Job description

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Senior Software Engineer, Production based in Portugal.

We are seeking a hands-on Senior Software Engineer to help operate and improve production blockchain infrastructure serving institutional customers. As part of a small, specialized Production Unit, you will take ownership of live environments, ensuring reliability, safe deployments, rapid incident recovery, and clear communication with customers. You will work across complex systems, investigating issues in code owned by multiple engineering teams and driving fixes through to completion. A key objective is to reduce reactive operational work by turning recurring incidents, manual procedures, and alerts into lasting engineering improvements. The role combines production ownership, systems‑level software development, and close cross‑team collaboration in a globally distributed, AI‑enabled engineering environment. This is a fully remote opportunity for candidates based in the EU or the United States, with Germany falling within the eligible EU locations.

Accountabilities

• Operate production blockchain environments for institutional customers, participating in the 24/7 First Responder rotation and coordinating incidents through to service restoration.
• Lead incident investigations, communicate updates to customers, and prepare detailed root cause analyses (RCAs) that explain what happened and how recurrence will be prevented.
• Make go/no‑go decisions for production changes, ensuring appropriate verification before deployment and validation afterward.
• Execute sequencer rollouts and oversee the safe release of changes across assigned environments.
• Identify and eliminate recurring operational problems by implementing fixes in the sequencer, provers, and supporting tools.
• Transform alerts, runbooks, and manual operational procedures into more reliable software, automation, and improved monitoring.
• Own service‑level objectives for assigned customers, tracking performance against contractual SLAs and reporting results monthly.
• Investigate issues across codebases owned by different component teams, identify root causes, and drive engineering fixes through to completion.
• Support the evolution of production operations so that additional institutional customers can be onboarded without proportionally increasing operational headcount.
• As the platform develops, help support customers operating their own chains, ensuring solutions can be implemented and maintained in external environments.

Requirements

• Experience being on call for a system you have contributed code to, with ownership of incidents from the initial alert through root cause analysis and implementation of a lasting fix.
• Strong software engineering skills in a systems‑oriented programming language such as Rust, Go, C++, or Java. Rust experience is useful but can be developed on the job.
• Ability to investigate and understand code written by other engineers, identify underlying causes, and deliver effective fixes.
• Experience operating production services used by external customers, including communicating incident updates and writing RCAs for customer engineering teams.
• Sound judgment when managing production changes, including the ability to verify deployments and distinguish reversible changes from those that are difficult or impossible to roll back.
• Proven ability to coordinate across engineering teams and drive issues to resolution through influence and technical ownership.
• Willingness and availability to participate in a shared 24/7 First Responder rotation.
• Nice to have: Experience operating blockchain rollups or nodes, including sequencers, provers, or Layer 1 settlement systems.
• Nice to have: Familiarity with Ethereum execution client internals.
• Nice to have: Experience building internal tools or automation that have been adopted by other engineering teams.
• Candidates who meet most of the requirements are encouraged to apply, as some skills can be developed in the role.
• Location requirement: Candidates must be based in the United States or the European Union due to customer jurisdiction and operational requirements.

Benefits

• Base salary: USD $192,000–$230,000 per year. The same range applies to EU‑based candidates, with the final offer determined by demonstrated experience, scope, and results.
• Additional performance‑based variable compensation.
• Long‑term token incentive.
• Medical, dental, and vision coverage from the first day of employment.
• Global health coverage for team members based outside the United States.
• 401(k) retirement plan with a Safe Harbor employer match of up to 4% for eligible US employees.
• Flexible paid time off, public holidays, and two company‑wide closure weeks annually.
• Six weeks of paid parental bonding leave, plus up to ten weeks of paid birth recovery leave.
• Confidential mental health support.
• USD $2,000 home office stipend.
• Company‑provided laptop, refreshed every three years.
• Coworking allowance of up to USD $400 per month.
• Annual learning and development budget of USD $500.
• Company and team offsites.
• Fully remote working arrangement.
• Full‑time engagement available as either an employee or contractor.
• No questions about current or previous salary at any stage of the recruitment process.
