Workload: full-time, remote
Start: asap
Duration: long-term
Location: any
English: B2

Technical requirements (general)
- 3+ years of production blockchain experience in BTC. Multi-protocol experience (strongly preferred).
- Java + Spring Boot + SQL
- Familiarity with test-driven development (TDD) and/or behaviour-driven development (BDD) as working practices, writing tests before or alongside implementation.
- Familiarity with Domain-Driven Design principles.
- Comfortable working in a monorepo structure with shared libraries, cross-squad code visibility, and coordinated CI/CD pipelines.
- Proactive communication, raising blockers, design concerns, and cross-squad dependencies.
- Written and verbal communication in English must be at a professional level.

Technical requirements (specific)
- Deep Bitcoin protocol expertise: PSBT format (BIP-174 and subsequent updates), UTXO management and coin selection algorithms, SegWit transaction structures, script types and descriptor formats (Taproot out of scope).
- Multi-signature coordination: BIP-48 (multi-sig derivation paths), BIP-67 (lexicographic key sorting), P2WSH script construction, PSBT combination and finalisation workflows.
- Fee estimation: Mempool analysis, RBF (Replace-By-Fee) and CPFP (Child-Pays-For-Parent) fee bumping strategies, fee rate prediction.
- Transaction construction: Witness data assembly, BIP-143 (SegWit sighash), DER signature encoding, low-S enforcement. Familiarity with sighash types. SIGHASH_ALL is the production default for custody; engineers should understand the full sighash taxonomy for validation and edge-case handling but implementation focuses on SIGHASH_ALL.
- Transaction lifecycle and remediation: Stuck transaction detection via mempool monitoring, RBF and CPFP execution for fee bumping, handling transactions that remain unconfirmed for extended periods, and managing the operational decision of when to replace vs wait.
- UTXO indexing and balance management: Experience with UTXO set tracking, balance computation from unspent outputs, UTXO consolidation strategies during low-fee windows, and address-level balance monitoring for deposit detection.
- Address management: Gap limit handling for HD wallets, change address allocation from internal derivation branch (m/84'/0'/0'/1/*), address reuse prevention, and descriptor-based address discovery for wallet import and recovery scenarios.
- Chain semantics and failure modes: Understanding of Bitcoin's probabilistic finality (confirmation depth vs settlement assurance), dust output limits and their implications for UTXO management, fee spike behaviour during congestion events (e.g. ordinals, inscription surges filling blocks for extended periods), double-spend detection for unconfirmed transactions, and the operational difference between a transaction that is "broadcast" vs "in mempool" vs "confirmed at depth N." Engineers must understand that Bitcoin has no concept of a "failed" transaction that consumes fees; a transaction either confirms or it doesn't, and unconfirmed transactions can be replaced or may eventually confirm unexpectedly.
- Production experience: Operating Bitcoin custody or wallet infrastructure at institutional scale, not testnet-only or personal wallet experience.

Candidate's responsibilities
Bitcoin wallet management, UTXO handling, transaction construction (PSBT, SegWit), multi-signature coordination, fee estimation.

We are looking for a Lead Data Engineer to join our team and contribute to one of Europe's leading online automotive marketplaces, serving 30+ million monthly users across 18 countries.

As a Lead Data Engineer, you will lead a team of data engineers and analysts, partnering closely with business stakeholders and senior analysts to translate marketplace analytics needs — from web & app tracking to marketing performance — into robust data models and pipelines that power the company's key business decisions.

This role sits closer to the business than a typical data engineering position. The Data Platform Engineering team owns the underlying platform and infrastructure, so you'll focus on understanding analytics use cases, shaping data models, and enabling analysts and stakeholders to answer their most important business questions.

Responsibilities:

• Lead and mentor a team of data engineers, providing technical direction as well as people leadership.
• Partner with business stakeholders and senior analysts to gather requirements and translate business KPIs and OKRs into data models and pipelines.
• Design, build, and maintain scalable data models that support marketplace analytics, including web/app tracking and marketing use cases.
• Write and optimize complex SQL to transform and model data for analytics consumption.
• Build and troubleshoot code-based data pipelines using Python, Spark, and Airflow, jumping in hands-on when needed while guiding the wider engineering team's pipeline work.
• Champion data quality by implementing and maintaining data testing practices across the team's pipelines.
• Evaluate and apply semantic layer concepts to make data more accessible and consistent for business users.
• Explore and adopt AI tooling provided by the company to improve team productivity and data workflows.
• Act as a bridge between the Data Platform Engineering team (who own infrastructure) and the business, ensuring analytics needs are well understood and delivered.
• Deliver on product requirements on time while keeping tech debt and redundancy to a minimum, following best practices and standards.
• Keep yourself and stakeholders aligned with clear, ongoing visibility into project status, surfacing risks early along with a plan and timeline for resolving them.

Requirements:

• Proven experience leading a data engineering team — this role requires genuine people leadership, not just senior-level technical skills.
• Strong ownership mindset, with a track record of delivering reliably on time while minimizing tech debt and redundancy and adhering to best practices and standards.
• 5+ years of hands-on experience in Data Engineering.
• Hands-on experience building data pipelines with Python and Spark — the project's pipelines are code-based (not SQL/dbt-based) — with the ability to jump in and contribute directly when needed, as well as a deep enough understanding to follow and guide what other engineers on the team are building.
• Hands-on experience with Airflow for orchestrating data pipelines.
• Proficiency with Git for version control.
• Strong SQL skills, with the ability to write and optimize complex queries (experience with any SQL dialect is fine — prior exposure to Athena specifically is not required).
• Solid data modeling skills, with experience designing models that serve analytics and business intelligence use cases.
• Excellent communication skills, with the ability to engage business stakeholders and senior analysts to gather requirements and understand KPIs/OKRs.
• Familiarity with data testing practices and tools.
• Familiarity with AI tooling for data engineering workflows.
• English proficiency at B2/C1 level or higher.

