Résumé du poste

Lever, Inc. is seeking a Staff Engineer – Pricing to own the Pricing API and related backend systems in a remote-first setup. You will drive architecture, ensure accuracy and performance of energy pricing quotes, and lead cross-team decoupling initiatives for a scalable pricing platform.

The role emphasizes Python backend engineering, FastAPI, and data-intensive systems, with exposure to AI-assisted development and multi-agent workflows. External API readiness is a plus.

Qualifications

• Deep production experience with Python backend engineering and APIs at scale.
• Proven ownership of production systems and escalation handling.
• Led decoupling or architectural transformations of live systems.
• Strong proficiency with FastAPI and SQL in data-intensive environments.
• Experience designing systems where data accuracy, performance, reliability, and explainability matter.
• Ability to set technical direction across organizational boundaries.

Responsabilités

• Build, evolve, and operate the Pricing API for fast, reliable, and explainable pricing.
• Lead extraction of pricing logic into a dedicated service.
• Manage architectural migrations while protecting functionality.
• Own pricing reliability with monitoring and alerting.
• Explain pricing failures and improve diagnostics.
• Improve pricing performance and reduce latency.

Description du poste

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Staff Engineer – Pricing based in France.

This is a high-impact staff-level engineering role focused on building the pricing infrastructure behind a modern energy transaction platform. You’ll own the backend and data-heavy systems responsible for pricing real energy contracts, where correctness directly affects financial outcomes and performance builds customer trust. You’ll shape a new Pricing API from initial architecture through production readiness and eventual third-party access. The role combines backend engineering, numerical systems, data, reliability, and product thinking in a highly consequential domain. You’ll also lead significant architectural decoupling, establish engineering standards, and influence technical direction across teams without relying on formal management authority. The environment is remote-first, collaborative, and focused on using modern AI-assisted engineering workflows to increase team productivity.

Accountabilities:

• Build, evolve, and operate the Pricing API, ensuring it is fast, reliable, accurate, explainable, and ready for third-party consumption.
• Lead the extraction of pricing logic from surrounding systems into a dedicated service, establishing clear and maintainable boundaries with neighboring teams.
• Manage significant architectural migrations and decoupling initiatives while protecting existing functionality and minimizing disruption to dependent systems.
• Own pricing reliability by designing detection, monitoring, and alerting systems that identify incorrect or slow prices before they reach customers.
• Ensure every pricing failure can be understood and explained, creating robust mechanisms for diagnosing why a quote cannot be produced.
• Improve pricing performance and reduce quote latency across the customer experience through architectural and technical optimization.
• Act as a senior technical authority within the pricing domain, contributing to architecture decisions, design reviews, engineering standards, and development practices.
• Raise the effectiveness of the wider engineering team through pairing, knowledge sharing, technical guidance, and AI- and multi-agent-assisted development workflows.
• Serve as a key escalation point for live pricing incidents and convert operational learnings into durable architectural and product improvements.
• Balance speed, numerical correctness, reliability, cost, and explainability when making technical and product engineering decisions.
• Influence technical direction across teams, negotiating service boundaries and aligning stakeholders without direct management responsibility.

Requirements:

• Deep production experience with Python backend engineering, including designing, building, and owning APIs at scale.
• Demonstrated experience taking technical ownership of production systems and acting as a senior escalation point when complex backend issues arise.
• Proven experience leading a significant decoupling, migration, or architectural transformation of a live system without disrupting critical dependencies.
• Strong proficiency with FastAPI and SQL, ideally within data-intensive or analytics-heavy systems where numerical correctness has direct financial consequences.
• Experience designing systems where data accuracy, performance, reliability, and explainability are critical requirements.
• Ability to establish technical direction across organizational boundaries and negotiate effective service contracts and ownership models with neighboring teams.
• Strong product engineering judgment, with the ability to understand how pricing information is consumed and deliberately balance speed, accuracy, and explainability.
• Experience using AI coding tools such as Claude or similar technologies as part of everyday engineering workflows.
• Ability to design and implement multi-agent engineering workflows that improve development throughput across a team, rather than simply using AI tools individually.
• Strong communication and leadership skills, with the ability to influence senior engineers and stakeholders without relying on formal authority.
• Experience with energy pricing, fintech, financial systems, or modern utility platforms is desirable.
• Experience building APIs intended for consumption by external third parties is a plus.
• Familiarity with AWS and serverless architectures, including Lambda, event-driven services, and PostgreSQL on RDS, is beneficial.
• Experience with Polars or a demonstrated track record of optimizing numerical and data-processing code is an advantage.

Benefits:

• Competitive salary: Compensation is positioned at a competitive level for a Staff Engineer role, with the exact local equivalent determined by location and experience.
• Stock options: Receive equity so employees can share in the long-term value created by the business.
• Generous time off: 25 days of annual leave plus public holidays, with the flexibility to swap public holidays for days that are more meaningful to you.
• Birthday leave: Enjoy your birthday as an additional day off.
• Remote-first working: Work remotely with flexible arrangements and clearly defined core hours.
• Meeting-free Friday afternoons: Dedicated time for focused work, learning, and personal priorities.
• Remote-work allowance: Up to £1,200 or €1,400 per year toward your home-office and remote-working setup.
• Wellbeing allowance: Up to £150 or €170 per month to support your health and wellbeing.
• Inclusive environment: Applications are welcomed from people of all backgrounds, experiences, and identities, including those traditionally underrepresented in technology and energy.
• High-impact technical ownership: Work on infrastructure where engineering decisions directly influence financial accuracy, customer trust, and the modernization of a major global industry.
• Modern engineering culture: Contribute to an environment that embraces AI-assisted and multi-agent engineering workflows and encourages continuous improvement.
