Role Description We are looking for a Staff Backend Engineer in EMEA. This position is remote. As a senior technical leader on the team, you will set the technical direction for major areas of our backend platform, including API integrations with 3rd-party vendors and partners, and the core systems that sit at the intersection of the banking, payroll, and timekeeping domains. This is a rare opportunity to build the foundations of a whole new set of personal financial health products. You will shape the architecture, set the engineering bar, and lead the efforts that help users maintain positive cash availability and take control of their financial lives. Working closely with our international product and engineering teams, you will operate in a fast-paced environment where strong system design judgment and the ability to move quickly without sacrificing reliability are essential. What You’ll Do - Set technical direction and architecture for major areas of the backend platform, translating ambiguous product goals into robust, scalable technical strategy. - Design and implement reliable systems and applications in a fully distributed micro-services architecture, leading by example on engineering quality. - Build and maintain integrations with 3rd-party vendors and partners. - Design and implement highly available RESTful APIs supporting user-facing web and mobile applications. - Establish reusable patterns, frameworks, and libraries that ensure scalability and accelerate future product development. - Enforce observability best practices, leveraging tools like logging, metrics, and alerting systems. - Create and maintain detailed technical documentation (architecture designs, APIs, workflows, and system configurations). - Continuously monitor systems for opportunities to maximize performance and scalability. - Mentor engineers and raise the technical bar across the team. Qualifications - You have at least 8 years of professional experience as an engineer, with a track record of operating at a staff or principal level. - You have extensive experience designing and building novel fintech products, ideally from concept to scale. - You have strong system design skills and thrive in a fast-paced environment, balancing speed with long-term technical health. - You have a strong ability to take ownership of large, ambiguous initiatives, driving them from concept to completion while proactively identifying challenges and solutions. - You have excellent cross-functional collaboration and communication skills, and can influence decisions across teams. - You're deeply familiar with complex large scale distributed systems. Requirements - Proficient in backend languages: Go/Golang, Python. - Strong expertise in designing and developing RESTful APIs. - Expertise in SQL and NoSQL database technologies, including data model design and optimization. - Proven experience building reliable and scalable user-facing applications. - Proficiency in message queuing systems such as Kafka (preferred), RabbitMQ, or Flink. - Familiarity with Cloud technologies: AWS/Azure/GCP, serverless, Docker, Kubernetes, ECS among others. - Effective release management experience for ensuring zero downtime and experience with CI/CD frameworks such as Gitlab CI and Github actions.

Materials Engineer & Python Expert - Freelance AI Trainer
MindriftApply → Pass qualification(s) → Join a project → Complete tasks → Get paid. Project time expectations: Tasks are estimated to require around 10–20 hours per week during active phases, based on project requirements; This is an estimate, not a guaranteed workload, and applies only while the project is active. Note: Rates vary based on expertise, skills assessment, location, project needs, and other factors. Higher rates may be offered to highly specialized experts. Lower rates may apply during onboarding or non-core project phases. Payment details are shared per project.
Role Description Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment. This opportunity involves: - Designing computational material science problems to challenge a frontier AI model. - Ensuring problems have verifiable answers by code and require specialized tools like ObsPy, instaseis, pyrocko, MITgcm, flopy/MODFLOW, or others. - Running each problem inside a sealed Linux container with the tool pre-installed and a programmatic judge that grades the model's answer. As an expert author, you: - Pick an anchor tool and design a problem that hinges on its waveform-processing kernels, geophysical inversion routines, sub-surface flow solvers, or community-validated data pipelines. - Write a Python reference solution, supply input files and model or domain definitions where needed. - Decide the numerical answer and how close the model needs to get — with a domain-appropriate tolerance — to count as right. - Test the problem against the model in batches of parallel attempts, tuning the problem difficulty until the agent only succeeds in a small number of attempts. - Submit the task to a senior reviewer in your subfield for feedback to ensure task quality is high. - Tune the problem against batches of parallel runs of the agent, aiming for a pass rate in the 10–30% band. - Learn how agents cut corners, where a simulation stalls, and how flow or inversion models converge. Qualifications - Degree in Material Science or related field. - 2+ years of research, applied, or teaching experience. - Python proficiency for writing reference solutions. - Fluency with — or strong willingness to independently learn — at least one scriptable package: ObsPy, instaseis, pyrocko, MITgcm, xmitgcm, flopy / MODFLOW, or GeoPandas. - Ability to design problems that genuinely require a specialized solver. - Strong written English (C1+). - No prior experience with the listed tools? You're still welcome to apply — as long as you're ready to get up to speed on your own and hit the ground running. Requirements - This opportunity is a good fit for material scientists & engineers with experience in Python, open to part-time, non-permanent projects. Benefits - Compensation of up to $35 per hour equivalent, depending on level and pace of contribution. - Compensation varies across projects depending on scope, complexity, and required expertise. - Note that other projects on the platform may offer different earning levels based on their requirements. Project Time Expectations - Tasks are estimated to require around 10–20 hours per week during active phases, based on project requirements. - This is an estimate, not a guaranteed workload, and applies only while the project is active.
