About the role

We're looking for an SEO Junior Specialist to support one of our senior SEO team members with day-to-day operational tasks. You don't need to be an expert — we'll teach you everything. What matters most is attention to detail, responsibility, and a genuine interest in SEO.

What you'll do:

• Implement meta tags and conduct basic on-page audits
• Monitor Google Search Console and flag technical issues
• Assist with keyword research and content brief preparation
• Compile link-building prospect lists and assist with backlink audits
• Collect performance data from GA, GSC, and rank trackers
• Maintain task logs and project documentation in ClickUp / Notion

What we're looking for:

• Basic understanding of how SEO works
• Attention to detail and ability to follow instructions accurately
• Comfortable with Google Docs / Sheets
• Written English B2–C1
• Proactive communication — especially when blocked

Nice to have:

• Any experience with Ahrefs, Semrush, or Ubersuggest
• Completed SEO course (Google Digital Garage, Semrush Academy, etc.)
• Familiarity with WordPress or any CMS

What we offer:

• Mentorship from an experienced SEO Specialist from day one

• Fully remote, async-friendly work
• Transparent team culture, no micromanagement

Our client is an AdTech SaaS built on Shopify that helps e-commerce businesses run ads on Meta and Google. The product is evolving from a simple setup tool into a full AI-driven solution: it analyzes a store, identifies the best product opportunities, generates creatives, launches campaigns, and optimizes them automatically. The merchant sets a target ROAS — the system handles the rest.

They are looking for a Senior Engineer who can take real ownership of the product and help deliver the next stage of growth.

What you’ll own

In the first months, you’ll dive deep into the existing platform: stabilizing, maintaining, and building context. Then you’ll move into:

• AI-native experience: building store intelligence that analyzes merchant data, scores products by predicted ROAS, and drives campaign decisions automatically
• Deep Shopify integration: ensuring the product lives where merchants already work (Shopify admin, Sidekick, Flow), not as a separate tool
• Platform reliability & UX improvements: improving onboarding, ROAS optimization, and performance transparency

• Quality at every stage: owning QA as part of delivery — writing specs with acceptance criteria, critically reviewing AI-generated code, and ensuring features are tested before release

   

How the team works

The team follows an AI-assisted development approach:
spec → generate → review → refine → ship

You don’t need to write every line manually — but you do need to:

• write clear specs
• review code confidently
• maintain a high quality bar

You’ll work directly with the founders — no PM layer, no excessive processes.

This role is for you if:

• You have 5+ years of production experience with Python and React
• You have hands-on experience with AWS (EC2, RDS, S3, Lambda or similar)
• You’re comfortable owning the full stack (frontend, backend, infrastructure)
• You’ve worked with Shopify API, Meta Marketing API, or Google Ads API
• You’re used to being the primary engineer and making architectural decisions
• You can balance support and feature development
• You’ve used AI coding tools (Cursor, Claude Code, Copilot) and understand their strengths and limitations

• You treat QA as part of shipping (tests, code reviews, validation before release)

   

Nice to have

• Experience building or maintaining Shopify apps
• Familiarity with LLM APIs (OpenAI, Gemini)
• Background in AdTech or performance marketing

What our client offers

• Real equity — joining as a key engineer at a pivotal stage
• Ownership over architecture and decisions
• Fully remote, flexible schedule
• Competitive salary
• Paid vacation

Role Purpose

Support the full engineering cycle across research, development, and product improvement. The role bridges technical expertise, requirements analysis, and component-level work to deliver efficient, reliable, and competitive solutions.

Responsibilities

Component Selection

• Select components based on required technical parameters and mission constraints

Firmware Development & Adaptation

• Build firmware from source for specific camera chipsets; disable unused modules to reduce load and improve boot time
• Configure H.264/H.265 video encoder parameters for optimal balance of image quality, bitrate (radio/fiber transmission), and minimal latency — critical for FPV applications

Intempt.com is an agentic growth platform — CDP, CRM, experimentation, personalization, recommendations, journeys, analytics, and AI agents in one platform. One event-centric data model powers everything. Small team, high output. You own systems, not tickets.

What you'll build

Event pipeline. Kafka ingestion → Flink processing → validated, deduplicated, identity-stitched events available to every downstream system in near real-time. Millions of events/day.

Identity resolution. Anonymous-to-known merging, cross-device stitching, account grouping, attribute reconciliation. The backbone of our CDP — if profiles are wrong, everything downstream is wrong.

Data layer across four engines. Postgres (profiles, accounts, consent, config). Redis (session state, real-time segments, feature flags). Neo4j (account hierarchies, affinity graphs). ClickHouse (funnels, retention, experiment results, dashboards).

LLM infrastructure. Our AI agents (Qualification, Lifecycle, Research, + orchestrator Blu) hit inference APIs at scale. You build the machinery — prompt routing, model selection, token budgets, response caching, failover — not the prompts.

Public APIs. Track, identify, consent, choose, recommendations feed. You own correctness, performance, and evolution.

Typical week

• Ship a Flink job computing real-time experiment metrics → ClickHouse
• Debug a profile merge edge case where alias() fired after events were already attributed
• Take a ClickHouse retention query from 8s to 200ms
• Wire a new Shopify/HubSpot attribute path into unified profiles

• Instrument an LLM call path with token tracking, latency monitoring, automatic fallback

   

What you need

• Java — deep, production-level. JVM tuning, GC behavior, concurrency, data structure choices at 50k events/sec.
• Postgres — migrations, indexing, connection pooling, replication. Not just SELECT.
• Redis — beyond caching. Pub/sub, sorted sets.
• Kafka — topic design, consumer groups, backpressure, exactly-once semantics.
• Flink (strong plus) — stateful processing, windowing, checkpointing. Spark Streaming / Kafka Streams also counts.
• ClickHouse or Neo4j — working knowledge of at least one. Ideally both.

• LLM integration — inference APIs in production. Token limits, latency, retries, cost control.

   

Who you are

• 3–5 years building backend systems. Mid-level operating like senior.
• You own problems end-to-end: root cause → fix → deploy → monitor.
• You learn fast. You'll hit unfamiliar systems. Read docs, build mental model, ship.

• You write code others can maintain and communicate in writing — design docs, PR descriptions, postmortems.

   

What we offer

• Work alongside some of the best backend and full-stack engineers you'll ever meet
• Work directly with the founder — a UC Berkeley computer scientist who's in the code daily
• Autonomy — context, not micromanagement
• A codebase young enough to be shaped by you

Language Requirements

• At least an intermediate level of spoken and written English, enabling clear and effective communication with team members and stakeholders.

   

Hiring Process

1. 15-minute Founder Interview

2. 45–minute Engineering Interview

    

   • Architecture reasoning
   • Code/system walkthroughs
   • Scaling and failure-mode thinking

How to apply

Please email hey at intempt.com  Subject: "Backend Platform Engineer" Resume + one or two things you've built that you're proud of. No template. Just what's real.
