About us

GigRadar is the market leader in our vertical: AI-powered lead generation on Upwork for agencies and freelancers. We remove the need for in-house bidding teams and multiply agencies' marketing efficiency.
 

A quick picture of who you'd be joining:

• Infrastructure trusted by 3,000+ Upwork agencies worldwide.
• 4.7/5 "Excellent" on Trustpilot, with 91% five-star reviews.
• 30K+ LinkedIn audience and a strong founder brand.
• Backed by a leading SalesTech/MarTech player (on our board)
• A product line of AI agents: Sardor AI (auto-bidder — finds relevant jobs, writes personalized cover letters, and submits within 15 minutes), Laziza AI (AI SDR — runs conversations, handles objections, books meetings), Upwork CRM, Upwork Analytics, and GigRadar Inbound.

We're not a day-one startup, and we're not a slow enterprise. We have a proven business model, a mature product, a fast-growing AI lineup, and clear leadership in our niche - confident operators growing fast.

And most importantly for this role: strong channels are already running.

• SEO — a dialed-in channel built entirely on AI agents.
• Email + LinkedIn outreach — its own team.
• Partner / referral network — its own team.

You're not here to patch holes but you're here to build a new amplifier vertical on top of a working machine. You won't have to prove the business works; it's been alive for years. You'll get to build your own growth engine and scale it. On top of that, we have a large library of ready material (case studies with numbers, Upwork Reports, community content, reviews) you can turn into powerful marketing.

The mission

Build and launch a new inbound-demand vertical that consistently generates 200–300 booked demos per month through organic content, an authoritative newsletter, and automated funnels from free products and automate it with AI, not manual labor or a bloated team.

You are a one-person orchestra.
Strategy, hypotheses, copy, landing pages, sequences, content, analytics — you run it yourself, using AI as your "extra hands" (design, copy, front-end, and research through AI tools, not contractors).

What you'll do

Lifecycle / CRM marketing (core)

• Build and monetize segmented work across the base: newsletter, unsubscribers and cooled-off leads, leads from the sales pipeline, leads from cold outreach. Different segments → different scoring → different sequences.
• Find the signals yourself and turn them into triggered sequences. Example signals: booked a demo but didn't show; read N newsletter issues; used a free product X times; sat in the pipeline for N days. These are examples — your job is to spot such signals and build flows around them.
• Reactivate the "sleeping" base (several thousand leads no longer worth active outreach but recoverable through sequences).

Newsletter as an asset

• Build a genuinely strong, authoritative newsletter — #1 in our space on building and scaling a business / lead gen on Upwork for service companies and freelancers. Not a "mailing list," but a media asset that grows the base and warms it toward demos.

Growth / organic

• Organic growth on LinkedIn and X (Twitter), plus experiments (Reddit, niche content, etc.): viral/value posts that feed funnels.
• Scale a network of established employee accounts (founder-led + team advocates) — not faceless farms, but real personal brands at varying stages that need to be systematized and amplified.
• Funnels from free products: lead magnet → email capture → nurture → auto-purchase of a paid product or a demo.

AI as the way you build it all "by hand"

• Build repeatable marketing systems on AI tools (Cowork, Codex, and similar): a content engine (agents pull data → assemble a content plan → turn it into posts), sequence generation, landing pages, calculators, banners — without pulling in developers or design studios.
• Mine our large internal content library into posts, funnels, and sequences — rather than inventing from scratch.

CRO / web / reputation

• Raise conversion on the site and landing pages (demo page, free-product pages).
• Work on brand reputation: systematic review responses (Trustpilot / G2, etc.), messaging, demo experience.

What we're looking for

We are looking for a marketer who applies AI brilliantly to marketing problems, not a developer placed on marketing.

