Equals5 is a leading Healthcare Marketing SaaS for Pharma and Life Sciences. Our platform leverages exclusive NPI-level targeting technology to help brands reach healthcare professionals across 20+ channels with precise, user-level reporting.

The Role

We are looking for a Senior Data Engineer to join the Identity team at Equals5. This is not a standard ETL role. We are building a dynamic data ecosystem where AI is deeply integrated—both as a productivity multiplier and as a core component of our data processing logic for identity data enrichment and data scoring.

You will own the infrastructure that handles over 10,000 executions per minute, ensuring stability, scalability, and data integrity. You will work with a modern stack on Google Cloud Platform, utilizing Cloud Functions and Kubernetes.

We are looking for an engineer who improves infrastructure, automates everything, and is eager to implement LLM-based logic directly into high-load data flows.

Responsibilities

• AI-Driven Data Scoring: Design and implement pipelines that utilize LLMs to analyze and score identity data in real-time. You will integrate AI models directly into the decision-making loop, balancing accuracy with latency and cost.
• Own the Data Architecture: Architect scalable data solutions using GCP and Python. You will manage data storage and retrieval using BigQuery and Apache Iceberg to support querying of TBs of data.
• Heavy Data Processing: Utilize Apache Spark for data transformations and batch processing when lightweight cloud functions are not enough.
• Manage High-Load Orchestration: Maintain and optimize our system instances. It involves complex dataflows, custom Python nodes, and performance tuning for 10k+ execs/minute.
• Release Lifecycle (CI/CD): Take ownership of the deployment process, ensuring that updates to pipelines and infrastructure are released safely with proper testing and rollback strategies.
• Database Optimization: Manage PostgreSQL performance under heavy load, optimizing complex queries and indexing strategies.
• Active AI Usage: Use Claude Code and other AI engineering tools to accelerate your own development, refactoring, and testing processes.
• Incident Resolution: Proactively monitor the system. When alerts fire, you investigate the root cause—whether it’s a database lock or an LLM hallucination—and fix it permanently.

Requirements

• 4-5+ years of experience in Data Engineering or Backend Engineering with a strong data focus.
• Production AI Integration: Experience integrating LLMs (OpenAI, Anthropic, Gemini) into production applications via API. You understand latency, token limits, and how to structure data for AI scoring.
• Expertise in GCP: Understanding of Google Cloud Platform (Cloud Functions, IAM, Networking).
• Strong Python: You write clean, efficient, and testable code. You are comfortable building custom logic where standard tools fall short.
• Big Data Stack: Experience with BigQuery, Apache Spark, and modern table formats like Apache Iceberg.
• Kubernetes (K8s): Experience deploying and scaling services in containerized environments.
• Workflow Automation: Understanding of workflow orchestration tools at a deep technical level. N8N is a big part of our domain, so familiarity with it is highly valuable.
• PostgreSQL Mastery: Proven ability to handle heavy write/read loads and optimize schemas.
• English: B2+ (Upper-Intermediate) or higher.

Culture & Mindset

• Self-improvement: You are a fast learner. You don't fear AI replacing you; you master it to replace your manual tasks.
• Ownership: You treat the Identity domain as your own business. If a scoring model drifts or a pipeline slows down, you notice it and fix it without being asked.
• Internal Locus of Control: You take responsibility for outcomes. If an external API fails, you build a fallback mechanism instead of just blaming the provider.
• Get It Done: You prioritize shipping value. You know when to use a simple script and when to build a complex architecture.
• Openness: You share knowledge freely. If you find a better way to prompt the AI for scoring, you share it with the team.

What We Offer

• Fully remote with flexible hours (aligned with EU timezones for syncs).
• AI-Native Environment: We provide licenses for Claude Code and encourage using the bleeding edge of AI tech for both daily coding and product features.
• High-Impact Role: You will directly influence how we identify and score users, impacting the core business logic.
• Cross-functional visibility: Work closely with Product and Tech Leads to shape the future of Identity.

• No Bureaucracy: Fast decisions, no legacy processes, focus on results.

If you thrive in high-ownership environments, move fast, and enjoy solving complex engineering problems with AI at the center, this role is for you. 

What We’re Looking For 

AI Engineering & Delivery (Products and with AI)

• Building AI into products: Hands-on experience integrating LLMs into real applications; experience with RAG, AI agents, copilots, or AI workflow orchestration.
• Building products with AI: You already use AI in your development workflow (LLM-assisted coding, prompt engineering, AI-based testing/code review, automation) and can point to examples where this has accelerated delivery. 

