Remote — Data Core Team — Full-time Hey, I'm Andrei . I’m hiring a Senior Backend Engineer to join the Data Core team at Modash. Modash helps brands find, understand, and work with creators across Instagram, TikTok, and YouTube. More than 2,700 companies—including Stanley 1913, Sennheiser, and NordVPN—use us to manage and scale their creator partnerships. Every one of those products depends on fresh, reliable creator data. Data Core owns the systems that collect and maintain profiles for 400M+ creators across social platforms, process billions of data points, and keep the rest of Modash supplied with the raw material it needs. That’s where you come in. Why we're hiring Data Core isn't an internal support team. It owns the collection infrastructure that the entire Modash product—and every downstream data team—depends on. Collecting social data at this scale is a hard distributed-systems problem. APIs change without warning. Providers become unreliable. Platforms rate-limit requests. Data grows stale. A tiny inefficiency becomes expensive when repeated hundreds of millions of times. We need a senior engineer who can design resilient services, make thoughtful tradeoffs between coverage, freshness, reliability, and cost, and take production-critical systems from a rough idea to dependable operation. You’ll join the specialised Data Core team and work closely with Data Search, Data Insights, product teams, and company leadership. You’ll have real ownership, but you won’t work in isolation. If you want a feel for how we think about building software, check our Engineering Blog . What you'll actually own 1. Keep creator data flowing at massive scale. You’ll build and evolve the systems that collect and maintain 400M+ creator profiles across Instagram, TikTok, and YouTube—keeping billions of data points fresh enough for search, analytics, APIs, and customer-facing products. 2. Make collection resilient when the outside world isn't. You’ll design services that handle third-…

Hey, I'm Adrian . I’m hiring a Senior Software Engineer to join the Data Search team at Modash. Modash helps brands find, understand, and work with creators across Instagram, TikTok, and YouTube. More than 2,700 companies—including Stanley 1913, Sennheiser, and NordVPN—use us to manage and scale their creator partnerships. Behind that product is a fascinating search problem: helping customers find the right people across 400M+ creator profiles and billions of media files. We’re combining large-scale data processing, traditional retrieval, vector search, multimodal embeddings, and LLMs to make that possible. That’s where you come in. Why we're hiring Search at Modash isn't an internal platform or a support function. It is one of the core products customers use to discover creators. The scale is large, the data is messy, and the search intent is often complex. A customer might be looking for creators in a specific niche, people whose content conveys a certain visual style, or accounts that resemble a group they already know. Solving that well requires more than adding another filter or calling an LLM API. We need a senior engineer who can work across the full retrieval system—from data and indexing pipelines to embeddings, ranking, relevance, and low-latency serving—and take ambiguous product problems all the way to production. You’ll join the specialised Data Search team and work closely with Data Core, Data Insights, product teams, customers, and company leadership. You’ll have real autonomy, but you won’t work in isolation. If you want a feel for how we think about building software, check our Engineering Blog . What you'll actually own 1. Make creator search meaningfully better. You’ll improve how customers discover creators across 400M+ profiles and billions of media files. That includes retrieval, filtering, ranking, relevance, speed, and the product decisions that connect them. 2. Turn multimodal data into searchable intelligence. You’ll build systems that gen…