• 3–5+ years in marketing, specifically in B2B SaaS for the US market.
• A strong foundation in conversion marketing: you crank conversion through meaning — audience pains and desires, purchase triggers, offer structure. That's your base, not just "having seen a lot."
• Proven cases with numbers: you personally wrote converting copy in newsletters/sequences and personally moved landing-page conversion — and can show "before → after."
• Proven volume: you've generated a comparable number of SQLs/demos (in the hundreds per month), not just "ran campaigns."
• Hands-on AI fluency: you already build marketing systems with AI (Cowork / Codex / etc.) and can validate what AI produces, not just publish it blindly.
• Fluent English.
• Ideal background: B2B SaaS in a close space including SalesTech, MarTech, GTM-tech that sold to agencies and service companies. Then you already know our buyer and need no ramp-up on the ICP. Candidates from an agency background aren't a fit; we need a product/SaaS background
• A hard requirement — everything hands-on. The "I assigned tasks to a team/contractors and they did it" profile isn't a fit. We need someone who did it themselves and owned the result.

Our stack

• HubSpot — the core: email, triggers, client documentation.
• AI-first analytics: our agents traverse HubSpot data and return analytics.
• Intercom — behavioral triggers and analytics for active clients.
• Pre-purchase leads — all in HubSpot.

Success metrics (KPIs)

• North star: booked demos per month — ramp to 200–300/month within 3–6 months.
• Newsletter: base growth + end-to-end conversion of the warmed segment to demos (target ~2–3%).
• Demo-page CRO: from a baseline ~2–4% to 6–8%+.
• Free → paid: toward the PLG median of ~9%+.
• Reactivation of the sleeping base: % of leads brought back.

Compensation

• Base: $2,500–3,500/month (depending on level).
• Performance bonus: $1,500–2,500/month at 100% of plan, tied to demos, SQLs, and pipeline contribution; quarterly accelerator for overperformance.
• OTE at 100% of plan: ~$4,000–6,000/month.
• Remote working
• Carrer path to CMO.

What to bring to the call with our team

• Cases with numbers — where you drove growth and which metrics you actually moved (not "the team did it"), including the volume of SQLs/demos generated.
• A live screen-share — show your AI layer (Cowork / Codex / etc.): what you build by hand as a marketer.
• Conversion-marketer thinking — how you crank conversion through audience pains/desires/triggers.

ABOUT THE WORK

Riffbird is one of the largest social recruiting agencies in DACH, with 600 clients across Austria, Germany, and Switzerland. We run paid social campaigns, pre-qualify applicants on the phone, and operate the full hiring funnel for our clients.

The service works. The infrastructure does not. Today it runs on a patchwork of external SaaS tools held together by manual operator work. We're now bringing the operational layer in-house, piece by piece, and we're building it so LLM agents can do most of the work that humans currently do by clicking around.

You're coming in to build that layer. It's not a greenfield reinvention of recruiting software. It's the platform that turns an already-working service into something agents can run.

———————————————————————

WHAT YOU'LL BUILD

One platform, built around a single asset and a set of agents that operate on it.

THE DATA LAYER (the most important thing we own)

A unified candidate and client database. Every campaign, every screening call, every interview outcome feeds it. A candidate who doesn't fit Client A stays discoverable for Client B with proper consent. Full-text plus semantic search. This is the part of the business that's hardest to replicate from outside, and everything else on the platform exists to feed it, query it, or act on it.

THE AGENT WORKFORCE

The operational work we do today, moved one capability at a time onto agents that can run with human supervision:

• Ad creative generation (already live with Claude Code, gets expanded and integrated)

• Recruiting landing page generation, per client and per role

• Candidate research, active sourcing, and headhunting (LinkedIn, niche platforms, our own pool)

• Outbound qualification calls (telephony integration, region-by-region pitch and screening logic, full transcript and outcome tracking)

• Outreach and follow-up drafting

• Pipeline operations: moving candidates through stages, flagging stalled ones

• Reporting and anomaly detection across ad spend, funnel, and conversion

Our operators stay in charge of the work, the agents scale what they do. A capability moves from human-driven to agent-driven only when the evals back it up.