Architecture & Backend Engineering

• Strong backend engineering and architecture experience. We’re not tied to a specific language or framework. What matters is that you can architect robust, scalable backend systems and that you understand why certain decisions matter.
• Proven experience shipping production systems end-to-end. Not just designed it, not just prototyped it. You’ve been responsible for something real that runs in production and that clients depend on.
• Infrastructure and scalability awareness. 

Client-Facing & Communication

• Strong communication and client-facing skills, with the ability to present and explain complex solutions to both technical and non-technical stakeholders, including executives.
• Solid English proficiency suitable for executive-facing conversations. 

Ways of Working

• Ability to operate with high ownership and minimal handholding.
• Works effectively within a delivery team, including engineers, consultants, and BAs, rather than as a solo contributor. 

Nice to Have:

• Consulting or pre-sales experience (POC scoping, proposal shaping, estimation).
• Full-stack development background.
• Salesforce or CRM ecosystem exposure.
• Experience in real estate or financial services domains.

What You’ll Do 

Architect & Deliver AI-First Solutions

• Design and build production-grade AI-powered applications.
• Implement RAG pipelines, AI copilots, LLM integrations, and agentic workflows.
• Own architecture decisions across backend, infrastructure, scalability, and deployment.
• Lead technical delivery for client-facing AI initiatives. 

Use AI to Accelerate Engineering
We expect AI to be part of your development workflow. 

You should already be using:

• LLM-assisted coding;
• AI-powered development tools;
• Prompt engineering;
• AI-based testing and code review;
• Intelligent automation workflows. 

Support Pre-Sales & Client Conversations

• Join discovery and solutioning calls with prospects.
• Translate business problems into realistic technical solutions.
• Provide architecture direction and delivery estimates.
• Communicate clearly with both technical and non-technical stakeholders. 

Help Shape the AI Practice

• Define reusable AI architecture patterns.
• Improve AI delivery standards and engineering workflows.
• Influence tooling, implementation approaches, and best practices.
• Work directly with senior architects and leadership/C-level.
• Mentor engineers and team leads on AI delivery practices.
• Lead and operate small delivery teams under compressed timelines. 

Ascendix offers you:

Healthcare:

• 20 paid vacation
• 5 paid sickness

Career and professional growth:

• B2B and remote cooperation
• Career development and professional growth
• Technical performance reviews and 360 Evaluation

Job Description

Role Overview:
 

The Senior Full-Stack Developer position at Vertical Television involves acting as a technical pillar and the ultimate “go-to” person within the app development team. The role demands a highly independent professional with a strong frontend orientation, responsible for driving the architecture of a high-scale mobile app and operational web platforms. The developer will contribute to building the future of Vertical Television by combining cinematic storytelling with interactive, vertical-first technology, focusing on scalable application design and performance optimization.

Key Responsibilities:

• System & App Architecture: Architect, plan, and lead the development of the mobile app built with React Native and web platforms using React, ensuring a holistic and scalable system design.
• Vertical Video Feed & Playback: Own the core viewing experience featuring an infinite vertical video feed with instant time-to-first-frame, video preload/prefetch, player-instance recycling, and disciplined memory management across multiple concurrent video players.
• Technical Leadership & Mentorship: Serve as the technical expert and mentor for mid-level developers by providing guidance, conducting code reviews, and elevating engineering standards within the team.
• Standards & Reusability: adherence to coding standards, best practices, and promote a reusability-first mindset to maintain a clean, maintainable, and highly scalable codebase.
• Deep App Performance: Address complex performance challenges including app state management, native bridging, and video rendering optimizations such as player tuning, reducing frame drops, minimizing jank on scroll, and improving cold-start times.
• Monetization: Design and integrate in-app purchases, subscriptions, deep links, attribution, and user-behavior tracking end-to-end, including client SDK implementation and server-side receipt validation.
• Cross-Functional Collaboration: Work closely with Product, Design, and Backend engineering teams to deliver fast iterations of complex features in a dynamic startup environment.

Additional Expertise and Advantages:

• Experience with mobile CI/CD and release operations one of EAS, Fastlane, store submission, OTA updates (CodePush, EAS Update), and end-to-end testing.
• Background in high-growth startups or mobile entertainment products, with familiarity in vertical/short-form feed products similar to TikTok, Reels, or Shorts.
• Understanding of ad-tech and SSAI (AdMob, Google IMA) and subscription monetization modeling.
• Knowledge of DRM technologies (Widevine, FairPlay), offline downloads, and transcoding pipelines (Mux, AWS MediaConvert, AWS IVS) as beneficial skills.

Ideal Candidate Profile includes experience in the following areas: 

Streaming & vertical feed (the differentiator):
