[Hiring] Senior Backend Engineer @Modash

Role Description

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.

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.

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.
• 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.

What you'll actually own

• Keep creator data flowing at massive scale.
• Make collection resilient when the outside world isn't.
• Improve the economics of collection.
• Own production, not just the code.

What the day-to-day looks like

Here’s what a typical week might include:

• Monday: Trace failure patterns and design a resilient fix.
• Tuesday: Redesign part of the subscription system balancing customer value against cost.
• Wednesday: Pair with a Data Search engineer to improve freshness.
• Thursday: Review a new request-routing approach and model throughput.
• Friday: Improve data-quality checks based on observability reviews.

We keep meetings purposeful and protect time for deep work.

Qualifications

• Built large-scale backend or data systems.
• Shipped systems from concept to production.
• Designed distributed systems.
• Built resilient integrations.
• Worked with proxy management or request routing.
• Taken operational ownership.
• Worked autonomously on ambiguous problems.
• Communicated clearly across teams.

Bonus Points

• Experience with social-media APIs.
• Knowledge of data-quality frameworks.
• Experience with large-scale collection systems.
• Curiosity about the creator economy.

Our stack

• AWS, with Pulumi for infrastructure as code.
• TypeScript and Node.js as the primary languages.
• Aurora Limitless/Postgres for subscription and collection state.
• S3 for raw data-lake storage.
• CloudWatch for observability and alerting.
• Proxy networks and custom routing layers.
• ECS, SQS, Athena, and other AWS services.
• Slack, GitHub, Linear, Notion, and Cursor.

Compensation and Benefits

• Annual salary range is 80,000€ - 110,000€.
• Flexible hours.
• Unlimited paid vacation.
• Personal development support.
• Real ownership of production-critical infrastructure.
• Regular offsites for team connection.
