We work across the full lifecycle-from strategy and governance through architecture, engineering, analytics, AI, visualization, and training-for clients including the SEC, PCAOB, DDOT, and DCAA.\nOur clients describe our support as “absolutely excellent” and our people as “instrumental to organization’s success.” Winner of the United Nations COP27 Datathon, our work has earned all Exceptional CPARS ratings, SEC Chair’s Awards, the SEC Vision Award, and recognition from FDA leadership.\nWe are also built differently. Peregrine is the first and only social enterprise organized as a Benefit Corporation and SBA 8(a) company focused on AI and data for government. We believe business success should create client value, social value, and opportunity for our people.\nAs we enter our next stage of growth, we need dependable, motivated, and skilled people who have a combination of intellectual curiosity and intellectual courage. With new clients, larger programs, and expanding responsibilities, the people joining Peregrine now will have the opportunity to help shape the company we become.\nPeople first. Ownership always.\nWe solve problems through people, process, and technology-in that order. Technology matters, but people make transformation happen. That principle defines our culture. Trust and motivation come before competence. We hire people we can trust, who care deeply about what they do, take ownership, learn quickly, help one another, and refuse to walk past a problem because it belongs to someone else.\nAt Peregrine, you are not joining simply to fill a position. You are joining a team, taking ownership of a mission, and helping build a company. If that excites you, we should talk.\nAt Peregrine Advisors, you will own the design and delivery of cloud-native Python services on Amazon Web Services (AWS), carrying each one from refinement through production. But we hire people, not seats. As the work evolves, you will move to where the hardest problems are.\nThis is a full-time W-2 position with a salary of $150,000 to $170,000 per year. It is a hybrid work arrangement based in the Washington, DC metropolitan area, and the commuting cadence varies by assignment. The initial engagement requires United States citizenship and the ability to obtain a Public Trust determination.\nYour first project\nYour first project will likely have you making the design decisions that connect a solution's components and carrying the result through production. Depending on the assignment, you may:\nDesign the Python services and application components that make up your part of the platform, then deliver them.\nBuild automated workflows on AWS Lambda, Amazon Simple Queue Service (SQS), Amazon Simple Storage Service (S3), and Amazon Relational Database Service (RDS).\nDesign the application programming interfaces (APIs), integrations, and data flows that connect your services to the rest of the platform.\nBuild and improve the continuous integration and continuous delivery (CI/CD) pipelines and automated tests your team ships through, and the way it supports production.\nLead code reviews, settle design tradeoffs, work through hard production issues, and mentor the developers around you.\nUse artificial intelligence (AI)-assisted development tools to move faster on implementation and review, and stay accountable for the code you deliver.\nLead quality development practices, including test-driven development, code reviews, and application security standards.\nDevelop accurate project estimates and support project planning, delivery forecasting, and resource allocation activities.\nYou deliver an integrated solution whose parts work together and hold one quality bar. You automate the validations and workflows that used to live in a spreadsheet, and you build the developers around you through the way you work.\nThis is where you start, not the shape of your career here.\nRequirements\n7+ years of professional hands-on back-end software development experience using Python\n5+ years of hands-on front-end software development experience using React.js\nBachelor's degree\nStrong hands-on experience building cloud-native applications on AWS, including AWS Lambda, Amazon S3, Amazon SQS, and Amazon RDS\nStrong experience with relational databases such as PostgreSQL, SQL Server, or Oracle\nStrong experience with NoSQL databases, for example MongoDB or DynamoDB\nAdvanced knowledge of distributed systems, software architecture, design patterns, object-oriented programming, database design, and data modeling\nStrong troubleshooting, analytical, and problem-solving skills\nExperience leading Agile delivery in Scrum or Kanban, with work tracked in an issue tracker such as Jira\nHands-on use of AI-assisted developer tools such as Amazon Q Developer or GitHub Copilot\nDemonstrated ability to lead a development team and mentor its developers\nExcellent communication skills, including the ability to engage executive leadership, business stakeholders, and technical teams\nProficiency in writing, PowerPoint, and Excel\nPreferred\nAn AWS or Python certification\nExperience in federal information technology\nExperience leading technical delivery teams in a client-facing consulting environment\nExperience implementing DevSecOps best practices and CI/CD pipelines\nWho you are\nYou take personal ownership of what you build, and you spend real time making the developers around you better, through code review, through explaining your reasoning, and through the standard you set. Hard calls come to you because you make them well. When priorities shift, you keep the team steady and productive. You experiment, fail, learn, and repeat quickly. You would rather own an outcome than be handed a task.\nWhat you bring\nDeep command of modern cloud development, with the range to develop something new or improve what already runs.\nStrong delivery habits in version control, automated testing, code review, secure coding, and accessibility, with the standing to set those habits for a team.\nThe judgment to choose among competing solution approaches, resolve design tradeoffs across components, and take responsibility for the technical direction of your assigned area.\nThe ability to explain your work plainly to the people who depend on it and to listen carefully to what they need.\nPrecision in work where accuracy and auditability are not optional.\nYou adapt your development workflow as AI tools evolve, using them to help implement, test, and improve the components you own. You give the tools clear context, review and test their output, and remain accountable for the code you deliver.\nWhen we talk\nBe prepared to discuss a difficult problem you worked through, the decisions you made, what happened, and what you learned.\nBenefits\nMedical, dental, and vision with the employee premium fully paid and half of dependent premiums; employer-paid life, accidental death, and short-term and long-term disability insurance; a 401(k) matched 100% up to 4% of salary, vesting immediately; unlimited paid time off; and sponsored professional certifications and continuing education.\nWhat we offer\nYou will work alongside developers, engineers, data scientists, architects, and strategists, on work ranging from strategy to implementation. We support your development across assignments and clients through extensive onboarding, sponsored professional certifications such as the Data Management Capability Assessment Model (DCAM) and AWS technical certifications, and rotation across functions to expand your skills and perspective. The mission is real, the problems are hard, and you own what you ship.\nWhat we commit to\nAs a Benefit Corporation, our commitment runs three ways: real, measurable value for our clients; government that works better for the public; and a team that makes everyone in it better.\nWe hire people who want to help build the firm, not just work at it. If that is you, apply.\nPeregrine Advisors is an equal opportunity employer.\nPeregrine exclusively works with OPEN Data Jobs to recruit our team. Register with OPEN Data Jobs to be considered for this and future openings.","description_format":"text","description_chars":8249,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Hybrid work"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-26T21:21:12Z"}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":4,"reasons":["conf:0","win:early"],"computed_at":"2026-09-27T02:04:13Z"},"pay":{"stated_usd_annual":170000,"is_top_pay":false},"html_url":"https://alion.io/job/open-data-jobs-full-stack-senior-developer-python-react-js","json_url":"https://alion.io/job/open-data-jobs-full-stack-senior-developer-python-react-js.json","meta":{"generated_at":"2026-09-27T02:04:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":1825,"day_limit":5000,"remaining_today":3175,"minute_limit":60,"resets_at":"2026-09-28T00:00:00Z"}}}