THE CLIENT WORKSPACE

Where our 600+ clients see their pipelines, get their reports, and talk to us. Multi-tenant, fast, clean. Today this is split across a stack of external tools and Slack, getting it in-house is step one.

THE AGENT PLATFORM

Typed, scoped tools, audit trails, eval pipelines, the infrastructure that lets us ship new agent capabilities without breaking client work. GDPR-clean throughout (German clients, German applicants, non-negotiable).

 

———————————————————————

WHAT YOU BRING

We don't care which language or framework you pick. We care that you've done the hard parts somewhere before:

• 5+ years shipping production systems where state, queues, webhooks, and idempotency actually mattered, not just CRUD over a single table

• Built and operated multi-tenant SaaS with a real permission model, not just WHERE tenant_id = ? stitched into every query

• Shipped LLM features in production where it had to work: RAG that retrieved the right thing, tool-calling that didn't hallucinate the schema, evals that caught regressions before users did

• Designed APIs and data models that agents can use without supervision, or at least understand what changes when the consumer is an LLM instead of a frontend

• Operate well in EU/GDPR territory, or have the discipline to learn it without us getting fined (in cooperation with our GDPR-expert)

• Async-remote operator: you write things down, you disagree in writing, you don't need standups

• Comfortable working directly with a founder who builds product himself with AI tools but isn't going to sparring-partner you on systems design. You own the engineering decisions, no PM in the middle. 

———————————————————————

WHO YOU ARE

You're already living in this stuff. You read what comes out of Anthropic and OpenAI in real time, you've shipped with the APIs, you have opinions about which eval frameworks actually work and which are theater. This is the role you've been waiting for, not the role you applied to because the comp was good.

You move fast, but you've been burned enough times to know when fast is reckless. You can hold that trade-off.

You want your name on something real, not be engineer number 47 on someone else's feature team.

———————————————————————

NICE-TO-HAVE

• Recruiting, HR-tech, or staffing-software experience

• Hired and led small engineering teams before

• Voice, telephony, or RTC experience

• Strong opinions about agent UX (what a tool should and shouldn't expose to an LLM)

———————————————————————

WHAT YOU GET

• Greenfield, full ownership. You pick the architecture, you pick the tools. No legacy code, no committee, no permission slip.

• A founder who ships. Bernd (founder) uses Claude Code daily and builds production tooling himself. You get a counterpart who understands what you're doing, not someone managing you from outside.

• Above-market pay. We won't quote a band on the public posting, but we definitely pay properly for this role.

• The opportunity to take full responsibility of the system architecture short-term and build a team to support you long-term.

• Tooling and hardware budget that respects your craft. Premium AI subscriptions, top-spec machine, conference and training budget, trips to the Bay Area when there's a reason.

• Optional two retreats a year. Austria and Dubai. Proper time together with the founder and core team, not Zoom.

———————————————————————

HIRING PROCESS

1. 30-min intro call with Bernd (founder)

2. 60-min architecture conversation, no leetcode, never

3. Paid pair-programming or take-home on a real Riffbird problem (4 to 8h, paid at market rate)

4. References, decision, offer within 7 days

We're a 20-person team building a browser-native scientific data platform used by Novartis, J&J, Daiichi-Sankyo, and other top pharma and biotech companies. Our platform was already 10x faster than the competition and delivered more value for less — even before the AI era. Now, we're taking it to the next level.

We're competing with Spotfire, Certara, Dotmatics, and Schrödinger — and winning. How? By building faster and smarter. Our engineering team has fully embraced AI-driven development (Claude Code, agentic workflows, AI-assisted testing), and it's become our biggest force multiplier. We ship in weeks what used to take quarters.

We're looking for an engineering leader who's already living this way — someone who has hands-on experience with agentic development tools and can help lead a team that's pushing the boundaries of what a small, focused group can deliver. You'll report directly to the CEO and have real authority to shape how we build.