Nice to have:

• Experience with marketplace analytics, including web & app tracking and a good understanding of marketing/business metrics.
• Previous experience working with a semantic layer.
• Experience with AWS — the project runs on an AWS data lake, so this is an advantage, though equivalent experience with other cloud providers is also fine given the transferable concepts.

We believe work should have meaning. At Promin, you won't be building "just another app." You'll help shape products that improve people's everyday lives while working with a team that values curiosity, ownership, and thoughtful decision-making.

If you're excited by complex product challenges, experimentation, AI-powered analytics, and having your expertise genuinely influence product direction, we'd love to hear from you.

Promin Apps is a product-first company on a mission to help people feel better, move more, and live healthier lives — physically and emotionally.

At the intersection of AI, data, behavioral science, and personalization, we build thoughtful digital products that support fundamental lifestyle changes — from yoga and fitness to better habits and mental well-being.
Now, we’re looking for a user-centric Product Marketing Manager — someone who will drive real growth by deeply understanding the audience, crafting compelling product narratives, and bridging the gap between user needs and business goals.

— Supportive leadership that values creativity, speed, and initiative;
— Robust infrastructure for rapid experimentation — funnel builder, analytics, and an expanding A/B testing base;

What you will do:

— Design, test, and scale new monetization strategies to outperform market benchmarks and increase ARPU, Conversion, LTV;
— Run A/B tests end-to-end, analyze results, and quickly implement data-driven improvements;
— Research markets, competitors, and user behavior (via interviews, heatmaps, and analytics) to uncover growth opportunities and user pain points;
— Formulate and validate hypotheses across different funnel stages using both quantitative and qualitative data;
— Collaborate cross-functionally with UA, Creative Production, Design, and Analytics to ensure alignment, fast execution, and measurable impact.

What we’re looking for:

— Solid understanding of unit economics, key product and marketing metrics;
— Ability to conduct market and competitor research and analyze user behavior to identify growth opportunities;

About the Project
We are working with a fast-growing, venture-backed US startup building an AI-powered go-to-market automation platform.
The product helps companies find and enrich potential customers, automate outbound communication through email and LinkedIn, generate sales pipelines, and book meetings using AI agents.
The company is growing quickly and is looking to expand its engineering capacity with a strong, product-minded engineer who can work as an embedded member of a small founding team.

The Role
We are looking for a Senior Full-Stack Software Engineer with a strong backend focus.
Approximately 70% of the work will be backend development with Python, Django, and SQL, while around 30% will involve React and product-facing frontend development.
You will work directly with the founders and other engineers, take ownership of product features, communicate with customers, and contribute to technical and product decisions.
This role is best suited to someone who enjoys working in a small, fast-moving startup environment with significant ownership and limited bureaucracy.

Responsibilities
Own product features across the full development lifecycle.
Design, build, test, deploy, and maintain backend and frontend functionality.
Develop backend services using Python, Django, and SQL.
Build and improve user-facing functionality using React and JavaScript.
Architect scalable and maintainable technical solutions.
Work with AI agents, data enrichment processes, and automation workflows.
Use AI coding assistants and agentic development workflows to accelerate delivery.
Debug production issues and improve system performance and reliability.
Work directly with customers to understand problems and translate feedback into product improvements.
Participate in product roadmap, architecture, and technical strategy discussions.
Collaborate closely with the founders and the rest of the engineering team.
Communicate progress, risks, and technical trade-offs clearly.

Required Experience
5+ years of professional software development experience.
Strong commercial experience with Python.
Strong knowledge of SQL and relational databases.
Experience building and deploying software used by real customers.
Full-stack development experience, with a stronger focus on backend engineering.
Experience designing APIs, backend services, and production systems.
Ability to independently take a feature from an initial idea to production.
Experience working with modern AI coding assistants or agentic coding workflows.
Strong debugging and problem-solving skills.
Product-oriented mindset and ability to make practical engineering decisions.
Strong written and spoken English.
Ability to work effectively in a fast-paced and sometimes ambiguous startup environment.
Availability for regular working-hours overlap with a New York-based team.

Preferred Experience
Commercial experience with Django.
Experience with React and JavaScript.
Experience with Pandas and dataframe-based data processing.
Experience with Node.js.
Knowledge of AWS or another major cloud platform.
Experience working with AI-powered products, LLMs, autonomous agents, or workflow automation.
Previous experience in sales technology, marketing technology, data enrichment, or B2B SaaS.
Experience working directly with customers.
Experience leading engineers or owning technical initiatives.
Previous experience in an early-stage startup.

What We Value
Ownership
You can independently understand a problem, propose a solution, and deliver it without constant supervision.
Speed
You know how to move quickly while maintaining an appropriate level of engineering quality.
Product Thinking
You consider customer value and business impact rather than focusing only on technical implementation.
Communication
You communicate openly, raise risks early, and collaborate productively with both technical and non-technical colleagues.
Adaptability
You can prioritize effectively and adjust your approach as product and business requirements evolve.
Humble Confidence
You are comfortable presenting strong technical opinions while remaining open to better ideas.
Team and Communication
You will join a small, highly involved startup team and work directly with the company’s founders and engineers.
