Senior Backend Developer (Torch Team)

Semrush is a brand visibility platform, empowering marketers to command their online presence and create measurable impact. We unify SEO authority and AI visibility, so brands are found, cited, and chosen everywhere search happens. That’s how Semrush gained the trust of over 28 million users—from scaling startups to Fortune 500 companies.

Here, you own the way you work, but we move as one unbeatable team.

We don’t just lead the market, we’re busy creating the world where Semrush is an unfair advantage for every marketer.

We move fast in ways to help you grow. Here, you have room to experiment, keep what works, and learn quickly from what doesn’t.

Ready to share our ambition and make an impact? Then, this role may be for you.

• Build high-quality, scalable, maintainable Python services and data pipelines.
• Collaborate with Data Scientists to build cutting-edge ML/AI systems.
• Design and operate cost-effective data pipelines over PostgreSQL, BigQuery, ClickHouse, and GCS — including schema migrations (Alembic) and data quality checks.
• Integrate and optimize LLM workloads end-to-end: multi-provider routing, cost monitoring, fallbacks, and continuous evaluation.
• Orchestrate workflows with Temporal and deploy on Kubernetes/GCP (Docker, Pub/Sub, KMS, IAM).
• Own reliability and observability — Grafana, Prometheus, Sentry, Langfuse — and keep pipelines healthy at scale.
• Maintain CI/CD pipelines for automated, safe deployments (including DB migrations).
• Drive code quality through clean code, testing, pair programming, code reviews, and knowledge sharing.

Move together. Raise the bar. Learn fast—grow faster. That’s the default. And here’s what else is needed to succeed in this role: 

• 5+ years of strong software engineering fundamentals — clean code and solid testing practices.
• Strong Python development skills.
• Experience with Docker; Kubernetes is a plus.
• Comfortable with CI/CD pipelines and deployment/infrastructure management.
• Data engineering experience — building scalable, cost-effective pipelines — is highly valued.
• Excited to work in a fast-paced environment and collaborate with Data Scientists to build innovative ML/AI systems.
• Solid knowledge of SQL with maintaining relational databases is a plus.
• Motivated to grow both personally and professionally.

Torch team is an engineering team building LLM-powered products for Content and brand intelligence. We own two domains:

• AIO (Brand presence, serenity, prompt tracking) — measuring and improving how brands show up across AI/LLM answers (ChatGPT, Gemini, Perplexity, Google AI Overview). Think "SEO analytics for the AI-search era," without relying on classic Google rankings.
• Content — AI-driven content scoring, SEO/GEO guidelines, and content-generation suggestions.

We run large-scale data pipelines that turn raw LLM/SERP responses into trustworthy brand-visibility metrics. Cost-efficiency at scale is a core engineering challenge — we continuously benchmark and switch between LLM providers (OpenAI, Gemini, Mistral, Grok, Nebius, Claude) to balance quality and spend.

• Unlimited PTO
• Hobby & team building budget allowance
• Employee Support Program
