• Oversee the creation, refinement, and adjustment of Civil and Electrical engineering drawing sets, managing the workflow from Initial Layouts -> Permit Sets  -> Construction Release.
• Manage and coordinate cross-functional design teams (civil, electrical, structural, architectural) to produce complete, compliant drawing sets.
• Standardize design processes, templates, and specifications to improve scalability and consistency across sites.
• Drive "design for deployability" by providing feedback loops to hardware engineering teams based on field insights and jurisdictional constraints.
• Permitting and Regulatory Tracking
• Oversee permitting submissions across multiple sites, metros, and jurisdictions, , including coordination with Authorities Having Jurisdiction (AHJs) and utility providers as needed. 
• Act as the primary internal manager of the submission process, incorporating city comments, and securing approvals to fast-track permit release.
• Cross-Functional Collaboration and Handoff
• Act as the primary point of contact across internal stakeholders, external consultants, and third-party partners.
• Partner with Real Estate, Civil/Electrical Engineers, and Construction Managers to ensure site designs are both compliant and "buildable".
• Support contractor bidding and preconstruction activities by ensuring the completeness and clarity of construction documents.
• Coordinate the handoff to construction teams, ensuring alignment on scope, design intent, and execution requirements.

What You’ll Bring

• Foundational Experience and Education
• Possess a Bachelor’s degree in Architecture, Engineering, Construction Management, or a related technical field (or equivalent practical experience).
• Have 6-10+ years of experience in Design Management, Civil Engineering, Architecture, Infrastructure Delivery, site development, infrastructure projects, or light commercial construction.
• Prior experience as an Engineer of Record (EOR) or Architect of Record is a plus.
• Experience in industries such as EV charging infrastructure, solar, telecom, or commercial site development is preferred but not required.
• Technical Fluency and Design Knowledge
• Deep understanding of construction drawings and specifications across multiple trades and disciplines.
• Basic knowledge of civil engineering design, including grading, drainage, and utilities, and basic knowledge of electrical site design fundamentals, including distribution and NEC codes.
• Ability to read, interpret, and review technical drawings and specifications across multiple disciplines.
• Project Management and Execution
• Demonstrated experience managing multiple concurrent, high-priority, and "0 to 1" projects through design, permitting, and construction documentation phases without losing critical details.
• Proven ability to manage schedules, budgets, and cross-functional dependencies in complex projects.
• Familiarity with project management tools like Procore or Bluebeam is a plus.
• Experience managing external consultants (engineering firms, architects) and driving deliverable accountability.
• Regulatory and Permitting Expertise
• Familiarity with permitting processes, zoning requirements, and coordination with local jurisdictions and utilities.
• Communication and Adaptability
• Strong communication and stakeholder management skills, including the ability to interface with technical and non-technical teams.
• Ability to translate complex technical decisions into clear business value for customers and simple "actionable tasks" for contractors.
• Experience working in fast-paced, evolving environments where progress must be driven with imperfect or ambiguous information (Resilience and Grit).

• CAD Experience: Familiarity with CAD software (e.g., Autodesk products) or a demonstrated willingness to learn independently

Zipline's "Great" Candidate Criteria

• Good candidates manage the checklist; Great candidates challenge requirements to ensure the best outcome for the company’s scalability.
• Great candidates don't just solve problems; they implement systemic changes to prevent the problem from occurring in the next 100 sites.
• Great candidates treat permits not as a bureaucratic hurdle, but as a strategic milestone to be proactively shaped and accelerated.

Navan is seeking a Senior Applied Economist to join the Data Science & Machine Learning team. This is a foundational, "first-of-its-kind" role at Navan, designed for a technical leader who can bridge the gaps between hands-on machine learning, rigorous economic theory, and driving business outcomes.

In this role, you will be the primary architect of our internal economic "brain." You will move beyond point-estimate forecasting to build sophisticated models that account for market nuances, uncertainty, and causal drivers. You will partner closely with Finance, Treasury, and FP&A to steer the company’s financial trajectory, while providing the strategic frameworks that Sales and Pricing teams use to maximize customer adoption and revenue.

What You’ll Do:

• Next-Generation Forecasting: Uplevel our existing forecasting pipelines (currently built on Prophet). You will integrate econometric rigor to improve accuracy and, crucially, provide a range of likely outcomes (probabilistic forecasting) that Finance and Treasury can rely on for risk management.
• Causal Inference & Strategy: Design and execute experimental and quasi-experimental frameworks to identify the "levers" of the business. You will answer critical questions regarding price elasticity, product feature attribution, and the ROI of sales incentives.
• Strategic Blueprinting: Partner with Sales and Account Management to create data-driven frameworks for pricing and customer retention. You will translate complex causal models into actionable blueprints for go-to-market teams.
• Production-Level Data Science: Work hands-on within our ML infrastructure. You will write production-quality Python code to deploy models into our AWS and Snowflake-based ecosystem, ensuring your insights are automated and scalable.
• Internal Advisory: Act as the subject matter expert on economic literature and methodology, translating technical findings into strategic recommendations for executive leadership.

What We’re Looking For:

• Education: An advanced degree (PhD preferred, Masters required) in Economics, Statistics, or a related quantitative field with a heavy emphasis on econometrics or causal inference.
• Experience: 4+ years of post-academic experience in an applied research, finance, or data science role, ideally within a high-growth tech environment or fintech.
  • Technical Proficiency:
    • Deep expertise in Python and its data science ecosystem (pandas, statsmodels, scikit-learn, etc.).
    • Advanced SQL skills, with experience querying large-scale data warehouses like Snowflake.
    • Experience working in production environments and a strong understanding of the ML lifecycle is nice to have.
• Econometric Mastery: Proven ability to apply advanced methods (e.g., Synthetic Control, IV, Diff-in-Diff, Structural Modeling) to messy, real-world datasets.
• Self-Starter Mentality: Experience functioning in "underdefined" spaces. As our first economist, you must be comfortable setting the roadmap.
• Communication: The ability to explain not just the "what," but the "why" and the "what if." You can communicate uncertainty and risk to a CFO just as clearly as you can discuss model architecture with an ML Engineer.
• Preferred Qualifications:
  • Prior experience in Fintech, Payments, or Travel industries.
  • Experience building and scaling "first-of-their-kind" functions within a data organization.

About Us:

Samara Aerospace is revolutionizing satellite design by addressing the challenges of deploying and managing large satellite constellations. Our innovative Hummingbird spacecraft bus offers a modular and scalable platform that streamlines satellite production and deployment, significantly reducing launch costs. Hummingbird's compact architecture maximizes launch capacity, making it the most efficient and agile spacecraft in the industry. At the core of our technology is the patented Multifunctional Structures for Attitude Control (MSAC) system. Unlike traditional wheel-based pointing control systems, MSAC utilizes actuators embedded in the hinges of deployable solar panels to provide 3-axis attitude control and active jitter cancellation. This design eliminates the need for spinning wheels, reducing mass and potential points of failure, while enhancing pointing precision.