What you'll build and lead

This isn't a "manage meetings and write status reports" role. You'll own critical product areas and ship alongside the team. Here's what's on the roadmap:

• AI-powered agentic workflows — Autonomous scientific agents that utilize Datagrok's plugins and integrations as tools.
• Automated testing at scale — Automatic scenarios using Playwright + AI, AI-driven bug reproduction and fixing, stress tests, unit tests, system health tests, plugin tests - everything integrated into CI-CD and managed by AI
• Platform evolution — Cross-application integration and eventing mechanicm, ClickHouse as an analytical backbone, high-performance computations
• Enterprise integrations — Databricks connectivity (ADBC/Arrow for 2–10x speedups), HuggingFace model integration, and dashboard importers for Tableau and Spotfire migrations
• DevOps and infrastructure — ArgoCD deployments, Docker image management, containerized dev environments, and OpenTelemetry observability across a multi-layer stack
• AI-powered knowledge graph — mapping source code, features, tests, docs, and Jira tickets to enable impact analysis and agentic development workflows across the entire codebase
• Process improvements - code reviews, better planning/outcome system, DX improvements, onboarding for new developers

What we're looking for

Must have:

• You've already adopted autonomous agentic development in your own workflow (harnesses, tool-use architectures, AI-driven testing, etc)
• 5+ years as a strong engineer who still codes. This is a hands-on position
• Experience leading a team (formal title matters less than demonstrated leadership)
• Proficiency in TypeScript or Dart; comfort picking up new languages fast. Our core stack is Dart and TypeScript, with C++/WASM, Python, R, Julia, and Matlab in scientific plugins
• Track record of delivering complex software products — not just managing people who do
• You see a problem, you fix it. You don't write a proposal about fixing it. You don't wait for permission
• Strong communication skills and fluent English — you'll work directly with technical clients at pharma companies and present to enterprise IT teams

Strong pluses:

• Life sciences, cheminformatics, or bioinformatics background (or genuine curiosity about this space)
• Experience building agentic AI systems — not just prompting LLMs, but designing autonomous pipelines, harnesses, tool-use architectures, or AI-driven testing frameworks
• Background in high-performance computing, data visualization, or scientific computing
• Startup DNA — you've built things from zero, worn multiple hats, and thrive without a playbook

What we offer

• Real ownership — reporting directly to the CEO, you'll lead critical product areas for a platform deployed at top-10 pharma companies, not maintain someone else's legacy code
• An AI-first engineering culture — we're not "exploring AI adoption." We've already made the transition. You'll help take it further
• Direct client impact — your work will be used daily by scientists doing drug discovery at companies you've heard of
• Startup speed, enterprise clients — the autonomy and pace of a small team, with the validation of Fortune 500 deployments
• Fully remote, zero bureaucracy, flexible hours, unlimited PTO
• Competitive compensation with growth equity opportunity
• Paid training and certifications

We’re looking for an experienced backend developer to play a key role in building and evolving the server-side of our product. You’ll be working on a high-load, real-time system where performance, scalability, and clean architecture matter. This is not about maintaining legacy code — it’s about designing, improving, and refining a complex backend that serves a live product with real users.

🧩 Must-have skills:

• 🧠 Strong knowledge of modern C++ (C++17 / C++20 / C++23)
• 🗄 Hands-on work with Redis, MySQL, and PostgreSQL
• 📄 Experience with Swagger / OpenAPI specifications
• 📨 Knowledge of RabbitMQ or similar message brokers
• 🌐 Strong understanding of REST API and WebSocket communication
• ⚙️ Experience with parallelization and multithreaded systems
• 🏗 Solid OOP fundamentals and practical use of design patterns
• 🔍 Ability to easily understand existing codebases and confidently refactor them with better solutions
   

✅ Nice to have:

• 🐍 Experience with Python
• 🛠 Experience with Pistache for building REST services
• 🖥 Familiarity with Qt / QML
• 🔁 Basic understanding of CI/CD pipelines
• 💻 Bash scripting skills
• 🐳 Experience working with Docker
   

