM-backed features in production — including model selection, context engineering, evals, guardrails, and cost and latency tradeoffs.

Beyond AI, you have deep Golang and React/TypeScript expertise and own features end-to-end: from understanding business requirements, through writing and testing code, to deployment and production monitoring. This role requires strong autonomy, proactive communication, and the ability to deliver reliable, scalable solutions in a modern cloud environment.

This position operates according to the CET time zone.

Responsibilities

• Design and ship LLM-powered product features: prompt design, retrieval, tool and function calling, structured outputs, streaming, evaluation harnesses, and guardrails.
• Operate AI features in production: monitor quality, latency, cost, and failure modes; iterate on prompts, models, and architectures based on real usage.
• Use AI coding tools (Claude Code, Cursor, Copilot) as a core part of your workflow to accelerate delivery without compromising code quality.
• Design, develop, and maintain backend services using Golang and frontend applications using React/TypeScript.
• Collaborate with product managers, designers, and other engineers to translate business requirements into technical solutions.
• Implement event-driven architectures leveraging Kafka for real-time data processing.
• Manage and optimize AWS environments, ensuring scalability and reliability.
• Define and maintain infrastructure using Terraform and deploy services in Kubernetes clusters.
• Build and maintain CI/CD pipelines in Jenkins for automated deployments.
• Ensure high-quality code through comprehensive testing and code reviews.
• Monitor application performance and troubleshoot issues in production environments.
• Contribute to UI/UX improvements and ensure seamless integration between frontend and backend.

Requirements

• Demonstrable production experience shipping LLM-powered features. Be ready to walk through a feature you built: prompts, evaluation approach, failure modes you fixed, and how you measured success.
• Hands-on with at least one major LLM provider's API (Anthropic, OpenAI, AWS Bedrock, or equivalent), including streaming, tool use, and structured outputs.
• Daily use of AI coding assistants in your workflow; able to articulate where they help, where they hurt, and how you maintain code quality.
• Strong, in-depth knowledge of Golang.
• Experience delivering complex backend systems from design to production.
• Solid background with Kafka and event-driven architectures.
• Hands-on experience managing AWS environments.
• Proficiency with Terraform for infrastructure-as-code.
• Experience deploying and operating services in Kubernetes.
• Building CI/CD pipelines in Jenkins.
• Proven ability to ensure quality through comprehensive testing.
• Strong proficiency in React and TypeScript.
• Experience contributing to front-end features, UI components, and client-side logic.
• Ability to seamlessly integrate frontend with backend services.
• Excellent English communication skills, written and spoken.
• Self-driven and able to work independently while managing workload effectively.

Nice to have

• Experience with agent frameworks, multi-step tool-use loops, or RAG systems at scale.
• Built or maintained an evaluation pipeline (offline evals, LLM-as-judge, human review loops).
• Open-source contributions, published writing, or talks on applied AI engineering.

About Us 
We’re building an AI-driven hiring platform designed to transform how organizations evaluate talent. Our product delivers real-time candidate insights, identifies skill gaps, and recommends development pathways - while enabling recruiters to efficiently identify top performers through data-driven decision-making. 

About the Role 
We’re looking for a Psychometrician to join us as a part-time, ongoing consultant. This role combines strategic advisory with hands-on work, ensuring our assessment methodologies are scientifically sound, fair, and compliant with professional and legal standards. 
You’ll collaborate closely with product and engineering to validate and improve our AI-driven assessment systems. 

What You’ll Do 
 

• Evaluate and improve candidate assessment frameworks; 
• Design and run validation studies (criterion-related, construct, content validity); 
• Establish and monitor reliability metrics (e.g., internal consistency, test-retest); 
• Ensure AI-driven scoring aligns with psychometric best practices; 
• Audit algorithms for bias, fairness, and adverse impact; 
• Support calibration and continuous improvement of ranking models; 
• Ensure alignment with EEOC, APA, and SIOP standards; 
• Conduct adverse impact analyses and assess subgroup differences;  
• Recommend and implement bias mitigation strategies; 
• Define and track key measurement KPIs (validity, reliability, fairness); 
• Translate technical findings into clear, actionable insights; 
• Prepare documentation for audits, certification, and external validation. 
  
  Success Metrics 
• Assessment validity and reliability clearly established and documented; 
• Fairness and bias benchmarks defined, tracked, and improved over time; 
• Readiness for certification or third-party validation within agreed timelines. 

Core Requirements 
 

• Master’s or PhD in Psychometrics, Industrial-Organizational Psychology, Statistics, or a related field; 
• 5+ years of experience in assessment validation, ideally in hiring or talent assessment; 
• Strong knowledge of Item Response Theory (IRT) and/or Classical Test Theory (CTT); 
• Experience designing and executing validation studies; 
• Hands-on experience with adverse impact and fairness analysis; 
• Strong analytical and problem-solving skills; 
• Ability to work independently in a remote, flexible environment; 
• Clear communication skills, especially with non-technical stakeholders. 

Nice to Have 
 

• Experience with AI/ML-based hiring or assessment systems;  
• Background in HR tech or talent analytics; 
• Experience supporting audits, certification, or compliance processes;  
• Academic or research affiliation. 

Engagement Details 
 

• Part-time, ongoing consulting role; 
• Fully remote with flexible hours; 
• Mix of strategic advisory and hands-on work. 

We're building an AI system that reads content and automatically determines:
 

1. Whether it contains a paid endorsement (yes / no)
2. What type of endorsement it is, based on our classification spec
3. Which brand it refers to — matched against our existing brand database, with a suggested new brand name when there's no match
    

We already have a labeled set of examples across the different endorsement types that you can use for training and evaluation. 
 

What you'll do

• Build a classification pipeline that flags paid vs. non-paid endorsements and categorizes endorsement type per our specification
• Build brand matching (entity resolution) against our database using fuzzy and/or semantic matching, with a "suggest a new brand" fallback when nothing matches
• Use our labeled examples to train and/or tune the system, and set up an evaluation framework so we can measure and improve performance per task
• Process large volumes of entries efficiently and cost-effectively

• Document the approach and hand off a maintainable system

   

What you should have

• Strong experience building NLP / text-classification systems
• Hands-on work with modern LLMs (e.g., Claude, GPT) — prompt engineering, structured outputs, and/or fine-tuning
• Experience with entity resolution / record linkage — fuzzy or semantic matching, embeddings, vector search
• A rigorous, evaluation-driven approach — you measure performance properly rather than by feel
• Comfort with our stack: Python, SQL, working with APIs and a database

At any given moment, thousands of servers are consuming 150+ billion mobile app events, crunching our users’ data, serving requests, and communicating on a massive scale.

To maintain the universe we call AppsFlyer, we practice modern production operations with a complete self-serve CI/CD platform, a highly integrated observability stack for our micro-services, backends, and infrastructure, a culture of ownership and eagerness for quality.

The Analytics group is responsible for showing our clients the stories their data is telling. Through complex aggregation, mission-tailored analytical databases, and carefully crafted APIs we are able to provide slice-and-dice analysis in our beautiful dashboards and through the use of external integrations.

You will design and implement data pipelines using Apache Airflow and Spark, choose and optimize analytical databases, and integrate new components in our hybrid microservices environment. You will collaborate with product managers and cross-functional teams, troubleshoot production incidents, and influence our migration toward Google Cloud and BigQuery.