🧠 About the company and product:

• We’re a product-driven company in the gambling niche
• Developing our own licensed online poker room
• Working in two-week Scrum sprints
• Every feature includes:
  — a detailed specification
  — a Figma design
• CI/CD is fully automated and stable
• The team is carefully selected — strong professionals, great collaboration, respectful environment
   

🚀 What we offer:

• A live product with real users in production
• Fast iterations, clear processes, open communication
• Respect for your time and expertise

Influence Pro Services — продуктова компанія з власною технологічною інфраструктурою та командами розробки. Зараз ми запускаємо новий напрям: портфель B2C consumer-продуктів на ринки Tier 1 у нішах health & wellness, money & career, lifestyle і productivity.

Це роль із фокусом на побудову продуктів з нуля: від валідації гіпотези до MVP, пошуку product-market fit і подальшого масштабування. Портфель великий, тому ми будуємо кілька паралельних продуктових команд — і шукаємо продактів, які зможуть стати ядром цих команд.

Що ти будеш робити

• Валідувати продуктові гіпотези з нуля: аналіз конкурентів, landing-тести, pre-MVP експерименти 

• Формувати product vision і roadmap для свого кластеру продуктів, балансуючи між швидкими валідаціями та стратегічними ставками

• Запускати продукти end-to-end: від discovery і написання PRD до GTM, перших платних користувачів і пошуку product-market fit

• Зводити юніт-економіку на етапі pre-launch і трекати її після: LTV, CAC, payback, retention, ARPU, MRR/ARR — на рівні впливу на P&L продукту

• Будувати систему product discovery: дослідження, A/B-тести, аналітика, конкурентний моніторинг — як регулярний процес, а не разовий захід

• Працювати з підписочною монетизацією: paywall-структури, intro-офери, цінові тести, плани

• Брати участь у формуванні команди під продуктовий юніт та керувати нею

• Аналізувати ринок, конкурентів і тренди — шукати точки росту і нові ніші всередині свого напряму

Що ми очікуємо

• 4+ роки в продакт-менеджменті, з кейсами запуску або масштабування продуктів

• Досвід роботи з B2C продуктами з підписочною моделлю (mobile та web) на ринках Tier 1 

• Глибоке розуміння юніт-економіки: LTV, CAC, payback, retention, ARPU — на рівні самостійного зведення моделі та захисту її перед стейкхолдерами

• Підтверджений досвід запуску продуктів з 0 до 1 або ведення продукту на ранній стадії (pre-PMF / пошук PMF)

• Робота з аналітичними інструментами: Amplitude / Mixpanel або аналог

• Вміння писати чіткі PRD, one-pager-и та roadmap-и і захищати їх перед C-level

• Розуміння принципів UI/UX і вміння впливати на дизайн-рішення

• Розуміння того, як працює маркетинг performance-продуктів: UA, ASO, paywall-оптимізація — на рівні взаємодії з командою

• Досвід роботи з AI-powered продуктами

• Англійська Upper-Intermediate і вище

• Ownership-mindset: бачиш проблему — ініціюєш рішення, а не чекаєш інструкцій

Буде плюсом

• Досвід у 0-to-1 стартап-середовищі або запуску продуктів з нуля всередині компанії

• Досвід монетизації: paywall-тести, цінові експерименти, intro-офери, структура планів

• Бекграунд у performance-маркетингу або product marketing

Що ми пропонуємо

• Реальний ownership та прямий вплив на продуктові та бізнес-метрики — і прозорий зв'язок між твоїми рішеннями і P&L продукту

• Бюджет на дослідження, А/Б-тести і MVP-валідації

• Remote-first культура з гнучким графіком
• 24 дні оплачуваної відпустки та лікарняних
• Робота в середовищі сильних фахівців, сфокусованих на продуктових інноваціях і реальному впливі
